Trace Constituents in Landfill Gas. Task Report on Corrosion Potential. Final Report May 1984-June 1985

摘要

The report presents the results of a task performed for the Gas Research Institute (GRI) program entitled 'Evaluation of Gas Cleaning Technologies for Trace Constituent Removal'. The report summarizes work performed under Task I-1 of that program: 'Corrosion Potential of Trace Constituents in Landfill Gas'. Trace compounds present in landfill gas (LFG) were categorized into one of eight groups based on chemical characteristics. A method was then developed to identify those compounds which have a high probability of being present in cleaned product landfill gas. The corrosion potential for each group was evaluated qualitatively for its influence on pipeline materials and residential and industrial appliances, equipment, and facilities. Most gas treating plants for landfill gas remove the bulk of corrosive constituents before product LFG is added to the pipeline. Thus, the corrosion potential from cleaned gas is minimal.
