Ammonium nitrate and calcium ammonium nitrate by neutralisation of nitric acid with ammonia
Sourced conceptual inventories per tonne of solid ammonium nitrate and per tonne of calcium ammonium nitrate (about 27 % N, limestone filler): feeds from stoichiometry with sourced losses, utilities and emissions from EU LVIC-AAF BREF chapter 9. No flowsheet; not reviewed.
Overview
- Capacity
- per tonne of product (each dataset's basis); no plant size
What goes in and out
In
- AmmoniaFeedstocklinked to ammonia-1 (lca/mappings.yaml)
- Nitric acidFeedstock60 wt% acid by mass of solution, linked to nitric-acid-1 (lca/mappings.yaml)
- LimestoneFeedstockCAN filler only, taken as pure CaCO3 (ASSUMED)
Out
- Ammonium nitrateMain productdataset ammonium-nitrate-pressure-neutralisation-solid
- Calcium ammonium nitrateMain productdataset calcium-ammonium-nitrate-granulation
- WaterEmissionthe acid's water as vapour (ASSUMED residual of the water balance)
- WastewaterWaste
Utilities: Electricity, Steam (imported steam by mass; the source states no pressure for these ranges)
Life cycle assessment

In the LCI database: system model, datasets and KPIs against the benchmarks
In the LCI database
- Status
- Preliminary 2 unmapped exchanges. Some exchanges have no background mapping yet: they are exported unlinked and count no burden, so the inventory is incomplete.
- System model
- attributional, cut-off (methodology 1.1.0)

KPI benchmark positions
| KPI | Value | Reference range | Position |
|---|---|---|---|
| Ammonia consumption per t of ammonium nitrate | – t/t | 0.213 to 0.213 t/t | not evaluated |
| Electricity per t of solid ammonium nitrate No open source independent of the dataset found (2026-11-06). The open figure for solid AN is the EFMA (2000) range for a new AN facility, 25 to 60 kWh/t, in LVIC-AAF BREF Table 9.3, p. 370, and the dataset takes its midpoint, so a range made of it would only check the transcription. Table 9.8 (p. 378) gives electricity for the AN solution section only, not for solid AN. US EPA AP-42 section 8.3 and its background report give emissions only. | – kWh/t | not available | not evaluated |
| Nitric acid (as 100 % HNO3) consumption per t of ammonium nitrate | – t/t | 0.789 to 0.789 t/t | not evaluated |
| Steam imported per t of solid ammonium nitrate No open source independent of the dataset found (2026-11-06). The open figure for solid AN is the EFMA (2000) range of 0 to 50 kg/t in LVIC-AAF BREF Table 9.3, p. 370, and the dataset takes its midpoint, so a range made of it would only check the transcription. Table 9.8 (p. 378) gives the steam balances of the neutraliser types, not the import of a solid AN plant. | – kg/t | not available | not evaluated |
| KPI | Value | Reference range | Position |
|---|---|---|---|
| Electricity per t of calcium ammonium nitrate | – kWh/t | 13.2 to 13.2 kWh/t | not evaluated |
| Steam per t of calcium ammonium nitrate | – kg/t | 13 to 13 kg/t | not evaluated |
Maturity and review
Design maturity Concept (claimed): An idea or first flowsheet; numbers are rough. No independent engineering review yet. Automated checks passing is not a review.
Calculation maturity, from the checked evidenceNot assessed
The process has no maturity report (cheme maturity, checks/maturity.json), so no calculation maturity is established.
cheme maturity --write.Artifact completeness
Which deliverables exist. They never raise a calculation maturity level: a drawing from unchecked numbers is still unchecked.
Not reported without a maturity report.
Independent review
Not independently reviewed
No independent engineering review yet. Automated checks passing is not a review.
Set by people only. Reaching a calculation maturity level or passing automated checks is not an independent review or an approval.
