Abstract
Abstract The invention provides a method of generating solvent used in the separation of gases from mixtures of gases at high pressure by selective physical absorption in which a jet pump is used to obtain subatmospheric pressure in the final stage of pressure reduction. In comparison with known methods, the invention offers reduced power requirements, simplicity of construction and increased reliability of operation.

Claim 1

134 words
A method for the regeneration of a solvent used in a physical absorption process for the removal of selected components of a gas mixture at superatmospheric pressure, which method comprises the steps of:- (a) releasing absorbed gas or gases from the solvent in one or more flash stages at a superatmospheric pressure below that used in the absorption stage or any preceding flash stage; (b) releasing further absorbed gas or gases from the solvent in a flash stage at or near atmospheric pressure; (c) using the gas or gases released at superatmospheric pressure, wholly or in part, as the motive fluid to drive one or more jet pumps to develop a subatmospheric pressure in one or more flash stages in which regeneration of the solvent by release of absorbed gas or gases is completed.
