Abstract
A system is disclosed for recovering and disposing of volatile organic contaminants, from water contaminated with organics, which system includes a pump to feed water from the body of contaminated water to the system, with indirect heat exchange and direct steam addition to raise the temperature of the water, a stripping vessel to strip the heated water with gas to strip the volatile contaminants from the water, gas supply to provide stripping gas to the vessel conduits to pass the removed volatile contaminants to a vessel containing a bed of adsorbent selective for the removal organics and regenerating the near-saturated bed by stripping with ambient air heated by heat exchange with the exhaust gas from a fuel-fired heater, passing the contaminant-containing regenerating gas from the regenerating bed to said fuel-fired heater, and combusting the contaminants in said fuel-fired heater.
