Abstract

In this research, absorbents for CO2 capture were prepared by blending 30 wt% potassium carbonate, 3 wt% of a rate promoter, and 1 wt% of a corrosion inhibitor. Pipecolic acid, sarcosine, and diethanolamine were chosen as rate promoter candidates. Based on a rate promoter screening test for CO2 loading capacity and absorption rate, pipecolic acid and sarcosine were selected to be used as rate promoters. 1,2,3-benzotriazole and ammonium thiocyanate were chosen as corrosion inhibitors, and they were mixed with a 30 wt% potassium carbonate-based absorbent mixture containing one of the rate promoters. The absorption rates for four absorbent solutions (30 wt% potassium carbonate + 3 wt% pipecolic acid + 1 wt% 1,2,3-benzotriazole, 30 wt% potassium carbonate + 3 wt% pipecolic acid + 1 wt% ammonium thiocyanate, 30 wt% potassium carbonate + 3 wt% sarcosine + 1 wt% 1,2,3-benzotriazole, and 30 wt% potassium carbonate + 3 wt% sarcosine + 1 wt% ammonium thiocyanate) were measured, tabulated, and graphically displayed. These types of absorbents can be used for capturing CO2 under high temperature and pressure conditions, such as those found in coal-fired power plants.
