HYDROGEN SUPPLY SYSTEM AND HYDROGEN SUPPLY METHOD Russian patent published in 2018 - IPC E21B43/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a hydrogen supply system and to a hydrogen supply method for producing hydrogen from hydrocarbons and supplying produced hydrogen. Hydrogen supply system includes: setting a reforming unit for steam-reforming hydrocarbons; a unit for carrying out converting carbon monoxide to carbon dioxide to produce a gas containing hydrogen and carbon dioxide from a reforming reaction of the water gas obtained from reforming unit setting; a first absorption unit for absorbing carbon dioxide contained in the gas obtained from the shift reaction unit, in the absorbing liquid; a hydrogenation unit for hydrogenating an aromatic compound by hydrogenation reaction of an aromatic compound with the gas which has passed through the first absorption unit; a regeneration unit for absorbing carbon dioxide from the absorbing liquid by circulating the absorbing liquid from the first absorber and subjecting the absorbing liquid to heating. Heat is released during the hydrogenation reaction.

EFFECT: invention provides reducing carbon dioxide emissions and increasing energy efficiency in the hydrogen supply system.
