What is Physical Solvents for Acid Gas Removal about?

The document compares several physical solvents for removing acid gases like CO2 and H2S from gas streams: DEPG (Selexol), methanol (Rectisol), and NMP. It discusses the operating conditions and applications of each solvent, noting their advantages like non-corrosiveness, but also disadvantages like high capital costs for methanol due to its low operating temperatures requiring refrigeration. Physical solvents are generally favored over chemical solvents for high acid gas concentrations and when treating sy
