ABSTRACT:
BTEX and other hydracarbons are removed from oil field and refinery waste streams by countercurrent extraction techniques. The contaminated waste water is contacted with adsorbent particles, selected to adsorb BTEX and other hydrocarbons, circulating in counter current fashion to the waste water stream.
