A method and apparatus for desulfurizing a gas and regenerating a sorbent is disclosed. The sulfur-containing feed gas which can be an effluent gas from a coal gasification reactor, for example, is desulfurized with a particulated metallic oxide sorbent in a transport riser. The sulfided sorbent is ...

Cribb Graham Thame Stanley: Process for separating gases. Gas Council, June 27, 1962: GB899611-A (25 worldwide citation)

Carbon dioxide is separated from gas mixtures by passing a stream of the gas through an absorbtion tower or column wherein the carbon dioxide is absorbed by a 2N to 8N ammoniacal solution lean in CO2, to produce a solution rich in CO2, passing the resulting solution through a heat exchanger under a ...
