Abstract
Nowadays acid gas removal from gas streams using physical solvents is very common. Till now eight processes that use seven different physical solvents has been developed. In this study economic-technical investigation of physical solvent processes, advantages, disadvantages and application of every process for capture of acid gas from a gas stream has examined. Also commercialized processes all over the world have investigated. It was found that physical solvents are appropriate for high pressure and concentrated acid gas streams and they use less energy and have higher degradation time compared to chemical solvents.
