Prilled hydrated calcium-nitrate/ammonium-nitrate double salt from nitrophosphate CNTH

1. Scope and Applicability

This PCR covers factory-gate manufacture of solid hydrated calcium-nitrate/ammonium-nitrate double-salt prills by melting nitrophosphate-derived calcium nitrate tetrahydrate (CNTH), neutralising residual acid with gaseous anhydrous ammonia, concentrating and prilling. The reference is a mass-defined intermediate industrial product, not equal agronomic performance. Use only when actual lot analysis confirms both nitrate salts and hydration; an ammonia-free calcium nitrate lot is outside scope. jrc-lvic-aaf-2007 §7.4.8/Table7.10 and §7.4.4 support this route; yara-calcinit-2023 provides one actual solid double-salt product, without setting this PCR recipe.

Exclude ammonium nitrate with calcium carbonate/dolomite or other inorganic filler (CPC34615), pure ammonium nitrate (34613), nitrate solutions as sold, dry blending, direct limestone/lime acid-neutralisation routes, pan granulation, micronutrient-enriched or intentionally coated grades, and downstream dissolution, transport to farms, application and use-phase emissions. An actual configuration needing an excluded operation requires a scoped method extension and its specific evidence before using this route. Brand, fertilizer grade and the name “calcium ammonium nitrate” alone cannot establish identity.

reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	1 kg accepted net as-delivered product; retain crystal and permitted free water. Collect accepted campaign mass P using cp_product; exclude sacks/pallets, recycle and rejected mass. Every row uses the same P.
material_basis	cnth_feed, ammonia_feed	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Keep delivered wet mass, dry salt, adhering liquor, free acid and active ammonia separate in cp_material. Assay times mass provides component ledgers; active mass cannot replace provider delivered quantity.
steam_basis	heat_input	Gross calorific value 93a60a56-a3c8-14da-a746-0800200c9a66	MJ	cp_heat must reconcile supplier GCV quantity with measured steam/return enthalpy, actual pressure and dryness. An MJ unit alone proves no net-heat equivalence. Missing supplier conversion means incomplete linkage, not zero heat.
nitrogen_species	ammonia_air, nitrate_water, ammonium_water	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Retain original mass-as-N or species basis, molecular/ion identity and conversion trace. Total N and nitrate aerosol N are balance diagnostics; do not duplicate them as extra species exchanges.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Measured CNTH crystals/entrained mother liquor and other inputs received at a defined foreground gate
starting_condition_role	Unit-process gate; upstream cradle burdens retained through linked suppliers
product_classification_scope	CPC:3.0:34614 narrower
recursive_input_rule	Actual purchased same-category double salt is an input only with supplier quantity/background and explicit rework scope; never count internal recycled fines as purchase or expand into infinite identical processes
upstream_dataset_requirement	CNTH upstream rock digestion/crystallisation and shared acid/ammonia burdens require traceable upstream datasets and documented co-production partition; CNTH is not assumed burden-free waste
disclosure	Declare origin, concentration/phase, lot, measured quantity, provider basis, shared-site interfaces and unresolved links; gate-to-gate records alone do not establish cradle-to-gate completeness

rule_id	applies_to	rule	source_ids
boundary_route	double_salt_manufacture	Include receiving/melting, ammonia vaporisation where needed, neutralisation, evaporation, prilling, screening, product acceptance, packing, recovery and ventilation within one foreground unit. Keep stages separately metered in cp_stage. jrc-lvic-aaf-2007 §§7.4.4/7.4.8.	jrc-lvic-aaf-2007
boundary_utilities	double_salt_manufacture	Link external electricity, industrial-boiler steam heat, water and waste treatment to their actual providers once. On-site combustion or biological/chemical effluent treatment requires separately evidenced operations and atomic fuel/reagent/emission rows before completeness can be claimed; it is not hidden in a heat or waste quantity.	jrc-lvic-aaf-2007; jrc-cww-2016
boundary_recycle	double_salt_manufacture	Record fines, oversize, scrubbed nitrate liquor and condensate internally with equal mass on each sending/receiving stage link and measured inventories. Only net external exchanges appear below. If material leaves the plant for a receiver, retain its real output identity and quantity.	jrc-lvic-aaf-2007; jrc-cww-2016

double_salt_manufacture	CNTH conversion and accepted prill delivery	required	Only qualified CNTH melt/ammonia/evaporation/prilling route	Integrated foreground unit; cp_stage preserves stage meters and internal links	finished_product; 1 kg

Stages: receipt/melt → neutralise → concentrate/steam recovery → prill/cool/screen → accept/package; gas scrubber liquor/collected fines/condensate return to their measured receiving stages. This aggregation avoids representing the same final reference UUID twice between finishing and packaging.

Process heat from steam (heat_input)

Only externally supplied industrial-boiler steam heat. Record pressure, temperature, dryness, mass, condensate return and supplier definition of the Gross calorific value/MJ reference. Independently reconcile delivered heat from inlet and return enthalpies.

Liquid water released to freshwater (water_freshwater)

Only carrier-water volume in an actual direct freshwater discharge, excluding separately measured solute mass. Use measured discharged carrier-water mass divided by measured density at stated temperature for a mass-to-volume conversion; bulk wastewater volume alone is not the pure carrier-water volume. Preserve physical water mass for the water balance. Externally treated wastewater is counted through its receiver instead. Database linkage remains pending.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_separation	double_salt_manufacture	Use an explicitly declared attributional LCI context, following jrc-ilcd-2010 §§7.9.2–7.9.3. Consequential questions need a separate goal/scope decision and cannot inherit this hierarchy automatically. Retain a physical unit/stage ledger before allocation. Separate shared-site utilities and upstream CNTH/NPK co-production using measured causal/subdivision evidence first. Receiving a separated CNTH stream never establishes zero upstream burden. Allocation convention and provider denominator must accompany its upstream dataset.	jrc-ilcd-2010; jrc-lvic-aaf-2007
allocation_burden	double_salt_manufacture	If subdivision fails, document the selected defensible physical relation; if none exists, disclose actual dated economic data and sensitivity. Calculate burden shares summing to one in a separate ledger. Never multiply real co-product output masses, elemental balances or internal link quantities by those shares. This is an attributional hierarchy based on jrc-ilcd-2010, not a BAT-prescribed allocation formula. Economic values must reflect the actual condition and gate where co-products leave co-production, not downstream packed/transported prices without adjustment.	jrc-ilcd-2010
allocation_recovery	double_salt_manufacture	Internal recovered salts/condensate are circulation, without extra product output or avoided-production credit. Discarded salt, sludge and wastewater retain actual receiver treatment. A genuinely sold recovered product requires demonstrated acceptance, composition and a separate verified identity before applying any allocation.	jrc-ilcd-2010; jrc-lvic-aaf-2007

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalise_campaign	all inventory rows	Exchange per reference kg = raw net campaign exchange total / accepted net product mass P, divided once. Sum raw quantities over the complete same route, hydration/specification and campaign, including attributable failed/zero-output intervals, starts/stops, cleaning and rework; do not average successful-interval ratios or divide a per-kg value again. P must be positive and is credited once after reconciling returns/reacceptance, finished stocks and work in progress. Preserve their production history and carried burdens so attribution covers the same accepted output; burden adjustments do not erase raw physical exchanges. Internal recycle remains outside the external numerator and is not a new accepted output. If P is zero, retain totals and disclose no unit result rather than divide or omit burdens.	cp_product; row-specific protocol	row amount per 1 kg reference flow	jrc-cww-2016
components_and_water	cnth_feed, finished_product	Component mass = measured delivered mass × measured component mass fraction. Maintain disjoint dry salt, crystal water, free water and adhering-liquor terms; no manufacturer assay transplanted.	cp_material; cp_product; cp_water	physical component/water ledger	jrc-lvic-aaf-2007
electricity_conversion	electricity_input	MJ = measured kWh × 3.6; the definition 1 kWh = 3.6 MJ is a unit conversion, not a technology consumption value.	cp_energy	provider-compatible MJ per reference kg
emission_load	ammonia_air, nitrate_water, ammonium_water, calcium_water	Species mass = sum over measured intervals of concentration × compatible gas/water flow × interval duration × explicit unit/species conversion. For mass-as-N multiply by molar mass of measured species / molar mass of N after confirming speciation.	cp_air; cp_effluent	physical species load then per-reference amount	jrc-cww-2016
particle_partition	pm_fine, pm_coarse, pm_large	Disjoint bins: fine = measured PM2.5; middle = compatible PM10 − PM2.5; large = compatible total PM − PM10. Independent disjoint tests may replace differences. Incompatible tests or negative differences require review, not clipping to zero.	cp_air	non-overlapping physical particle loads	jrc-cww-2016
heat_reconciliation	heat_input	Net delivered heat = measured inlet steam mass × inlet enthalpy − measured return mass × return enthalpy, using one explicit datum and appropriate pressure/temperature/dryness; reconcile other outlet/loss terms. The supplier GCV conversion is separate measured/declared evidence; no default GCV-to-net factor.	cp_heat; cp_stage	separate physical heat and provider reference ledgers	jrc-lvic-aaf-2007

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
identity	all inventory rows	Verify actual species/state, route, medium, property/unit and provider definition. Empty UUID or pending compatibility remains explicit; identity verification alone is not a complete background dataset.	supplier specifications, flow evidence, receiver criteria
balances	double_salt_manufacture	Reconcile unallocated mass, water, N and Ca, impurities/stock changes and stage links; state uncertainties and unresolved residuals. Never invent yield, purity, hydration or zero emissions to close balances.	cp_product; cp_material; cp_water; cp_stage
coverage	double_salt_manufacture	Capture normal and start/stop production, cleaning, leaks, recovery and each real waste/emission. Additional actual reagents, pollutants or utilities must be separate scoped rows with evidence; absent or unquantified rows cannot imply completeness.	jrc-cww-2016; cp_stage
sources	double_salt_manufacture	Historic BAT/CALCINIT case values do not define universal recipes, water removal, energy, emission factors or quality thresholds. Require current lot tests and supplier evidence; disclose modelling choices separately from external facts.	un-cpc-2025; jrc-lvic-aaf-2007; jrc-cww-2016; yara-calcinit-2023

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_product	reference product	Confirm both nitrate salts, solid hydration and the declared CNTH route; exactly one final reference output is 1 kg of net accepted product. Packaging, off-spec waste and internal intermediates do not add another reference output.	un-cpc-2025; jrc-lvic-aaf-2007; yara-calcinit-2023
validate_quantity	all inventory rows	All rows and collection aggregation use the same accepted net P and campaign; source/property/unit conversions and upstream CNTH allocation must be explicit. Undefined steam GCV/enthalpy conversion, missing quantities, uncertain speciation or missing exact identity remain findings and block complete dataset validation.	jrc-cww-2016; jrc-ilcd-2010
validate_no_overlap	double_salt_manufacture	Check equal internal links, stock changes, physical balances versus burden allocation, disjoint PM bins and total-N reconciliation. A transferred wastewater stream and its direct elementary pollutant load are mutually exclusive at this boundary; source case “no discharge” is not proof of actual absence.	jrc-cww-2016; jrc-lvic-aaf-2007

10. Published Dataset Profile

Field	Value
dataset_role	Foreground industrial double-salt manufacture; optional cradle-to-gate integration
downstream_use	Mass-based supplied fertilizer/chemical input with declared composition and hydration
allowed_use	Only qualified CNTH/ammonia/evaporation/prilling solid route; compatible provider bases
excluded_use	Other CAN identities/routes, solution reference, field-use efficacy or universal fertilizer recipe
required_metadata	Reference qualifiers; complete campaign P; provider and receiver identities/bases; stages and inventories; assays; allocation; emission compartments and methods
required_quality_disclosure	Actual measured versus modelled data; coverage/uncertainty; unresolved UUIDs and steam compatibility; upstream CNTH burden completeness; metadata debts
update_trigger	Change of CNTH origin, process route, hydration/assay, additive/coating, provider basis, abatement, waste receiver or shared-site allocation
