Steel Industries in Japan Achieve Most Efficient Energy Cutoff Chemical Absorption Process for Carbon Dioxide Capture from Blast Furnace Gas

摘要

The most efficient energy cut-off chemical absorption process has been developed in the project of COURSE50 (CO2 Ultimate Reduction in Steelmaking process by innovative technology for cool Earth 50). Through each long hours running by the use of several kinds of newly developed absorbents, high energy saving, utilization of far lower temperature, and extremely low influence of the process to steel making facilities downstream of the process have been tested and verified using of actual blast furnace gas in the steel works.
