ABSTRACT:
A system and method is disclosed for removing dissolved organic impurities, such as gasoline or other hydrocarbons, from groundwater. The contaminated water is fed into a stripper column, operated under a deep vacuum, to enable the water to enter the column at its boiling point. Steam, as a vaporizing gas, strips the impurities out of the water and the overhead vapor phase is compressed to boost it to a higher pressure, so it can be condensed to vaporize part of the bottoms stream from the column. Since the bottoms stream is mostly water, the vapor generated is the steam used to strip impurities from the water.
