DEFINITION Gas absorption is a unit operation in which soluble components of a gas mixture are dissolved in a liquid usually called the lean solvent or simply lean oil. oil is regenerated in a desorption or stripping process and recycled to the absorber as l

42、ean oil in a continuous operation. The efficiency of the absorber is affected by the completeness of the rich oil regeneration. Normally the rich solvent or rich In gas processing, “absorber“ usually connotes the tower in which the gas stream is contacted with lean oil to remove a por- tion of the h

Strictly speaking, the “contactor“ used to remove CO2 or H2S in gas treat- ing is an absorber, as is the “contactor“ used in dehydration with a glycol solution. The testing of these “absorbers“ is similar to the testing of the lean oil absorber. Note: It is a
