Landfill Gas

There are more than 350 commercial landfill gas recovery operations in the U.S. alone which generate electricity on-site, supply industrial gas-fired boilers, or produce substitute natural gas fuels such as CNG. Historically, very few have required H2S treatment. However, many landfills are now accepting large quantities of construction and demolition (C&D) debris in addition to municipal solid waste (MSW), which can set in motion a number of factors that lower landfill gas quality and increase facility operations and maintenance costs. Gypsum wallboard in C&D debris generates hydrogen sulfide gas (H2S). In sufficient amounts, this will result in the need for sulfur abatement systems which can be expensive and complex.

Merichem’s LO CAT® process is highly effective in removing H2S from land fill gas. The first application of the LO CAT® technology specifically treating land fill gas was started up in the United States in 1995; and continues to treat gas to this day.
