Method for treating vapors and liquids recovered from a subsurface remediation process

Abstract

A continuous process for removing organic contaminants from a subsurface formation. Including the steps of (a) injecting steam into the subsurface formation via an injection conduit, (b) removing a liquid stream from the subsurface formation via a liquid recovery conduit, (c) removing a vapor stream from the subsurface formation via a vapor recovery conduit, the vapor stream comprising both condensible vapors and non-condensible vapors, (d) combining the liquid stream and the vapor stream to create a combined stream and cooling the combined stream in a heat exchanger so that substantially all of the condensible vapors are condensed to condensed liquids, the condensed liquids being combined with the ground water liquid stream to form a combined liquid stream, and (e) separating the non-condensible vapors from the combined liquid stream.
