ABSTRACT:
Disclosed is a method and associated apparatus by which glycols may be cleaned, particularly those which have been used to dehydrate natural gas. Glycol contaminated with water, hydrocarbons, salts such as sodium chloride, and other impurities is degassed and physically separated from immiscible liquid hydrocarbons prior to passing through a quantity of absorbent material to remove the bulk of any residual hydrocarbons and filter particulates. The glycol is then routed through strong acid cation and strong base anion exchange resins to remove salts. The net product of the deionization is water which may easily be removed in a reboiler, yielding a clean, reusable glycol. Glycol which is not contaminated by petroleum impurity may be cleaned by strong acid cation and strong base anion exchange means alone.
