Anthraquinone-process hydrogen peroxide aqueous solution

1. Scope and Applicability

This PCR addresses industrial aqueous hydrogen peroxide manufactured by the alkylanthraquinone autoxidation (AO) cycle, from reagent/utility receipt through purification, any required concentration or dilution, storage and bulk dispatch. The executable reference is a nominal 30% by-mass aqueous grade. The category identity concerns the manufacturing route and aqueous peroxide, rather than the customer use or classification label. Other concentrations require verified concentration-specific reference identities and matching quantities before using this implementation; they do not automatically justify a new PCR. [jrc-lvoc-hydrogen-peroxide-2017; evonik-hydrogen-peroxide-brochure]

Exclude phosphides, carbides, hydrides, nitrides, azides, silicides, borides, organic peroxides, direct hydrogen/oxygen synthesis, electrochemical manufacture, formulated cleaning/disinfection blends and downstream peroxide use. Pharmaceutical/electronic/propellant certification is outside the ordinary industrial-grade implementation. The BREF is a 2017 EU large-volume continuous-production reference; its legal capacity scope, historic cases, plant-specific data, operating settings and BAT applicability conditions are not universal recipes, emission factors, yields, purities or energy defaults. This PCR contains inventory and measurement requirements, not synthesis or operating instructions.

Declare all required qualifiers in dataset metadata or equivalent process/product records. This is a declared mass reference, not a universal comparison of bleaching/disinfection performance. The solution includes active peroxide, carrier water and any verified additives; a concentration figure does not specify quality or manufacturing energy. The selected flow declares a primary Mass coefficient of 1.0 and a 30% aqueous identity; this coefficient is not an assay or a provider-process quantity convention. Confirm the actual lot CoA, weight-percent convention and net weighing record. For every linked supplier or consumer interface, document whether the native process exchange is kg complete solution or kg active H2O2. An active-only amount equals the sum of actual lot solution masses times their measured peroxide fractions; it cannot be linked as the same numerical quantity of whole solution. A generic peroxide flow without concentration cannot prove a 30% whole-solution interface, and a 50% textile-mill supply retains its concentration, location and receiving interface. Customer use examples do not restrict this reference to textile bleaching. [evonik-hydrogen-peroxide-brochure; jrc-ilcd-general-guide-2010]

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
mu_solution	peroxide_product	Mass	kg	Define Q as the sum of measured net masses of accepted complete solution lots produced over the matched period, counting each accepted lot once. Reconcile production, dispatches, opening/closing finished-product stocks, rejection and rework; exclude purchased same-category material from new synthesis and avoid counting reworked lots twice. Every inventory row uses per 1 kg reference flow. Active mass A = sum(lot solution mass × lot w); carrier water W = sum(lot mass × (1 − w − a)). Verify non-overlapping measured fractions and their mass closure. A and W are composition accounts, not additional reference-product outputs.
mu_solution_inputs	aqueous chemical inputs	Mass	kg	Record full supplied solution and its measured assay separately; convert active-only supplier data only with declared concentration, water and background boundary. Do not add carrier water twice.
mu_circulation	working solution and catalyst	Mass	kg	Keep opening/closing component stocks, receipts, external recovered returns, exports, degradation, internal circulation and measured losses separately. Internal recovery does not create a negative external input or eliminate actual losses.
mu_gases	gas exchanges	Mass / Volume	kg / m3	Gas volume needs stated T, absolute P, humidity, composition and compressibility plus provider reference conditions; derive mass from measured or supplier-verified conditions. No database secondary coefficient is assumed to be density.
mu_energy	electricity_in; steam_in	Net calorific value / Mass	MJ / kg	Electricity: measured kWh × 3.6 = MJ in the verified energy unit group; the native NCV label does not describe combustion of electricity. Steam kg, state enthalpy and provider heat reference remain separate. Derive ordinary-water enthalpies from measured absolute P, T and phase/dryness with a traceable IAPWS-IF97 implementation inside its validity domain. Saturation P/T alone does not establish wet-steam dryness. Account for every condensate/vent/drain/export and energy stock change; agree the heat-control boundary and losses. Neither NCV nor GCV in a native energy property proves net delivered steam heat. [iapws-if97-2012]
mu_emissions	air/water species	Mass	kg	Integrate species concentration × compatible gas/liquid flow × duration across matched periods. FID mg C is not kg of any specific solvent without speciation and an explicit carbon-to-species conversion. COD/TOC are treatment indicators, not automatically species emissions; avoid duplicate total/component loads.
mu_input_attribution	product inputs	Mass / Volume / Energy	row unit	Use the named protocol to reconcile physical receipts, store and in-use stocks, stage issues and unused returns before deriving the matched-period input numerator. Record actual service-life attribution for catalyst, adsorbent, filter, reusable container and maintenance supplies separately from full physical quantities and from co-product burden allocation. Do not divide an unadjusted purchase invoice by Q. [jrc-ilcd-general-guide-2010]
mu_species_balance	p_ao	Mass	kg	Maintain whole-phase mass and each molecular species ledger separately. Species can form or be consumed; H2O2 is not conserved through synthesis or decomposition. Reconcile conserved elemental C/H/N/O and other actual elements from verified molecular formulas and measured mixture fractions. Account for H2, O2, N2, carrier water, dissolved gas, steam/condensate, net reaction-formed or consumed water and all physical fates. No default yield, excess-air fraction, peroxide destruction fraction or decomposition rate is supplied.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Actual received hydrogen, declared working-liquid make-up components, catalysts, water and utilities with upstream production evidence
starting_condition_role	foreground_start
product_classification_scope	AO peroxide subset of CPC34280; not all chemicals under the leaf
recursive_input_rule	Purchased peroxide or externally processed same-category solution needs a verified upstream dataset; never model its manufacture as zero or count it again as new synthesis
upstream_dataset_requirement	Compatible route, grade, concentration/reference quantity, geography/year, utility state and waste treatment for every supplied/received exchange
disclosure	Actual process graph, control volumes, supplier boundaries, internal reuse, effluent destination, recovery, exclusions and missing identity/quantity links

rule_id	applies_to	rule	source_ids
sb_ao	p_ao	Include the actual hydrogenation/oxidation/extraction loop, working-solution drying/reversion, catalyst recovery, purification, any concentration/dilution and stabilisation, storage/dispatch, cooling and emission control. Stage meters and physical transfers must remain available even with the combined foreground unit.	jrc-lvoc-hydrogen-peroxide-2017; evonik-hydrogen-peroxide-brochure
sb_utilities	p_ao	Purchased water, compressed air and steam link to upstream supply; site generation requires separate real inputs and emissions. This implementation assumes externally supplied steam and no on-site combustion. A combustion route needs a separately evidenced utility module, each fuel and every relevant elementary emission before dataset completion.	jrc-lvoc-hydrogen-peroxide-2017
sb_destination	p_ao	Separate external waste transfers from direct emissions after included treatment. Record phase separation, recovered organic phases, water reuse and actual residual discharge. Extend the treatment unit with its own atomic reagents, energy, sludge and emissions when treatment is on site; do not hide it inside a removal-efficiency assumption.	jrc-lvoc-hydrogen-peroxide-2017
sb_actual_recipe	p_ao	The listed quinone, solvent and treatment-agent alternatives are conditional accounting examples, not a prescribed working-liquid formulation. Before completeness, add one atomic row for each actual stabiliser, additional carrier/solvent, catalyst support supply, cooling chemical, cleaning chemical, packaging component, waste and emitted species not represented here. Verify their physical identities and amount bases. Bulk dispatch excludes container tare from product mass; packaging and transport are added if inside the declared boundary.	jrc-lvoc-hydrogen-peroxide-2017; evonik-hydrogen-peroxide-brochure

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
p_ao	Integrated AO peroxide solution manufacture and bulk dispatch	required	Verified AO route and selected 30% aqueous grade	foreground	peroxide_product

Physical graph: reagent receipt → hydrogenation → oxidation → water extraction → purification → actual concentration/dilution and stabilisation → storage/dispatch. The extracted organic working phase returns through drying/reversion to hydrogenation; catalyst capture returns catalyst internally where applicable. Condensers/adsorbers recover solvent and condensate; external losses and treatment transfers remain visible. Keep each internal link at the same quantity at its sending and receiving ends. These stages are metered within p_ao so intermediate and finished peroxide do not create two reference-UUID product outputs.

For each stage, retain the measured whole working-liquid phase and its component composition as linked physical records. Record each actual added anthraquinone, hydroquinone make-up, solvent and stabiliser as its own atomic exchange; a working-liquid total is not one pure ingredient or an undocumented background recipe. Follow individual recovered organic fractions, aqueous fractions, interfacial rag, purge, degradation products and residues to internal reuse, stock, external recovery, waste or actual receiving compartment. A purchased formulated catalyst or genuinely supplied mixture retains its whole supplied identity and component assay; component accounting must not duplicate its upstream acquisition. Internal recovered material is a transfer, while actual external recovered supply or sale requires a distinct qualified exchange and provider/receiver boundary.

Process air and reagent hydrogen are whole supplied carriers with measured humidity and impurities; do not equate their quantities to dry O2 or pure H2 species. Decompose them only in the physical component ledger and, where appropriate, elementary resource/emission rows, without duplicating the purchased carrier background. Dissolved gas in working liquid and product, aerosol water, condensate stocks and returned water remain in the same-period mass/element accounts. Actual CO2, CH4 and other carbon-containing releases retain species and fossil/biogenic producer origin even when a chosen impact method does not characterize them. Add an atomic exchange for each actual container/packaging material, cleaning/passivation chemical, maintenance consumable and purchased service within the declared boundary, using its real quantity unit and service log; packaging tare, catalyst kg and service-hours are different quantities.

Inputs

Product flows

Hydrogen gas (hydrogen_in)

Purchased reagent hydrogen: retain actual producer, purity, impurities, moisture and supply route; recycled or dissolved hydrogen is tracked internally. A coal-based methanol-to-ethylene product identity is eligible as an input supplier only when the actual producer and that hard route are documented, with a matching kg-H2 or whole-gas convention, gas state and upstream boundary. It is not this peroxide output reference or a generic hydrogen substitution. No producer route is chosen merely because a native record exists.

Alternating current (electricity_in)

Only the native CN 1–35 kV grid-average consumption mix delivered to the user.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
al_physical	p_ao	Retain unallocated physical material, water, hydrogen/oxygen and solvent-component balances independently of allocated environmental burdens. Internal recycle is not a saleable co-product. Never multiply measured physical outputs by an allocation share.	jrc-lvoc-hydrogen-peroxide-2017
al_shared	p_ao	Use measured stage/campaign consumption and subdivision to avoid allocation of shared utility and treatment burdens where possible. Any remaining allocation must follow the declared study goal and modelling framework, demonstrate determining physical causality where available, document other justified criteria when it is unavailable, measured shares summing to one and sensitivity. A generic mass, sales-price or stoichiometric share is not supplied by this PCR. Physical amounts remain unallocated.	jrc-ilcd-general-guide-2010
al_recovery	p_ao	A saleable recovered solvent, catalyst metal or exported useful heat needs measured quality, receiver demand and a compatible treatment boundary. Resolve multifunctionality under the declared goal and modelling framework, with subdivision first where applicable; allocation and system expansion are not free interchangeable choices. Demonstrate actual substitution and uncertainty when system expansion is justified. Do not combine a recovered-material credit with a second avoided-treatment credit for the same operation. Waste destinations alone establish no credit.	jrc-ilcd-general-guide-2010

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_normalise	all inventory rows	inventory amount = matched-period protocol numerator / Q; Q is the accepted complete solution mass in kg from cp_product. Inputs use protocol stock/service attribution where applicable, while external output/resource quantities retain the matched physical boundary. Reference product output = 1 kg. Use row numerator units unchanged and retain the unallocated physical ledger.	cp_product; row collection protocol	row unit per 1 kg reference flow	jrc-ilcd-general-guide-2010; evonik-hydrogen-peroxide-brochure
calc_composition	peroxide_product	A = sum(m_lot × w_lot); W = sum(m_lot × (1 − w_lot − a_lot)); additives/impurities = sum(m_lot × a_lot). Check their sum against complete solution mass before allocation. Concentration-weighted active-normalised supplementary burdens use A, explicitly separated from the mandatory Q-based inventory.	cp_product	separate active/water/additive physical accounts	evonik-hydrogen-peroxide-brochure
calc_component_balance	quinone_in; xylene_in; phosphate_in; catalyst_in	opening component stock + external receipts + actual formation = closing component stock + external transfers + measured emissions + measured conversion/destruction; internal transfers cancel at the aggregated boundary. Record gross circulation separately. Replenishment alone is not total solvent emissions.	cp_materials; cp_waste; cp_air; cp_effluent	component residual and documented uncertainty	jrc-lvoc-hydrogen-peroxide-2017
calc_energy	electricity_in; steam_in	Electrical energy (MJ) = measured kWh × 3.6. Only for a mass-matched indirect circuit with no stock change, other outlets or work, delivered heat (MJ) = sum(m × (h_steam − h_condensate)) / 1000 minus measured boundary heat loss, with kg and kJ/kg. Otherwise close the full measured energy balance with all inlet/outlet enthalpy, energy stocks, work and relevant kinetic/potential terms before deriving heat. Actual wet-steam enthalpy = (1 − dryness) × saturated-liquid enthalpy + dryness × saturated-vapour enthalpy at the measured saturation state. No fixed steam-to-MJ factor or GCV/NCV equivalence is provided.	cp_energy	separate electricity MJ, steam kg and verified delivered heat MJ	iapws-if97-2012; jrc-lvoc-hydrogen-peroxide-2017
calc_emission	air and freshwater outputs	Species mass = sum(compatible species concentration × matched volumetric flow rate × interval duration), with concentration converted to kg/m3 and flow/time in compatible units and the same wet/dry and temperature/pressure basis. Use sufficiently resolved time integration when concentration or flow varies. Equivalently use the interval flow-weighted concentration × measured interval volume, without multiplying duration again. Reconcile point sources, fugitive sources and treatment residuals without duplicating captured/reused material or total-C indicators.	cp_air; cp_effluent	kg per species and receiving compartment	jrc-lvoc-hydrogen-peroxide-2017
calc_species_elements	p_ao	For species i: opening + external input + actual formation = closing + external output + actual consumption; internal transfers cancel. For a conserved element e: opening elemental mass + external elemental input = closing elemental mass + external elemental output, using verified formula fractions and measured mixture composition. Total physical mass has no reaction generation/destruction term. Track peroxide synthesis, degradation, decomposition and net water formation/consumption explicitly; stoichiometry describes an evidenced reaction extent, never an assumed plant yield or destruction fraction.	cp_balance; cp_product; cp_materials; cp_gases; cp_water; cp_waste; cp_air; cp_effluent	separate molecular, elemental and whole-mass residuals with uncertainty	jrc-lvoc-hydrogen-peroxide-2017; evonik-hydrogen-peroxide-brochure; jrc-ilcd-general-guide-2010

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	all inventory rows	Verify name, CAS where relevant, full qualifiers, route, reference property and provider quantity separately. Blank UUID means pending identity; a successful search does not establish background dataset compatibility.	actual direct record and supplier metadata
dq_mass	p_ao	Reconcile solution composition, water, H/O and each actual solvent/carrier component; retain unexplained residual with uncertainty and investigated causes, not a balancing fabricated exchange.	cp_product; cp_materials; cp_gases; cp_water
dq_completeness	p_ao	A conditional row may be absent only with actual route evidence. Missing stabiliser, treatment reagent/sludge, other working-liquid species or event emissions requires atomic extensions and blocks a complete dataset.	actual recipe/CoA, process graph and monitoring coverage
dq_time	all inventory rows	Match production, utilities, material replacement, waste and emission records; document period/service-life attribution, analytical detection limits, missing data and uncertainty. No historic BREF amount is a gap-filling default.	original collected records and uncertainty report

9. Validation Rules

rule_id	applies_to	rule	source_ids
val_reference	peroxide_product	Require exactly one linked reference-product output, full solution mass, nominal 30% grade and actual assay/acceptance. Active-only mass or unverified route/grade identity fails applicability.	evonik-hydrogen-peroxide-brochure
val_denominator	all inventory rows	Require positive Q and per 1 kg reference flow in inventory, protocol aggregation and bilingual rules. Any supplemental per-active-kg result must disclose A and is not the mandatory reference inventory.	evonik-hydrogen-peroxide-brochure
val_balance	p_ao	Check unallocated physical balances and same-quantity internal transfers before burden allocation; retain losses, water retained in solution, degradation and actual emissions. Do not assume theoretical stoichiometry is measured yield.	jrc-lvoc-hydrogen-peroxide-2017
val_species	p_ao	Check elementary species, origin, medium/submedium and mass definition. Outdoor unspecified air identities are not indoor or long-term flows; freshwater discharge is not water extraction. Retain biogenic CO2/CH4 if present with separate origin-specific rows regardless of a chosen GHG reporting convention. Do not combine nested particulate fractions or total/component emissions.	jrc-lvoc-hydrogen-peroxide-2017
val_readiness	all inventory rows	Unresolved identity, provider quantity, recipe, steam enthalpy or treatment/monitoring coverage is explicit incompleteness for the affected dataset. This authored method does not establish scientific approval or approve substituting incompatible UUIDs.	jrc-lvoc-hydrogen-peroxide-2017; evonik-hydrogen-peroxide-brochure
