چکیده
• CO 2 chemical absorption with aqueous NH 3 is experimentally and theoretically investigated. The process dynamics simulated for the first time by a deterministic mathematical model. model capable to successfully predict ion speciation capture efficiency evolution. validated predicting experimental output under different operating conditions. possibility use optimize columns operation/regeneration cycle discussed. It well known that re-use one of main challenges be pursued in order tackle global warming issues. Aqueous ammonia solutions are among most promising sorbents post-combustion could represent valid potentially economical alternative conventional alkanolamines, due their higher capacity, lower energy requirements sorbent regeneration greater resistance oxidative thermal degradation. Despite its apparent simplicity convenience, dynamic evolution ? system needs further investigated through proper models permit design, optimize, control process. In this work, carbon dioxide contained flue gas ( N + ; 15 % v / ) means was both theoretically. particular, rigorous model, quantify composition during process, proposed time. comparing modeling results data obtained effect temperature concentration good agreement between confirms effectiveness reliability developed tool turns out able variation Therefore, it may exploited properly absorbent section whose also depend on species into solution.
