In this study, the new solubility data at high pressure condition applicable to pre-combustion $CO_2$ capture system were found. Experiments were conducted within the temperature range of $40{\sim}80^{\circ}C$ while increasing the pressure from 0 to 50 bar. The effect of MDEA (N-methyldiethanolamine) concentration was studied by varying the concentration from 30 to 50 wt%. In order to improve the absorption rate of MDEA, piperazine was added in ranging of 5~10 wt% into the MDEA solution as a activator. From this experiment, the equilibrium partial pressure was increased with increasing MDEA concentration in absorbent and reaction temperature. Also absorption rate was increased with increasing the reaction temperature. It was noted that the mixture of piperazine and MDEA aqueous solution showed faster absorption rate by 2.5 times than only the MDEA aqueous solution with 40 wt% cencentration at initial reaction stage and also increased absorption capacity by 16%.
