ABSTRACT:
The invention is a system for removing volatile hydrocarbon contaminates from both water and moisture-ladened air. In detail the invention comprises a steam stripping system for mixing the contaminated water with steam, at below atmospheric pressure, providing clean water for reuse and contaminated steam and vaporized hydrocarbon contaminates. A first condenser receives the contaminated steam and vaporized hydrocarbon contaminates and condenses, at below atmospheric pressure, a portion of the vaporized contaminates and a portion of the contaminated steam into contaminate water. A second condenser thereafter further condenses the steam and hydrocarbon vapor. A gravity separator thereafter receives the contaminated water from the first and second condensers and the uncondensed steam and hydrocarbon contaminates from the second condensor and provides outputs comprising: separated contaminated water for recycling; condensed hydrocarbon contaminates for reprocessing; and passes the uncondensed hydrocarbon contaminates to activated charcoal absorbers. The contaminated moisture-ladened gas is passed through a third condenser which produces contaminated water which is recycled to the steam stripping system and the remaining uncondensed hydrocarbons are passed through the activated charcoal absorbers.
