dc.description.abstract | Chemical absorption process for the reduction of $CO_2$ emission was investigated. Sterically hindered amine and ammonia aqueous solution have been suggested as alternative absorbents due to their promising advantages over conventional amine absorbent. Sterically hindered amine of 2-Amino-2-methyl-1-propanol (AMP) and ammonia aqueous solution were used as absorbents for $CO_2$ removal in this study. The fundamental design data for aqueous ammonia absorbent were investigated. Correlation and prediction of the solubility of $CO_2$ in aqueous ammonia solution at the arbitrary temperature and concentration were established using the Pitzer’s excess Gibbs energy. Reaction between $CO_2$ and aqueous ammonia solution were studied through the analysis of $CO_2$ contained ammonia absorbent by the solid-NMR, FT-IR and $^{13}C$ NMR measurement. FT-IR and $^{13}C$ NMR measurement revealed that $CO_2$ absorption reactions were influenced by the pH of solution. In the beginning stage of $CO_2$ absorption, $CO_2$ is absorbed through a very fast reaction of carbamate formation. Below the solution pH of 9.5, $CO_2$ is absorbed through a relatively slow reaction of bicarbonate formation. The maximum amount of carbamate occurred at about the $CO_2$ loading of 0.3 (or pH 9.5) for 5 - 25 wt% ammonia absorbent. Speciation through $^{13}C$ solid NMR revealed that the precipitates in aqueous ammonia solution of 5 - 25 wt% is ammonium bicarbonate and other solid product are not found in the experiment range. It is favorable to use the carbamate formation reaction in a chemical absorption process, and consequently, the optimum operating condition for $CO_2$ absorption process using aqueous ammonia absorbent is the rich- $CO_2$ loading of 0.3. The rate constant of $CO_2$ absorption reaction in aqueous ammonia solution was obtained using a stirred cell in the temperature range from 293 to 337 K. The rate constants were correlated in the form of Arrhenius equation, and the ac... | eng |
