With awareness of environmental protection in recent years
control of greenhouse gas emission has become an important issue. A large port of CO2 come from power plants combustion of fossil fuel
and its capture is necessary for fire-coal power plants. Chemical absorption of CO2 by alkaline absorbent is one of widely use methods. Among the removal technologies of air pollutants by chemical absorbents
ammonia method has many advantages. However
ammonia method has a serious ammonia escape problem
leading to a less favorable selection for the application. The effects of CO2 concentration
ammonia concentration
absorption temperature on ammonia escape were experimentally investigated in the paper. Based on consideration of coordination chemistry principle
some metal ions were selected and studied as additives. The results indicated that addition of Ni2+ showed a good performance for the control of ammonia escape
and it was confirmed by the results obtained by UV-visible spectrophotometer. These results could be valuable for solution of ammonia escape.
