Method For the Production of Fertilizer and CO2

A method for the combined production of (i) a fertilizer selected from the group consisting of ammonium nitrate, ammonium phosphates or a combination thereof and (ii) a concentrated stream of CO2 through an indirect neutralization of ammonia with an acid selected from the group consisting of nitric acid, phosphoric acid, a salt thereof and a combination thereof;

• said method comprising:
• (a) reacting a carbon dioxide containing gas with a base capable of forming a carbonate product upon reaction with CO2, whereby a carbonate product is formed;
• (b) reacting a carbonate product containing a CO2 component from step (a) with a reagent selected from the group consisting of nitric acid, phosphoric acid, a salt thereof, and a mixture thereof to form CO2, and a fertilizer containing an ammonia component;
• and
• (c) separating at least a portion of said carbon dioxide from said fertilizer in a condensed and relatively concentrated stream.
