Caustic Treating

Caustic treating is used on hydrocarbon streams to extract or sweeten mercaptans. One result of caustic treating is the formation of a very stable emulsion that cannot be separated effectively from the hydrocarbon with conventional equipment. The carried-over caustic leads to off-spec hydrocarbon products due to downstream haze or sodium levels.

Pentair Porous Media’s LiquiSep technology effectively separates even tight emulsions with low interfacial tension liquids, significantly reducing caustic carryover, and allowing hydrocarbon product streams to meet specification.
