Document Type and Number:
WIPO Patent Application WO/2023/210874
Kind Code:
A1
Abstract:
A carbon dioxide capture, carbon resource utilization, and hydrogen production system for a steel mill of the present invention comprises: a reactor which is provided between a reduction furnace and a blast furnace to spray a basic alkali mixture solution from a reduction gas, a flue gas of the reduction furnace, to remove carbon dioxide and produce a reaction product, and then blows the carbon dioxide-removed flue gas into the blast furnace; and a hydrogen generator which generates hydrogen gas and oxygen gas, by using a carbon dioxide reaction product, from the reaction product generated from the reactor, and supplies the generated hydrogen gas as fuel to the blast furnace and supplies the generated oxygen gas to a melter-gasifier, wherein the reactor separates the carbon dioxide reaction product and a waste solution from the reaction product and stores the separated carbon dioxide reaction product for resource utilization thereof.
