1. Scope and Applicability

This PCR covers accepted blast-furnace metallurgical coke made from coking-coal blends in conventional indirectly heated by-product slot ovens, followed by wet quenching, draining, sizing and bulk dispatch. The foreground includes actual coal handling/preparation, battery operation and fuel firing, wet-quench water recovery, gas cooling/tar separation, ammonia capture as ammonium sulphate, wash-oil absorption/stripping of crude benzol, actually installed gas desulphurisation, utilities, abatement, storage and wastewater handling. EPA Section 12.2.1 and JRC BREF Chapter 5 provide manufacturing evidence; neither establishes a universal configuration or current site performance. [epa-coke-production-2008; jrc-iron-steel-coking-2013]

Exclude petroleum-coke refinery coking, peat or lignite coke, semi-coke, retort carbon, foundry-grade coke, dry quenching and non-recovery/heat-recovery ovens. Exclude downstream tar distillation, BTX refining, gas-to-methanol/hydrogen and coke use in ironmaking. A plant using another ammonia-recovery route, wet-oxidation desulphurisation chemistry, oil-addition coal recipe or dry quenching needs a separately evidenced extension before using this method. Do not splice those operations into the present route.

Actual gas desulphurisation within this subset is either absent or an evidenced absorption/stripping unit with elemental-sulphur recovery. Acid-producing and wet-oxidation desulphurisation routes require a separately reviewed extension; their genuine products must then be inventoried, rather than omitted. [jrc-iron-steel-coking-2013]

Required qualifiers	coal grade/blend and origin; conventional by-product oven and charging method; wet quenching; gas-cleaning process diagram; coke lot/grade/size; received and dry mass/moisture definitions; coal/coke/tar carbon and sulphur bases; NCV/GCV sampling bases; gas wet/dry composition/T/absolute P/Z; internal/exported gas and fuel boundaries; supplier steam state and condensate; campaign/site; stock correction; coproduct receivers; allocation method and unallocated amounts

Declare all required qualifiers in the dataset metadata, reference comment or equivalent package fields. Missing qualifiers make the reference definition incomplete. The selected coke product is at the coking-plant gate, with coking route and primary Mass/kg reference. Its complete native record explicitly identifies the named secondary 28.2 MJ/kg NCV as an IPCC default and states that no plant-specific coke grade is specified. That documented secondary descriptor does not impose a site calorific grade: this method uses the primary mass reference and does not apply the default energy conversion. Product identity is positively established by the coke name, carbonized-coal/blast-furnace-fuel synonyms, coking route, plant gate and the cited coal-coke definition; it is not inferred from a classification code alone. Only the actually accepted wet-quenched, drained and screened blast-furnace coal-coke subset belongs to this reference. Collect actual lot moisture, NCV/GCV/test bases and supplier quantity/route compatibility before concrete dataset binding; neither a site calorific value nor its dry/as-received test basis is inferred from the secondary property. [ipcc-energy-fuel-definitions-2006; jrc-iron-steel-coking-2013; epa-coke-production-2008]

The reference, inventory denominator and collection/calculation basis are one measured net 1 kg dispatch product mass, independent of any database secondary heating factor. Conditional input/waste identity suggestions with unclarified named grades and NOx aggregate conventions remain unavailable for concrete binding until clarified; they do not replace measured physical exchanges or invalidate the declared mass method. Add compatible identities for actually applicable materials while preserving every physical stream and its measured basis. Scientific methodology acceptance and acceptance of any classification mapping are separate decisions; field-data collection and supplier binding are not claimed complete.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	coke_dispatch	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Use 1 kg net accepted coke on the declared as-received dispatch basis; weigh with cp_coke and exclude packaging and breeze. Measure moisture on representative dispatch samples and retain the independently derived dry equivalent. All inventory rows and collection aggregation use this same coke denominator.
material_bases	coal_charge; coke_dispatch; crude_tar_dispatch; crude_benzol_dispatch; ammonium_sulphate_dispatch	Mass	kg	For each material record as-received mass and water fraction independently; dry mass = wet mass × (1 − wet-basis water fraction). Dry ash-free, dry and received carbon/sulphur/heat bases are distinct; convert using that material’s analysed water/ash, never another material’s moisture. cp_material/cp_products/cp_coke retain samples and methods.
gas_bases	cog_export; natural_gas_import; nitrogen_makeup	Mass or Volume, according to verified reference property	kg; m3	Store measured gas volume with T, absolute P, water fraction, composition and Z. Conversion to a specified dry reference volume follows the documented equation-of-state protocol; conversion to mass uses the same measured composition and state. Do not assume Nm3 temperature or pressure, density or NCV. Self-produced gas gross and internal links remain equal on both ends.
packaging_count	sulphate_bags	Number of items `01846770-4cfe-4a25-8ad9-919d8d378345`	Item(s)	Collect the count of the same declared complete empty-bag specification using cp_packaging; if only packaging mass is recorded, derive count using the measured net empty bag mass from actual representative samples, never a database default bag weight. Keep packaging separate from net ammonium sulphate mass.
energy_bases	electricity_import; steam_import; natural_gas_import	verified energy property plus independent carrier quantity	MJ; kg; m3	Keep electricity, fuel chemical energy and net supplied steam enthalpy in separate ledgers. For electricity preserve the actual direct-read property and use 1 kWh = 3.6 MJ. For coal/coke/gas keep NCV and GCV and sampling water basis separate. Steam net heat requires mass × (supply enthalpy − return enthalpy) on the provider boundary including dryness/pressure; unknown basis prevents the background link.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	delivered coking coal and separately metered supplies at the coal-handling inlet; coal washing upstream unless actually included
starting_condition_role	foreground_entry
product_classification_scope	narrower portion of CPC 3.0 33110; physical coal-coke identity governs
recursive_input_rule	purchased same-category coke is a separately weighed external input with its own upstream dataset; internally recycled breeze/dust is an equal physical link, never new production
upstream_dataset_requirement	required for delivered coal, each supply and external waste treatment; verify route, property, water/heat/gas and delivery boundary compatibility
disclosure	site; campaign; charging; coal preprocessing; wet quench; gas-cleaning diagram; utilities; treatment gates; raw and allocated ledgers; missing identities; capital/transport and cut-offs

rule_id	applies_to	Rule	source_ids
boundary_route	coking_plant	Confirm the actual site route against the cited manufacturing descriptions and a site diagram. Wet quench excludes a dry-quench gas loop and dry-quench recovered steam/electricity credit. Coal pretreatment includes actual crushing/blending/handling; purchased coal washing is upstream unless physically included and separately collected.	jrc-iron-steel-coking-2013; epa-coke-production-2008
boundary_gas	coking_plant	Include actual gas primary cooling, tar separation, ammonia-sulphate recovery, final cooling, selected wash-oil light-oil recovery and installed absorption/stripping desulphurisation. Keep their measured configuration; BREF alternatives do not license mixing unrelated scrubbers/catalysts. Exclude downstream chemical refining at the outgoing gate.	jrc-iron-steel-coking-2013; epa-coke-production-2008
boundary_interfaces	coking_plant	The aggregate foreground retains stage measurements and equal internal links for hot coke, raw/clean gas, condensate, flushing/quench liquor, tar residue and lean/rich wash oil. Internal transfers cancel only in the aggregate external-exchange table; do not erase them from the physical process graph or charge a second upstream dataset. Imported versus internally generated heat/gas and flare feed are separately reconciled.	jrc-iron-steel-coking-2013
boundary_water_emissions	coking_plant	Collect quench/cooling net make-up, recycle, evaporation, coke water, bleed and recipient returns independently. Include actual abatement and on-site effluent treatment. Treat externally transferred wastewater as a waste exchange; only actual environmental discharge after the selected treatment endpoint is an elementary emission. Document cooling configuration and abnormal bypasses.	jrc-iron-steel-coking-2013
boundary_upstream	coking_plant	Link each external input to an applicable upstream dataset with independently verified quantity/supply basis. Include actual start-up, shutdown, flaring, off-spec handling and maintenance in the campaign. Disclose initial capital construction and any separately reported transport; no unsupported infrastructure lifetime or exclusions hidden in a yield factor.	jrc-iron-steel-coking-2013

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
coking_plant	Coal preparation, battery, wet quench/sizing and by-product recovery with actual utilities/treatment	required	documented included route	foreground	coke_dispatch

The foreground is one aggregate unit to retain a single final coke reference. Independently meter the physical stages below; intermediate hot coke is the same product in transit and is not a second final reference output. All cards describe external exchanges; none is a default positive amount.

Stage	Physical inlet/outlet and retained measurements
coal	delivered grades → actual crushing/blending/charge; weighing, stock, moisture and recycled tar/sludge
battery	charge and indirect firing → hot coke + raw gas; charge/push schedule, fuel, stack and door/lid/offtake release
wet_quench	same hot coke → wet cooled coke → drained/sized dispatch and breeze; make-up/recycle/evaporation, dust and product water
gas_recovery	raw gas → tar/water separation → sulphate/light-oil recovery → installed desulphurisation; clean gas split to battery/export/flare; lean/rich oil and liquor loops
treatment_utilities	actual gas/water control units and supplies → source-resolved outdoor releases, treated return or external waste transfer; sludge fate

The physical ledger includes total wet combustion/infiltration air (dry O2/N2 and actual humidity), complete wet flue gas and gas losses, all material-bound water, rain/runoff, reaction water, quench slurry/settling-basin stock and sludge removal, condensate and every actual residual. Measure or explicitly model air/exhaust quantities with source-bound composition and uncertainty; dry N2/O2 carrier exhaust is retained in the physical balance even where an LCIA inventory does not characterize it. Never treat an unmeasured balancing flow as zero. Keep species loads as analytical partitions of whole materials, not extra kilograms added to their carrier water/waste or mixtures. [jrc-iron-steel-coking-2013; epa-coke-production-2008]

Maintain a separate physical ledger for every actual supplier container/liner/closure and transport packing, delivery and return, reused stock, maintenance replacement and removed part. Add one atomic row for each actual complete specification or separately handled component; this method does not assume a drum, bag liner or pallet exists. Bundled supplier packing, cleaning, return transport and lifecycle service burdens are counted once at documented provider boundaries; returnable assets are not fabricated net material consumption. Maintenance and capital/service burdens use an evidenced campaign attribution, never an invented furnace count, lifetime or replacement recipe.

Inputs

Product flows

hard coal, coking coal (`coal_charge`)

Use this UUID only for washed/processed main coking coal at the declared coal-washing-plant supply gate, with the named 26.377 MJ/kg NCV grade and its source-authorized water/test basis verified. It is not an unrestricted blend identity. Unclarified named-grade basis prevents binding; separately collect all other real blend components and their upstream delivery/transport gates.

Record each delivered coal grade separately, including purchased blend composition, wet mass, moisture, ash, carbon, sulphur and NCV/GCV bases. This identity covers coking coal, not every other blend component; add individually verified component rows when required. No coal recipe is prescribed.

Alternating current (`electricity_import`)

Use this identity only for CN grid-average consumption mix supplied to the user at measured 1–35 kV; other voltage or supply boundaries need their own verified identity. Separate stage meters and grid losses from the supplier boundary; do not use Korean electricity or a grid-service flow as generic electricity.

natural gas in the gaseous state (`natural_gas_import`)

The native route is compressed processing and pipeline delivery to consumption in compliance with the applicable national gas standard. Confirm that actual route, receiving gate and applicable quality specification. The listed methane CAS does not make this natural-gas mixture pure methane; use actual component fractions, including CO2/N2/H2O, for mass and elemental balances. If the supplier cannot define the reference m3 state, the quantity link is blocked.

Only actual supplementary firing/start-up gas. Meter temperature, absolute pressure, water fraction, composition and compressibility; reconcile supplier reference m3. The secondary mass factor is not a density. Self-produced coke oven gas is an internal link, not this input.

supplied steam for coke-oven aspiration and by-product stripping (`steam_import`)

Separate imported steam, self-generated steam, condensate return and vented/retained water. Physical steam mass is collected even where usable enthalpy or an upstream provider is unresolved; no supplier heat is multiplied twice into the same steam mass and thermal service.

Record actual delivered steam pressure, temperature, dryness or superheat, mass and condensate return. No 11.0 or 0.45 MPaG identity is selected without pressure agreement. Use independently measured net delivered enthalpy for a heat background; MJ alone does not prove its basis.

This card represents one external supply header; independently supplied pressure/temperature/dryness states require separate atomic rows and cannot be merged merely because both are steam. No paper-line or deodorisation-specific supply identity is adopted for coke manufacture.

Only actual supplied treated tap water; net external make-up for coal wetting, wet quench, cooling and washing is stage-resolved. Meter volume is converted using measured density; database secondary conversion is not a site measurement.

Wash oil (`coal_tar_wash_oil`)

The name and full comment both specify 33.453 MJ/kg NCV. This grade and its authoritative water/test basis must match the actual coal-tar-distillation oil before binding; the secondary factor is not a default recipe, density or measured loss.

Coal-tar-distillation-derived wash oil make-up only. Record grade, composition, origin, wet mass and regenerative cycle loss. The petroleum classification conflicts with the name/comment/route; supplier clarification is required. Recirculation is not new input.

Sulfuric acid (`sulfuric_acid_input`)

Fresh acid supplied for ammonium sulphate recovery only when its measured supplied mass fraction is 93–98%, as limited by this record. Keep supplied acid solution, pure H2SO4 equivalent and diluted saturator liquor separate; another concentration needs another identity.

Sodium hydroxide (`sodium_hydroxide`)

This source explicitly specifies industrial-grade white crystalline solid of 95–98% purity, associated with chlorine production. Require actual purchased solid purity and producer route agreement. Separately record dissolution water and resulting dosing liquor; a purchased dilute caustic solution requires a different verified identity.

Only actual alkaline dosing in the ammonia still or wastewater treatment. Declare supplied form and concentration and verify that the background quantity represents that form, rather than silently treating a solution as pure NaOH.

Potassium carbonate (`potassium_carbonate`)

The native identity is synthesized K2CO3 powder/crystals, molar mass 138.205 g/mol; it does not represent the complete regenerated scrubber solution. Independently assay purchased salt, water and other actual additives, and retain lean/rich solution inventories.

Only an actually installed carbonate absorption/stripping desulphurisation circuit. Verify site flow diagram, concentration, regeneration and downstream sulphur recovery; do not add wet-oxidation catalysts or their wastewaters to this circuit.

Woven polypropylene bag (`sulphate_bags`)

Only actual ammonium-sulphate packaging, recorded separately from net sulphate mass. Verify whether the supplied bag includes liners; additional liner material is a separate atomic row. Bulk coke is unpackaged within this route.

Count actual complete bags of one declared specification in items; measure empty-bag mass and record actual capacity, weave, coating, liner, closures and supplier gate.

Outputs

Product flows

metallurgical coke (`coke_dispatch`)

Use the coke product on the Mass/kg basis defined in Section 3, confined to the accepted high-temperature coal-coking, wet-quenched final product at dispatch. The explicitly documented secondary IPCC default does not supply a site heat value, calorific grade, energy conversion or coke yield. Record actual acceptance strength/reactivity tests and methods without inventing CSR/CRI limits.

Accepted blast-furnace-grade wet-quenched coke after draining, sizing and stock reconciliation, as received at the dispatch gate. Exclude coke breeze and packaging; retain dry equivalent and product water separately.

Coke Breeze (`coke_breeze_dispatch`)

This broad manufactured finished-product record expressly includes coke breeze. Use only the actual screened coal-coke fines subset; it does not admit lignite, semi-coke or retort carbon to this PCR. Measure the actual NCV/water basis; no conflicted named calorific grade or secondary energy factor is adopted.

Actual separately recovered/accepted screened coke breeze leaving for another use. Record sieve class, water and receiving process; captured particulate returned internally is not a second sale.

coke oven gas (`cog_export`)

The native composition percentages are approximate descriptive context, not a fixed recipe or a complete composition. Measure all actual fractions and water, and reconcile moles/mass, C/H/O/N/S and NCV/GCV without renormalizing away unmeasured components. The verified reference is Mass/kg; site volume and any receiving Volume/m3 basis need independently declared P/T/Z and wet/dry definitions.

Only net cleaned coke oven gas crossing the coking-plant boundary. Keep gross production, battery firing, other internal uses, flare feed, leaks and storage changes in the gas ledger; do not normalize volume by an assumed density or heating value.

Coal tar (`crude_tar_dispatch`)

The selected name fixes 33.453 MJ/kg NCV and coal carbonisation at the plant gate. Verify the authoritative water/test basis and actual tar grade before binding; neither the source comment nor its secondary value supplies a default assay.

Actual recovered crude coal-carbonisation tar after the declared water separation only. Retain residual water, solids, carbon and sulphur; exclude coal-tar distillation, pitch and downstream creosote. Coordinate the outgoing gate with a receiving tar PCR.

Polypropylene bags delivered with ammonium sulphate (`sulphate_packaging_dispatch`)

Record the actual count of the same declared-specification bags leaving with net ammonium sulphate; preserve empty-bag net mass and loaded gross mass independently in the physical balance. The bag is an attached packaging component, not a second bag production or separately revenue-earning co-product; assign no independent allocation share. Reconcile issued, delivered, discarded and stock counts through cp_packaging; any actual discarded packaging requires its own waste row.

recovered elemental sulphur from coke-oven-gas desulphurisation (`recovered_sulphur_dispatch`)

Only actual elemental sulphur at a documented absorption/stripping and sulphur-recovery outlet; purity, water and destination are required. Rubber-curative records are not adopted as a recovered sulphur specification. No default sulphur yield or simultaneous acid co-product.

Require a verified recovered-elemental-sulphur identity for the actual coke-gas outlet and purity. A native vulcanization-agent route does not establish the recovered product, and a refinery by-product route does not establish coke-gas origin. Keep the physical sulphur output, assay and receiving gate even when its identity is unresolved.

liquid steam condensate returned to the supplying utility (`steam_condensate_return`)

Only actual external condensate return on the same supply/return utility boundary. Measure liquid mass, temperature/pressure, contamination and recipient, retaining heat and water ledgers. An internal condensate loop is an equal internal pipe, not this exchange; no separate sale or allocation share is assumed.

Waste flows

Coal tar, residue (`tar_residue_external`)

The named 31.4 MJ/kg NCV and tar-production origin are binding restrictions, not a generic residue heat value. Clarify water/test basis and actual residue grade before linking; do not infer energy from this secondary factor.

Only residue physically exported from tar separation/storage; quantify wet mass, water, PAH, carbon/sulphur and receiving treatment. Same-period residue returned to coal feed remains in the internal balance, not this exported waste.

spent wash oil from coke-oven light-oil absorption (`spent_wash_oil_external`)

Only a real purge sent to treatment; identify coal-tar/petroleum origin, entrained benzol, water, regeneration history and receiver. Lean oil circulating back to absorption is an internal link.

The generic waste-oil identity has no machining, lubricating or refining origin restriction. Limit it to this actual spent absorber oil with source, water/benzol contamination, hazard state and receiver documented; the broad identity does not establish a treatment dataset.

dewatered biological sludge from coking wastewater treatment (`biosludge_external`)

Only actual external removal; keep dry solids, water, contaminant analyses and receiver. Municipal or paper-mill sludge identities do not establish this origin; sludge recycled to ovens is internally reconciled.

Require a verified generated biological-sludge identity; an ambiguous water-treatment-chemical route cannot be waived by a broad general comment. Measure water/dry solids/PAH and C/H/O/N/S, actual biological origin and recipient acceptance. Do not substitute dry sludge, municipal sludge, return activated sludge or wet-quench sediment.

coking wastewater transferred to external treatment (`coking_wastewater_external`)

Only liquid actually crossing to an external treatment process. Electrolytic-manganese-residue washing wastewater is incompatible. Do not also report its contents as direct freshwater emissions before treatment.

This broad industrial-wastewater waste flow is linked only when the actual receiving boundary is secondary/tertiary treatment and the measured coke-effluent load/pretreatment is acceptable. Its primary Mass/kg reference does not prescribe pollutant concentrations; convert paired actual volume to mass with measured density and never use it as a direct freshwater emission.

Only actual external removal of the complete wet settled coal/coke slurry. Independently measure wet mass, water, dry solids, ash and C/H/O/N/S/PAH, settling origin and receiver. Keep wet-quench sediment separate from dry captured dust, saleable breeze, tar residue and biological sludge. Returned solids/liquor remain paired internal links; unmeasured removal is not zero.

Nitrogen oxides (`nox_air`)

Explicitly declare whether the amount is sum of NO and NO2 species masses or NO2-equivalent mass, and verify the receiving inventory/LCIA definition; the native record does not resolve this. Preserve constituent observations in the auxiliary balance ledger. Never emit the aggregate and its same NO/NO2 constituents as duplicate exchanges; N2O remains separate. Unmatched aggregate basis blocks use.

NO+NO2 aggregate only, excluding N2O. Declare whether laboratory mass is species mass or NO2-equivalent and verify agreement with the receiving LCI/LCIA flow; identity Mass/kg alone does not resolve that definition. Do not additionally count NO/NO2. Outdoor air, unspecified subcompartment; preserve stack height/source context and refine the identity for site-specific compartment evidence.

Stock reconciliation retains both quantity and embodied burden. Track opening/closing coal, coke, each coproduct, oil/chemical, packing and waste by lot and stage. Opening stock plus receipts/production equals actual dispatch/use/returns/removal plus closing stock, with separate measured or justified loss and uncertainty. Match the dispatch cohort to its production records; preserve opening embodied burden and burdens carried into closing stocks, off-spec material and actual returns before attributing the delivered cohort. Do not divide an unmatched manufacturing period by sold coke or apply a revenue share to erase physical stock changes. Record prices as net gate product prices on one declared mass/energy basis, currency, date and taxes/transport/packing convention; reconcile measured quantities times prices to actual revenue rather than using invoice gross mass.

7. Allocation and Co-product Handling

rule_id	applies_to	Rule	source_ids
allocation_physical	coking_plant	Keep the unallocated physical graph and mass/C/H/O/N/S/water/energy ledgers separately from burden allocation. Never multiply the real coke, breeze, gas, tar, benzol, sulphate or recovered sulphur quantities by allocation shares. Internal gas, recycle liquor and residue returns are not saleable co-products at this boundary. Packaging dispatched with a chemical product is an attached physical component with no separate co-product revenue/share; retain its real count/mass and attribute its manufacturing burden only once to that packaged product.	jrc-iron-steel-coking-2013
allocation_direct	coking_plant	Under this authored attributional protocol, first assign independently measured separable processing burdens to their actual products. Document any remaining demonstrable physical causal relationship; mass or calorific allocation is not automatically causal for gas/liquid/solid chemical recovery. Record decisions and evidence through cp_allocation.
allocation_shared	coking_plant	If separability and physical causality cannot be established, use documented actual campaign net gate revenues for remaining shared burdens, with cp_allocation: share_j = revenue_j / sum revenues of all genuine exported co-products; assigned burden_j = directly attributable burden_j + share_j × residual shared burden. Retain every qualifying product, common pricing units/currency/period and sensitivity to another justified basis. Do not assign a share to an internal gas loop or waste sent for paid treatment. Zero/negative or missing revenues require reviewed resolution, not an invented fraction.
allocation_export	coking_plant	Exported clean gas, crude tar and crude benzol receive their documented burden at the outgoing gate. Their receiving datasets begin at the same physical state and amount. Do not simultaneously give avoided-product credit and partition the same shared burden; any substitution study is a separate declared scenario.	jrc-iron-steel-coking-2013

System boundary rules · 5

Rule ID	Applies to	Rule	Source IDs
`boundary_route`	coking_plant	Confirm the actual site route against the cited manufacturing descriptions and a site diagram. Wet quench excludes a dry-quench gas loop and dry-quench recovered steam/electricity credit. Coal pretreatment includes actual crushing/blending/handling; purchased coal washing is upstream unless physically included and separately collected.	jrc-iron-steel-coking-2013, epa-coke-production-2008
`boundary_gas`	coking_plant	Include actual gas primary cooling, tar separation, ammonia-sulphate recovery, final cooling, selected wash-oil light-oil recovery and installed absorption/stripping desulphurisation. Keep their measured configuration; BREF alternatives do not license mixing unrelated scrubbers/catalysts. Exclude downstream chemical refining at the outgoing gate.	jrc-iron-steel-coking-2013, epa-coke-production-2008
`boundary_interfaces`	coking_plant	The aggregate foreground retains stage measurements and equal internal links for hot coke, raw/clean gas, condensate, flushing/quench liquor, tar residue and lean/rich wash oil. Internal transfers cancel only in the aggregate external-exchange table; do not erase them from the physical process graph or charge a second upstream dataset. Imported versus internally generated heat/gas and flare feed are separately reconciled.	jrc-iron-steel-coking-2013
`boundary_water_emissions`	coking_plant	Collect quench/cooling net make-up, recycle, evaporation, coke water, bleed and recipient returns independently. Include actual abatement and on-site effluent treatment. Treat externally transferred wastewater as a waste exchange; only actual environmental discharge after the selected treatment endpoint is an elementary emission. Document cooling configuration and abnormal bypasses.	jrc-iron-steel-coking-2013
`boundary_upstream`	coking_plant	Link each external input to an applicable upstream dataset with independently verified quantity/supply basis. Include actual start-up, shutdown, flaring, off-spec handling and maintenance in the campaign. Disclose initial capital construction and any separately reported transport; no unsupported infrastructure lifetime or exclusions hidden in a yield factor.	jrc-iron-steel-coking-2013

Validation rules · 6

Rule ID	Applies to	Rule	Source IDs
`validate_reference`	coke_dispatch	Require exactly one accepted final product reference with 1 kg as-received net coke, and identical bilingual denominator, aggregation and formula. Do not hide a verified intermediate UUID or add a fabricated identity to bypass reference checks.
`validate_route`	coking_plant	Check coal-coke manufacturing and wet-quench route, actual gas treatment connectivity and supply boundaries; reject petroleum-coke or dry/non-recovery route mixing and unreviewed chemical substitutions.	jrc-iron-steel-coking-2013, epa-coke-production-2008
`validate_balances`	coking_plant	Require source-bound whole-plant and stage mass/C/H/O/N/S/water/energy ledgers before allocation, paired internal links and independently justified residual uncertainty. No generic complete closure tolerance or per-coke recipe is assumed. Missing balances make the concrete dataset incomplete.	jrc-iron-steel-coking-2013
`validate_pollutants`	coking_plant	Check outdoor air/water versus resource/waste identity, each species/CAS, fossil origin where specified and reference property/unit. Preserve NOx quantity-definition uncertainty separately from identity; exclude N2O from NOx. Do not sum nested PM ranges or compound/total indicator duplicates. Biogenic CO2, if actual biogenic carbon is introduced under a reviewed extension, remains in the LCI irrespective of GHG reporting conventions.	jrc-iron-steel-coking-2013, epa-coke-production-2008
`validate_allocation`	coking_plant	Confirm each genuine external co-product, direct/shared burden split, matched revenue basis if used and conservation of allocated burden. Preserve physical output amounts and receiving gates without allocation-share scaling. Unresolved zero/negative values, absent prices or causal basis require review.
`validate_readiness`	coking_plant	Before using a concrete dataset, resolve all actually applicable empty identities and all supplier quantity/compartment debts, retain missing-data findings and uncertainty. Method compilation/measurement checks do not constitute scientific acceptance, a site survey or validation of an authored dataset.
