氨法脱碳过程中氨逃逸规律及其抑制
Ammonia escape and its prevention in CO2 absorption process using ammonia solution
摘要
Abstract
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.关键词
