METHOD FOR GENERATING SYNTHESIS GAS IN CONJUNCTION WITH A SMELTING PLANT Russian patent published in 2018 - IPC C21B5/06 C21C5/38 F27D17/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used in the production of synthesis gas in which a part of the smelting furnace gas, and/or a part of the converter gas, and/or a part of the coke furnace gas are mixed to produce two utility gas streams. First utility gas stream is produced from a mixture of at least two gas streams: smelting furnace gas, converter gas and coke furnace gas, second utility gas stream is produced from the converter gas, or smelting furnace gas, or from a mixture of the converter gas and smelting furnace gas, wherein the first synthesis gas stream comprising, as main components, CO and H₂ or N₂ and H₂, is produced from a first synthesis gas produced from the resultant first utility gas stream, and from the second flow form H₂ free gas comprising, as main component, CO is produced from the second stream.

EFFECT: invention allows developing a method for generating synthesis gas in conjunction with a smelting plant, with which it is possible to use raw gases in a metallurgical plant in different amounts and different composition as completely as possible in economic processes.
