Title:
METHOD AND APPARATUS FOR COLLECTING CARBON DIOXIDE AND RECOVERING HYDROGEN FROM STEELMAKING BYPRODUCT GAS
Document Type and Number:
WIPO Patent Application WO/2017/111503
Kind Code:
A1
Abstract:
The present invention provides a method for collecting carbon dioxide and recovering hydrogen from steelmaking byproduct gas. A method and apparatus for collecting carbon dioxide and recovering hydrogen from steelmaking byproduct gas according to the present invention have the advantages in that by using a hollow fiber separating membrane and an absorbent the process is simpler than the prior art technology, the apparatus can be made smaller, and the apparatus has low installation and operating costs, etc. In addition, even in the case of gas which has not undergone a water-gas shift (WGS) reaction and contains moisture and other impurities, carbon dioxide can be stably separated and hydrogen can be recovered, thus providing the advantages in that the burden of pretreatment is low and energy efficiency is high.
