FIELD: oil and gas industry.
SUBSTANCE: invention relates to petrochemical industry. Natural gas 21 is fed into compressor 11. Compressed natural gas 21 is successively heated in fourth 20 and first 12 heat exchangers. In first heat exchanger 12 heat source used is flue gases 22. Heated natural gas 21 is fed into desulphuration device 13. In apparatus 14 there is reforming of natural gas purified from sulphur-containing compounds, and H2 and CO or H2 and CO2 are obtained. Gas subjected to reforming is used for synthesis of ammonia, urea and methanol. In second heat exchanger 16 air 26 used for heating in reforming apparatus 14 is heated. Water 75 is heated by flue gases 22 in third heat exchanger 19.
EFFECT: invention improves thermal efficiency during reforming of natural gas, prevents corrosion, improves efficiency of producing ammonia, urea and methanol.
