WebSelexol is a physical solvent, unlike amine-based acid gas removal solvents that rely on a chemical reaction with the acid gases. It is dimethyl ether of polyethylene glycol. Since no chemical reactions are involved, Selexol usually requires less energy than the amine-based processes. It has high selectivity for H2 S over CO 2 that equals to 9–10. WebThese solvents, and similar solvents being synthesized, are expected to be economically viable replacements for Selexol and Rectisol in pre-combustion capture of CO 2 without requiring the syngas to be cooled below ambient conditions. In addition, these solvents can be regenerated using waste or low-grade heat, which allows net electrical energy
