FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. The method of producing ammonia involves compressing steam, hydrocarbon material and air. Before the air compression step, the air is cooled, while ensuring stoichiometric ratio of nitrogen and hydrogen in the process. The material is cleaned from sulphur compounds. Steam and steam-air conversion of methane and carbon oxide conversion steps then follow. The obtained nitrogen-hydrogen mixture is cleaned from oxygen-containing compounds, compressed and fed for ammonia synthesis in a closed cycle from which the ammonia product is separated in liquid form.
EFFECT: invention increases efficiency of the process and increases output of the end product.
