Abstract
A method has been discovered for recovering hydrocarbon contaminants from wastewater. The wastewater is contacted countercurrently with stripping gas. The stripping gas is passed over a bed of activated carbon to remove hydrocarbon contaminants. Periodically, the activated carbon bed is regenerated with steam. Steam condensate and hydrocarbon contaminants are passed to a petroleum desalter. Hydrocarbon contaminants are transferred to the petroleum.
