چکیده انگلیسی
CO2 solution loading were evaluated. The parametric impacts are similar to those of traditional amine-based absorption processes. Although the reactivity of aqueous ammonia is moderately lower than MEA, the KGav value of aqueous ammonia is the same order of magnitude as that of MEA under the same operating conditions. As the liquid flow rate increases aqueous ammonia can achieve a performance comparable to MEA solvent. Long-term stability tests showed the absorption performance of aqueous ammonia remained constant in the first hour and then gradually decreased over time. Precipitation of ammonium salts was observed on the membrane surface of the shell side, which caused membrane fouling and may facilitate membrane wetting.
