METHOD AND DEVICE FOR PERFORMANCE OF MEMBRANE GAS/LIQUID ABSORPTION AT ELEVATED PRESSURE Russian patent published in 2002 - IPC

FIELD: methods and devices for performance of membrane gas/liquid absorption at elevated pressure. SUBSTANCE: device has excessive pressure vessel accommodating membrane unit for separation of continuous flow of gas phase and liquid phase in such a sequence as to provide for change of components subject to absorption between gas phase and liquid phase. In this case, direction of gas phase passage through absorber, in essence, is perpendicular to direction of liquid phase flow through absorber. Invention also relates to method of conduction of membrane gas/liquid absorption in which given absorber, particularly, for absorption of CO₂, H₂S, mercury (vapor) and/or water (steam) from gas phase at elevated pressure. Invention also deals with method of cleaning of natural gas with use of absorber and method in compliance with invention. EFFECT: absorption of various components from gas phase. 3 dwg
