PROPOSAL NUMBER : 96-1 16.16-7970

PROJECT TITLE : Photo-Chemical Remediation (PCR) of Sites Contaminated with Hazardous Solvents

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

This proposal offers an innovative Photo-Chemical Remediation (PCR) technology for in-situ and environmentally safe destruction of chlorinated hydrocarbons (solvents) present in contaminated soils, groundwater and off-gas emissions. The proposed PCR is based on a synergistic effect achieved by combining photo-initiation with chain-propagation reactions in a reducing atmosphere and at moderate temperatures. The most innovative aspect of the PCR process is the employment of inexpensive ultraviolet light to photo-induce dechlorination in a reducing atmosphere. This enables the process to proceed at relatively low temperatures accomplishing fast and complete conversion to environmentally benign and valuable products without producing any undesirable by-products.

The overall objective of Phase I is to experimentally demonstrate the feasibility of the PCR process as a cost-effective, clean-up technology for hazardous wastes containing chlorocarbons. Phase I effort will focus on two model compounds (TCE and DCE). It will provide all the technical information needed for designing and constructing a pilot-scale (Phase II), which will serve as a demonstration unit for commercialization purposes (Phase III).

POTENTIAL COMMERCIAL APPLICATIONS
The major potential applications will be in hazardous waste clean-up operations. It will provide a cost-effective and environmentally safe technology for treatment of hazardous chlorocarbons present in soils, groundwater, and off-gas emissions. Further, it has the potential to turn environmental liabilities (chlorocarbons) into assets (light hydrocarbons).
