The method for preparing high purity hydrogen by using carbon monoxide-containing by-product gas generated from steelwork and Water-Gas shift reaction system

摘要

The present invention relates to a process for removing impurities from a steelmaking process exhaust stream comprising carbon monoxide; Producing a stream comprising hydrogen and carbon dioxide using carbon monoxide in a water gas shift (WGS) reactor; Aqueous gas field using the heat generated in the reaction to produce steam in which the aqueous gas field will enter the reaction; Heating the steam in the boiler; And a post-treatment step of obtaining hydrogen, and a water gas reaction system therefor.
