Division 31Production of carbamide (urea)

### Division 31—Production of carbamide (urea) 331 (1) The production of carbamide (urea (CO(NH2)2)) is the chemical transformation of carbon dioxide (CO2) and anhydrous ammonia (NH3) to produce carbamide solution (urea (CO(NH2)2(aq))) that: (a) has a concentration of carbamide (urea (CO(NH2)2)) of at least 80%; and (b) is subsequently used to produce either or both of: (i) carbamide solutions (urea (CO(NH2) 2(aq))); and (ii) granulated, prilled or other solid forms of carbamide (urea (CO(NH2) 2(s))) of saleable quality; conducted in accordance with the following overall chemical equations: 2NH3(l) + CO2(g) → H2NCOONH4(aq) H2NCOONH4(aq) → H2NCONH2(aq) + H2O(l) (2) The production of carbamide (urea) is specified as an emissions‑intensive trade‑exposed activity. (3) The production of carbamide (urea) is a moderately emissions‑intensive activity. > Note: See Part 4. (4) The basis for the issue of free carbon units for the production of carbamide (urea) is by a tonne of 100% equivalent carbamide (urea (CO(NH2)2)) on a dry weight basis that is: (a) contained within either of the following products: (i) carbamide solutions (urea (CO(NH2)2(aq))); (ii) granulated, prilled or other solid forms of carbamide (urea (CO(NH2)2(s))) of saleable quality; and (b) produced by carrying on the emissions‑intensive trade‑exposed activity; and (c) of saleable quality. > Note: Saleable quality is explained in Part 2.
