Physical Solvents in ProMax
Physical solvents are becoming increasingly popular as gas treating solvents, especially for coal gasification applications. ProMax accurately models a number of physical solvents such as DEPG (Coastal AGR), NMP or N-Methyl-2-Pyrrolidone (formerly Purisol), methanol (Rectisol), and others.

Physical solvents are becoming increasingly popular as gas treating solvents, especially for coal gasification applications. ProMax accurately models a number of physical solvents such as DEPG (Coastal AGR), NMP or N-Methyl-2-Pyrrolidone (formerly Purisol), methanol (Rectisol), and others. The physical solvents tend to be favored over ethanolamine 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.
