Introduction
The primary feedstocks for ammonia production units are sweet gases (methane) and atmospheric nitrogen. Methane gas, after being mixed with steam and undergoing a reaction in the primary reformer, is converted into hydrogen, carbon monoxide (CO), and carbon dioxide (CO2). The reforming reaction is completed by injecting air into the secondary reformer,and simultaneously, the nitrogen required for the ammonia synthesis reaction is introduced into the process cycle via air. Carbon monoxide accompanying the process gas is converted to CO2 in subsequent stages, and the resulting mixture is directed to the CO2 absorption section for purification. CO2 is a byproduct of ammonia production units and, after separation, is sent as feedstock to urea units.
