1. Scope and Applicability

This method covers refinery gas-separation or liquid refinery-component blending/supply routes for fossil commercial propane, specified butane grades and composition-defined LPG blends at one industrial bulk liquid delivery gate. It starts with actual burden-bearing raw gas, mixed natural-gas liquids, refinery gas/liquid fractions or purchased liquid blending components. Use the gas-recovery and refinery submodels already supporting that feed, extending only the actual separation, final treatment, blending, liquid storage and loading operations. A fractionation co-product is not justification to recreate an entire gas field or refinery. Do not impose a fractionation step on an actual component-blending terminal. ref-bref-2015, eia-propane-2023, eia-storage-2026

Exclude standalone natural-gas fractionator finished-product reference bindings, LNG, gaseous propane/butane delivery, olefin-rich propane/propylene or butylene products, extraction, refinery cracking/reforming manufacture, high-purity analytical/refrigerant certification and customer combustion. Bulk liquid may be pressurised, refrigerated or both; a gaseous cubic metre, refrigeration-circuit propane charge or unseparated Y-grade is not the delivered liquid reference product. No universal composition, purity, pressure, temperature, recipe, yield or emission factor is prescribed. The data producer must select one physically verified product identity before using this method.

Natural-gas-derived feeds enter only where actually received by this refinery or refinery-component supply unit; reuse upstream gas-recovery/treatment methodology once. That feed origin does not automatically place a standalone natural-gas fractionator within this reference binding.

Declare every qualifier in dataset metadata or reference-flow comments. The reference mass property/unit group are verified native links for the representative LPG flow; actual provider quantities, composition/grade and liquid-gate compatibility still require dataset-specific collection.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	final_product	Mass	kg	D is positive accepted net whole liquid product mass for the same SKU, route, site and period, collected using cp_final_product; every row uses per 1 kg reference flow. Include accepted contained water, odorant and other additives in D; D is not dry hydrocarbon mass. Exclude packaging, container tare and duplicate internal handoffs. Reconcile actual returns, heels and stock changes without subtracting a return twice.
liquid_volume	final_product, blend_propane, blend_nbutane, blend_ibutane	Mass	kg	Obtain liquid mass by calibrated mass metering or m_liquid=V_liquid*rho_liquid(T,P,x), with measured liquid volume, temperature, absolute pressure and composition-compatible density. Gas volume cannot directly represent liquid product quantity; unknown liquid density/state remains unresolved.
gas_volume	raw_gas, refinery_gas, residue_gas, fuel_gas	Volume	m3	Keep raw gas volume wet/dry basis and metered/reference T/P. Convert using m_gas=P_absV_gasMW(x)/(ZRT) in consistent units, or matching measured gas-phase density. Match provider/background m3 definition; a database secondary mass factor is not gas density.
steam_heat	steam, condensate_return	Energy	MJ	Record steam and returned condensate using actual mass, pressure, temperature, quality and enthalpy. Net delivered heat=m_inh_in-m_returnh_return with declared enthalpy datum, other losses and boundary. Steam mass or an MJ property alone does not establish net delivery basis.
utilities_active	electricity, mea, teg, caustic, odorant	Declared row property	MJ; kg	Preserve actual electricity reference property; 1kWh=3.6MJ. Input flow quantity is delivered-grade product mass. Active substance mass=m_product*w_active; retain carrier water/contaminants in the physical ledger, without an additional purchased-water exchange for contained water. Do not treat wet solution as pure chemical. No default concentration or quantity.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Burden-bearing gas/liquid feed at an existing submodel interface or purchased liquid blending components
starting_condition_role	Supplied feed; no repeated resource extraction or whole refinery
product_classification_scope	Fossil commercial liquid propane; specified n-butane/isobutane grade; composition-defined propane-butane LPG blend
recursive_input_rule	Purchased same-category components link complete supplier/gate datasets; internal recycling retains matched endpoints without another purchase or credit.
upstream_dataset_requirement	Actual gas/refinery feed, blending component, utility, material, infrastructure and waste-management interfaces and burdens; disclose missing coverage.
disclosure	site and production period; one SKU and commercial grade; propane/n-butane/isobutane assay and olefin impurities; purity; water and sulfur; fossil origin; raw-feed sources and upstream gates; recovery/separation or purchased-component blending route; liquid phase at transfer; mass meter or liquid density and measured volume; temperature and absolute pressure; gas-volume wet/dry and reference conditions with compressibility; storage and loading vapour destination; utilities and steam-return basis; co-products and allocation; gate and transport scope

rule_id	Applies to	Rule	source_ids
boundary_existing	all operations	Start at the disclosed gas/liquid inlet to the existing recovery/fractionation submodel. Preserve supplier extraction/refinery conversion burdens, feed provenance and all upstream gas/liquid/solid co-products (including coke where applicable) in their original physical ledger; do not delete or duplicate them. Shared treatment, sulfur recovery, wastewater management and energy systems must have one owner. An integrated site may expose the shared physical submodel and operation-level allocation; a standalone terminal links qualified upstream datasets.	ref-bref-2015; epa-gas-processing-1995
boundary_stages	lpg	Declare reception, actual cooling/absorption, de-ethanising, depropanising/debutanising/isomer separation, actual sweetening/drying, blending, odorisation, liquid storage and closed-loop loading/vapour handling stage meters. Their sequence is site-specific. Aggregate them as one LPG foreground unit; cancel internal same-material links with identical endpoint quantities, while retaining stage mass/energy observations. No additional finished-reference output at a storage/packaging handoff.	ref-bref-2015; eia-storage-2026
boundary_vapour	lpg	Distinguish recovered vapour recycled internally, gas sent to an existing fuel header, gas transferred to external treatment, vented species and flare/combustion exhaust. Measure the actual recovery and destruction state; never classify all displaced LPG vapour as emitted or assume complete combustion. Refrigeration-circuit losses are tracked independently from product losses.	ref-bref-2015; epa-gas-processing-1995
boundary_energy	lpg	Record electricity, imported steam, fuel and each actual refrigerant separately. Recovered upstream reboiling heat retains its heat interface and prior burden; it is not free steam. Imported steam is distinct from foreground boiler fuel and exhaust. Include actual refrigeration/cooling, wastewater and spent adsorbent handling. Actual additional chemicals, refrigerants, packaging, wastes and releases each require their own atomic exchange before dataset completion. A background link must cover the entire actual operation and upstream burdens; record its gate, period, composition/state and coverage. A cutoff needs a documented rationale, omitted burdens and sensitivity; missing quantities never become zero, and paired physical pipes remain in the unallocated ledger.	ref-bref-2015
boundary_gate	lpg	The product gate is the documented liquid custody transfer, before customer vaporisation or use. Include on-site tank residence and loading losses through that gate; off-site shipping enters only if explicitly within the declared boundary and supported by its own submodel. Allocate infrastructure over actual lifetime throughput or justify exclusion and sensitivity. Bulk tank and pressure-container manufacture are not additional foreground production stages, but their service burdens remain attributable to LPG delivery: collect container/tank identity, material and tare, lifetime throughput or service cycles, repair/replacement, inspection, cleaning/hydrotest, coating, utilities, wastes and retirement. Include actual reusable-container return/empty handling within the gate, residual LPG and returned stocks. Link complete service datasets once; add an atomic exchange for each actual material, utility, waste or release they do not cover. Do not count the entire durable container mass as consumed per filling, assume unlimited reuse, or assign a default lifetime.	eia-storage-2026

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
lpg	Actual LPG separation or blending and liquid delivery	required	Actual declared site route; absent stages excluded with evidence	Foreground production with separate stage observations	per 1 kg reference flow

Stage ledger: inlet gas/liquid reception → actual treatment/fractionation → composition acceptance or blending → liquid tank → loading transfer. Purchased-component blending starts at component reception. Every internal link retains from/to, mass or composition/T/P-qualified volume, period and equal endpoint quantities. Mark circulating absorbent, refrigerant, recovered vapour, own-use fuel header and stocks separately. Do not add absent stages or upstream operations already counted.

Natural gas supplied for on-site LPG heating (`fuel_gas`)

Only external gaseous natural-gas fuel; retain provider m3 T/P, wet/dry composition and compressibility. A secondary mass factor is not density. Internal refinery gas diverted to own use remains in the physical ledger, not a second external purchase.

The native reference is Volume/m3, not Mass. Supplier reference T/P, wet/dry composition and compressibility must be compatible before linking background quantities; no secondary mass coefficient is treated as density.

Ethanethiol supplied for LPG odorisation (`odorant`)

Conditional only on actual ethanethiol (CAS75-08-1), with certificate, purity and dose records. Collect delivered whole product mass and actual ethanethiol fraction. A formulated odorant mixture requires a separate composition-qualified formulation exchange including its carriers; ethanethiol active mass does not represent the whole formulation.

Outputs

Product flows

Liquefied propane-butane product at the declared gate (`final_product`)

Exactly one selected saleable composition-qualified liquid SKU/grade per dataset. The representative LPG mixture UUID is not proof of a pure propane or pure butane identity; a distinct single-species SKU requires its own verified route/grade-compatible reference binding before dataset completion. Measure accepted whole net liquid mass D including accepted contained water and additives, excluding packaging and tare. Record dry hydrocarbon mass only as a derived composition quantity. Stage intermediates are not additional reference outputs.

The representative UUID is refinery LPG supply at an industrial gate. Require an actual liquid commercial C3/C4 product and composition/grade acceptance; no database calorific value or generic density is a foreground quantity.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_hierarchy	shared burdens	First subdivide by actual metered operations or assess a documented expanded system. For unresolved shared burdens, use a demonstrable causal physical relationship; if unavailable, justify same-gate period-matched economic allocation and sensitivity. Do not infer a universal mass or heating-value share from the product label.	eu-pef-multifunctionality-2021
allocation_ledgers	all rows	Keep the unallocated physical process diagram and feed/product/total-mass/water/C/H/O/N/S/energy balances separate from the environmental burden account. Preserve co-product quantities, compositions, phases, receivers and stock changes. Multiply only shared burdens by accepted allocation factors; do not mechanically multiply physical co-product outputs by those factors. In the reference-specific result, selected product is 1 kg; all physical observations remain traceable by D.	eu-pef-multifunctionality-2021; ref-bref-2015
allocation_internal	internal links	Internal recycling of absorbent, refrigerant, vapour, gas fuel or condensate is recorded at both stage endpoints with matching quantities, but does not create a second external input or avoided-product credit. Own-use fuel is part of actual physical energy/carbon balance and its combustion has one owner. Waste disposal and flaring do not become saleable co-products.	ref-bref-2015; eu-pef-multifunctionality-2021

System boundary rules · 5

Rule ID	Applies to	Rule	Source IDs
`boundary_existing`	all operations	Start at the disclosed gas/liquid inlet to the existing recovery/fractionation submodel. Preserve supplier extraction/refinery conversion burdens, feed provenance and all upstream gas/liquid/solid co-products (including coke where applicable) in their original physical ledger; do not delete or duplicate them. Shared treatment, sulfur recovery, wastewater management and energy systems must have one owner. An integrated site may expose the shared physical submodel and operation-level allocation; a standalone terminal links qualified upstream datasets.	ref-bref-2015, epa-gas-processing-1995
`boundary_stages`	lpg	Declare reception, actual cooling/absorption, de-ethanising, depropanising/debutanising/isomer separation, actual sweetening/drying, blending, odorisation, liquid storage and closed-loop loading/vapour handling stage meters. Their sequence is site-specific. Aggregate them as one LPG foreground unit; cancel internal same-material links with identical endpoint quantities, while retaining stage mass/energy observations. No additional finished-reference output at a storage/packaging handoff.	ref-bref-2015, eia-storage-2026
`boundary_vapour`	lpg	Distinguish recovered vapour recycled internally, gas sent to an existing fuel header, gas transferred to external treatment, vented species and flare/combustion exhaust. Measure the actual recovery and destruction state; never classify all displaced LPG vapour as emitted or assume complete combustion. Refrigeration-circuit losses are tracked independently from product losses.	ref-bref-2015, epa-gas-processing-1995
`boundary_energy`	lpg	Record electricity, imported steam, fuel and each actual refrigerant separately. Recovered upstream reboiling heat retains its heat interface and prior burden; it is not free steam. Imported steam is distinct from foreground boiler fuel and exhaust. Include actual refrigeration/cooling, wastewater and spent adsorbent handling. Actual additional chemicals, refrigerants, packaging, wastes and releases each require their own atomic exchange before dataset completion. A background link must cover the entire actual operation and upstream burdens; record its gate, period, composition/state and coverage. A cutoff needs a documented rationale, omitted burdens and sensitivity; missing quantities never become zero, and paired physical pipes remain in the unallocated ledger.	ref-bref-2015
`boundary_gate`	lpg	The product gate is the documented liquid custody transfer, before customer vaporisation or use. Include on-site tank residence and loading losses through that gate; off-site shipping enters only if explicitly within the declared boundary and supported by its own submodel. Allocate infrastructure over actual lifetime throughput or justify exclusion and sensitivity. Bulk tank and pressure-container manufacture are not additional foreground production stages, but their service burdens remain attributable to LPG delivery: collect container/tank identity, material and tare, lifetime throughput or service cycles, repair/replacement, inspection, cleaning/hydrotest, coating, utilities, wastes and retirement. Include actual reusable-container return/empty handling within the gate, residual LPG and returned stocks. Link complete service datasets once; add an atomic exchange for each actual material, utility, waste or release they do not cover. Do not count the entire durable container mass as consumed per filling, assume unlimited reuse, or assign a default lifetime.	eia-storage-2026

Allocation rules · 3

Rule ID	Applies to	Rule	Source IDs
`allocation_hierarchy`	shared burdens	First subdivide by actual metered operations or assess a documented expanded system. For unresolved shared burdens, use a demonstrable causal physical relationship; if unavailable, justify same-gate period-matched economic allocation and sensitivity. Do not infer a universal mass or heating-value share from the product label.	eu-pef-multifunctionality-2021
`allocation_ledgers`	all rows	Keep the unallocated physical process diagram and feed/product/total-mass/water/C/H/O/N/S/energy balances separate from the environmental burden account. Preserve co-product quantities, compositions, phases, receivers and stock changes. Multiply only shared burdens by accepted allocation factors; do not mechanically multiply physical co-product outputs by those factors. In the reference-specific result, selected product is 1 kg; all physical observations remain traceable by D.	eu-pef-multifunctionality-2021, ref-bref-2015
`allocation_internal`	internal links	Internal recycling of absorbent, refrigerant, vapour, gas fuel or condensate is recorded at both stage endpoints with matching quantities, but does not create a second external input or avoided-product credit. Own-use fuel is part of actual physical energy/carbon balance and its combustion has one owner. Waste disposal and flaring do not become saleable co-products.	ref-bref-2015, eu-pef-multifunctionality-2021

Validation rules · 6

Rule ID	Applies to	Rule	Source IDs
`validate_reference`	final_product	Verify one selected saleable liquid product identity and one final_product output, 1 kg net reference, positive measured D, actual composition/purity and all qualifiers. An unresolved reference UUID or incompatible physical route/property/unit prevents a usable completed dataset. Do not reuse a gas/LNG reference or refrigerant circuit charge as LPG.	ref-bref-2015, eia-storage-2026
`validate_quantity`	all rows	Preserve raw mass/volume/T/P and conversion provenance. Gas and liquid volume bases remain separate; supplier/background reference bases must be independently compatible, not merely identity-matched. Steam pressure and enthalpy basis, active chemical fraction and electricity property must be established.	ref-bref-2015
`validate_balance`	lpg	Reconcile feeds, liquid and gaseous products, vents, flare carbon/sulfur, water, spent materials, own use and stock change before allocation. Retain residuals and meter uncertainty; no forced zero residual. Distinguish acid gas sent for sulfur recovery from air H2S; distinguish wastewater transfer from receiving-water emissions.	ref-bref-2015, epa-gas-processing-1995
`validate_carriers_services`	lpg	Check complete stage/background coverage, paired pipes, liquid/vapour inventories and returns; reconcile whole-carrier mass without adding constituent quantities twice. Require separate total mass, water, C/H/O/N/S and energy residuals. Check actual packaging and durable pressure-container/tank service life, maintenance, cleaning, return and retirement burdens with one owner and per-D service allocation; exclusions need evidence and sensitivity. A generic reference label or a matching unit cannot override conflicting source route, location, composition or grade.	ref-bref-2015, eia-storage-2026, eu-pef-multifunctionality-2021
`validate_species`	air emissions	Check actual species, fossil/biogenic origin, CAS where applicable, outdoor-air compartment/subcompartment and amount definition against the flow original. Never substitute nitropropane for propane, a correction flow for a pollutant, or a total VOC/NOx quantity for individual species. NO and NO2 cannot be duplicated with total NOx; NOx is not N2O. Preserve actual biogenic CO2 if an auxiliary biogenic fuel occurs, with its own added input/emission rows. Particulate bins must be disjoint with filterable/condensable definitions.	ref-bref-2015, epa-gas-processing-1995
`validate_complete`	dataset	Document performed/skipped checks, identity gaps, missing upstream burdens, measurements and provider bases. Actual MEA/TEG regeneration, sulfur recovery, on-site water treatment, other refrigerants or combustion engines require complete compatible submodels, including actual BTEX/isomers, N2O and other measured releases as atomic rows. Missing, unknown, measured zero and a measured nondetect with detection limit are different; conditional not-applicable status requires route evidence. Future collection requirements do not establish actual quantities or SKU acceptance. No historical/single-plant composition, utility ratio or factor establishes a general default.	ref-bref-2015, epa-gas-processing-1995
