제목 Effects of adding an organic acid to reduce energy requirement for MEA solvent recovery of the stripping process in the CO2 capture system
초록 Chemical absorption is the most popular technology in CO2 capture system. This technology is more mature than other CO2 capture technologies and proper for large scale plants. MEA(Mono-ethanolamine) has been used as an absorbent to capture CO2 because it has high reactivity and low solvent cost. However, CO2 absorption process using MEA has disadvantages and one of those is that the regeneration energy of MEA solvent is higher than those of other amine based solvents in the general stripping process.

This work focuses on effects of adding an aqueous organic acid, such as benzoic acid, to decrease MEA recovery energy in the stripper. The acid can reduce CO2 solubility in aqueous MEA solution and the energy to separate MEA and CO2 would be lower. To confirm effects of adding the acid in the stripping process, CO2 solubility in aqueous MEA solution and in a mixture of aqueous MEA and benzoic acid solutions were measured at different weight percent ratio of MEA and the benzoic acid. Through the solubility data, effects of adding the acid in the stripping process could be estimated.
