GAS CHEMICAL PRODUCTION OF HYDROGEN Russian patent published in 2020 - IPC C01B3/32 C01B3/52 C01B3/56 B01D53/62 

FIELD: gas industry.

SUBSTANCE: invention relates to gas-chemical production of hydrogen, which includes a unit for deep purification of raw material from impurities, a methane conversion unit, a unit for amine purification of gas from CO₂ and a unit for short-cycle adsorption (SCA), raw natural gas is supplied to a unit for deep purification of raw material from impurities. Purified natural gas after mixing with demineralised water and / or oxygen is fed into a methane conversion unit to obtain synthesis gas, synthesis gas from the methane conversion unit is fed directly into the amine gas cleaning unit from CO₂, after which the purified synthesis gas is fed into an additional membrane extraction unit CO: carbon monoxide in form of a retentate is withdrawn as a commercial product, and hydrogen-containing gas (HCG) in form of permeate is fed into SCA unit, from where purified gaseous hydrogen is supplied to additional hydrogen liquefaction unit. Carbon monoxide, gaseous and liquefied hydrogen from corresponding storage tanks is pumped to consumers as commercial products.

EFFECT: development of gas-chemical production, which provides high-purity hydrogen production on the basis of steam and / or oxidative conversion of methane, which generates output of a wide range of high-margin commodity products at gas chemical enterprises.
