ECO LOGIC INTERNATIONAL GAS-PHASE CHEMICAL REDUCTION PROCESS - THE REACTOR SYSTEM - APPLICATIONS ANALYSIS REPORT
Sudell, G. ECO LOGIC INTERNATIONAL GAS-PHASE CHEMICAL REDUCTION PROCESS - THE REACTOR SYSTEM - APPLICATIONS ANALYSIS REPORT. EPA/540/AR-93/522, 1994.
The ELI Eco Logic International Inc. (Eco Logic) process thermally separates organics, then chemically reduces them in a hydrogen atmosphere, converting them to a reformed gas that consists of light hydrocarbons and water. A scrubber treats the reformed gas to remove hydrogen chloride and particulates. A portion of the gas is recycled back into the reactor; the remainder is either compressed for storage or feeds a propane-fired boiler prior to release to the atmosphere. The Gas-Phase Chemical Reduction process is designed to treat aqueous and oily waste streams and soil and sludge contaminated with hazardous organic waste, such as PCB, PAHs, chlorinated dioxins and dibenzofurans, chlorinated solvents, chlorobenzenes, and chlorophenols. The Eco Logic process was demonstrated at the Middleground Landfill in Bay City, Michigan under a Toxic Substances Control Act research and development permit during October and November 1992. The test was performed using PCB-contaminated wastewater, waste oil and soil from the site. Test results yielded a 99.99 percent destruction and removal efficiency for PCBs during all runs, a 99.99 percent destruction efficiency for a tracer compound (e.g., perchloroethylene) and a net destruction of trace feedstock dioxin and furan compounds during all runs. Treatment costs based upon demonstration data fell between $6-7/gal of liquid treated.
