Abstract The invention is a system for removing volitile hydrocarbon contaminates from both water and moisture-ladened air. In detail the invention comprises a stripping system preferably 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.
A system for simultaneously removing hydrocarbon contaminates from water and moisture-ladened air comprising: stripping means for stripping the hydrocarbon contaminates from the contaminated water providing heated clean water and a first mixture of hydrocarbon contaminated steam and vaporized hydrocarbon contaminates; a first condenser means for receiving the first mixture and condensing a portion thereof providing a second mixture of contaminated water and condensed hydrocarbon contaminates and the remaining portion of the first mixture substantially comprising uncondensed hydrocarbon contaminates; separator means for receiving the contaminated water and condensed hydrocarbon contaminates from said first condenser means and the uncondensed hydrocarbon contaminates and providing separated condensed contaminated water, condensed hydrocarbon contaminates and uncondensed hydrocarbon contaminates; a second condenser means for receiving hydrocarbon contaminated moisture-ladened air providing contaminated water and uncondensed hydrocarbon contaminates; and absorber means for receiving the uncondensed hydrocarbon contaminates from said second condenser means and said separator means for absorbing same.
