摘要
FIELD: chemistry.;SUBSTANCE: hydrocarbon raw material (5) and air (14) are fed to the conversion section (1) where the conditioned synthesis-gas (6) is received. The compressed conditioned synthesis-gas (6) is involved in reaction in the circuit (2) of high-pressure synthesis for obtaining ammonia. The flow (7) of rinse gas from the circuit (2) of the synthesis or the exhaust gas from the rinse gas recovery section, which comprises the inert impurities, is brought into contact with the nitrogen flow (10) produced in the process of air separation. The nitrogen flow (10) is in the liquid state or represents a mixture of liquid and gaseous nitrogen. The gas flow (8) is recycled to the synthesis circuit (2).;EFFECT: invention enables to increase the productivity of the plant and to improve the efficiency of ammonia production process.;12 cl, 4 dwg, 3 tbl, 3 ex
