Gas-Phase Chemical Reduction Process for Site Remediation

Gas-Phase Chemical Reduction Process for Site Remediation 

A gas-phase chemical reduction process has been developed for site remediation. This section summarizes the findings of the US Environmental Protection Agency (US EPA) regarding the Gas-Phase Chemical Reduction Process developed by ELI Eco Logic International, Inc. (ECO LOGIC) of Ontario, Canada (47). 

Under the auspices of the SITE Program, and in cooperation with the City of Bay City, Michigan Environment Canada and the Ontario Ministry of the Environment and Energy US EPA conducted the demonstration of the gas-phase chemical reduction process at Bay City s Middleground Landfill. The landfill accepted municipal and industrial wastes for approx 40 yr. A 1991 remedial investigation indicated elevated 

A scmbber (46,47) treats the reformed gas to remove hydrogen chloride and particulates. Of this gas, 95% recycles back into the reactor and 5% feeds a propane-fired boiler prior to release to the atmosphere. The recycle stream may be used as a fuel in other system support equipment, such as the boiler that generates steam. The final combustion step in the boiler met the RCRA requirements, making the reformed gas environmentally acceptable for combustion. 

The US ERA collected extensive samples at points around the major system components and stored or logged important data on system operation and utility usage. Laboratory
