Ammonium nitrate and calcium ammonium nitrate by neutralisation of nitric acid with ammonia

Overview

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.

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

Utilities: Electricity, Steam (imported steam by mass; the source states no pressure for these ranges)

KPI benchmark positions

KPIValueReference rangePosition
Ammonia consumption per t of ammonium nitrate– t/t0.213 to 0.213 t/tnot 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/tnot availablenot evaluated
Nitric acid (as 100 % HNO3) consumption per t of ammonium nitrate– t/t0.789 to 0.789 t/tnot 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.

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.

No level shownThe design maturity (Concept) is the manifest's claim, not evidence. A level appears here once the process's repository holds a current report from 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.
