Development of a CO2 Capture and High-Purity Separation Process Using Aqueous Ammonia

「At its Kitakyushu Works, the company is developing a process that efficiently captures the CO2 emitted during coke production by converting aqueous ammonia into a fine mist, then separates the CO2 at high purity by reacting phosphoric acid with the aqueous ammonia containing the captured CO2. The process is characterised by its use of ammonia, a by-product of coke production, and by not requiring thermal energy for CO2 separation.」
