  • Patent number: 4529413
    Abstract: A mixture of a dessicant-antifreeze, water and significant amounts of hydrogen sulfide is fractionated to produce a first vapor phase predominating in dessicant-antifreeze and hydrogen sulfide and a first liquid phase of essentially purified water and the first vapor phase is contacted with a stripping gas, inert with respect to the dessicant-antifreeze, to produce a second gas phase predominating in stripping gas and the hydrogen sulfide and a liquid phase of essentially purified dessicant-antifreeze. The first gas phase is preferably cooled and separated into the third liquid phase predominating in dessicant-antifreeze and a third vapor phase containing the remainder of the hydrogen sulfide and the third liquid phase is utilized as the feed to the stripping step. In the latter embodiment the second and third gas phases are combined and utilized as previously indicated.
