제목 CO2 absorption characteristics in aqueous potassium carbonate with 2-methylpiperazine and piperazine
초록 Absorption by chemical absorbents is a suitable method for CO2 capture from large quantities in the flue gas. Aqueous K2CO3 solution has high CO2 solubility and low heat of absorption as good as amine solution, while its absorption rate is very slow. Amines as absorption rate promoters have been blended with aqueous K2CO3 solution in order to improve the performance of CO2 absorption rate. In this study, piperazine (PZ) and 2-methylpiperazine (2-MPZ), cyclic diamines were used as a rate promoter. The CO2 absorption capacity and heat of absorption were measured by using vapor-liquid equilibrium (VLE) apparatus and a differential reaction calorimeter (DRC), respectively. Aqueous K2CO3/PZ solution and K2CO3/2-MPZ solution had 50% higher CO2 absorption capacity and 23% lower heat of absorption than aqueous monoethanolamine (MEA) solution.
