FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to recovery of blast-furnace and coke production gases. Method comprises separation of coke oven gas from coal carbonisation into hydrogen and residual flow gas containing hydrocarbons. Hydrogen separated from coke oven gas is added is added to synthesis gas flow rich in carbon monoxide produced from blast-furnace top smoke. Residual gas flow containing hydrocarbons is fed into blast-furnace process as a fuel.
EFFECT: lower costs.
