Coury, G E

A noncondensable gas such as H/sub 2/S is removed from a condensable vapor in a two-sided heat exchanger employing multi-stage condensation or counter current flow, and the condensate so formed is employed as a cooling medium on the opposite side of the heat exchanger while itself being vaporized into a clean gas. In multi-stage condensation, a portion of the condensate is formed at each stage of a system and the condensate so formed does not progress to the next stage. In a counter current flow system, the condensate is at least temporarily retained in the condensing area so that additional noncondensable gas may be stripped from the condensate by the gaseous mixture of noncondensable gas and condensable vapor. Before condensate from either type of system is employed as a coolant, it is subjected to flash evaporation.
