CO₂Absorption Characteristics of Physical Solvent at High Pressure

Abstract

>> In this study, as a candidate of the carbon dioxide (CO2) absorbents, the mixture solution of polyethylene glycol dimethyl ether (PEGDME) and tetrahydrofuran (THF) were investigated. CO2 absorption rate was measured by using high pressure CO2 screening equipment in the range of 1-10wt% THF. Absorption capacity of the mixture solution was also estimated. Based on the results, we found that mixture solution containing THF had higher absorption rate and CO2 loading capacity compared to PEGDME at 25℃.
