The present invention entails a method and an apparatus for removing BTX-type gases from a liquid. Herein is disclosed a system where purified water from an oil-water separator is directed into a vacuum chamber. The chamber is closed and a vacuum is pulled on the purified water causing BTX-type gases associated with the water to vaporize and assume a space in the upper portion of the vacuum chamber. The pressure within the vacuum chamber is continuously sensed as well as the liquid level within the chamber. Once the pressure within the vacuum chamber has reached a predetermined level and the level of the purified water is within a certain range within the vacuum chamber, then the BTX-type gases are removed via a vacuum pump and these BTX gases are collected in a collector where they are condensed to form a liquid.
