Abstract: The invention relates to a method for removing mercury from mercury containing materials, such as feedstreams, natural gas streams, natural gas condensates, and so forth. The method involves passing a fluid (e.g., gas or liquid) stream containing mercury along a polymeric membrane contact module, while a cleaning or scrubbing solution passes along the other side of the membrane. The scrubbing solution facilitates removal of mercury from the first solution via, e.g., mercury reactive components contained in it.

Abstract: A method for recovering sulfur from an acid gas feed is provided. The method comprising the steps of mixing the acid gas feed and an absorption process outlet stream to form a combined Claus feed, introducing the combined Claus feed and a sulfur dioxide enriched air feed to a Claus process to produce a Claus outlet gas stream, introducing the Claus outlet gas stream to a thermal oxidizer, treating the thermal oxidizer outlet stream in a gas treatment unit to produce a dehydrated stream, introducing the dehydrated stream to a membrane sweeping unit to produce a sweep membrane residue stream and a sulfur dioxide enriched air feed, introducing a sweep air stream to a permeate side of the membrane sweeping unit, and introducing the sweep membrane residue stream to a sulfur dioxide absorption process to produce the absorption process outlet stream and a stack feed.

Abstract: A process for recovering a noncondensable gas from a gaseous mixture, the method comprising the steps of: supplying a gaseous mixture comprising a noncondensable component; supplying a sweep gas comprising a condensable component; introducing the gaseous mixture and the sweep gas to a swept membrane stage to obtain a retentate stream and a mixed permeate stream, the mixed permeate stream comprising at least a portion of the condensable component and at least a portion of the noncondensable component; introducing the mixed permeate stream to a vapor-liquid separator and subjecting the mixed permeate stream to thermodynamic conditions sufficient to condense most of the condensable component into a liquid, and obtain a raw noncondensable component stream, wherein the raw noncondensable component stream is enriched in the noncondensable component; and introducing the raw noncondensable component to a concentration unit to obtain a noncondensable component product stream enriched in the noncondensable component.
