文摘

Metal ions M(II) = Zn(II), Cu(II) and Ni(II) were investigated as ammonia loss inhibitor. Directly reduction of ammonia concentration was introduced to suppress ammonia loss. Both methods suppress ammonia loss at a cost of CO2 absorption rate. Both methods decrease CO2 absorption capacity and increase solvent regeneration energy.
