物理溶剂如DEPG（SelexolTM或Coastal AGR）、NMP或N-甲基-2-吡咯烷酮（Purisol）、甲醇（Rectisol）和碳酸丙烯酯（Fluor SolventTM）作为气体处理溶剂越来越受欢迎，特别是在煤气化应用中。当酸性气体或其他杂质的浓度非常高时，物理溶剂往往优于化学溶剂。此外，物理溶剂通常可以通过降低压力而无需加热来汽提杂质。本文比较了四种物理溶剂DEPG、甲醇、NMP和碳酸丙烯酯的酸性气体去除能力、所需设备和功率要求。
Physical solvents such as DEPG (SelexolTM or Coastal AGR), NMP or N-Methyl-2Pyrrolidone (Purisol), Methanol (Rectisol), and Propylene Carbonate (Fluor SolventTM) are becoming increasingly popular as gas treating solvents, especially for coal gasification applications. Physical solvents tend to be favored over chemical solvents when the concentration of acid gases or other impurities is very high. In addition, physical solvents can usually be stripped of impurities by reducing the pressure without the addition of heat. This paper compares the acid gas removal ability, required equipment, and power requirements for the four physical solvents DEPG, Methanol, NMP, and Propylene Carbonate.
