Glycol dehydration flash separator

Solvent loss elsewhere] upstream units, for example for glycol dehydration glycol dumped with hydrocarbons separated in upstream flash drum/loss in downstream solvent stripper. 

Function is to strip species from the liquid to produce a quality bottoms product for example, a solvent ready to be recycled as in glycol dehydration, amine absorption, extractive distillation or water that has been stripped of contaminants as in Sour Water strippers deodorize edible oils. Used to regenerate solvent for absorption or extractive or azeotropic distillation. Other equipment that is used for stripping include distillation. Section 4.2, gas-liquid separators. Section 5.1 and gas-liquid-liquid separation in flash drum. Section 5.4. The general characteristics of gas-liquid contacting are described in Section 1.6.1. Other operations that use this type of contactor include gas absorption. Section 4.8 reactors. Sections 6.13-6.16 and 6.19 and direct contact heat exchange Sections 3.7-3.9. 

Feed concentration off specification [foaming in upstream absorber] /for glycol dehydration upstream flash separator passing water for oil or hydrocarbon in feed to SWS residence time for sour water in flash drum is < 20 min.
