TREATING WASTE FROM GLYCOL DEHYDRATOR USING PERVAPORATION

摘要

Pervaporation processes and apparatus with few moving parts. Ideally, only one pump (4) is used to provide essentially all of the motive power and driving force needed to operate pervaporation unit (9) and move the various fluids into and out of separator (6) and across the feed side of the pervaporation unit. The process is particularly useful for handling small streams with flow rates less than about 2,652 L/day (700 gpd). Specifically, the process can be used to treat waste streams from glycol dehydrator regeneration units.
