LO-CAT Treats Up To 15 MMSCFD Of Landfill Gas At Broward County, Florida

Source: Merichem Company -- Merichem Gas Technologies

The Broward County, Florida, landfill collects approximately 9 MMSCFD of landfill gas from 300 wells and converts the gas to electricity on-site at the nation's largest landfill gas turbine-to-energy plant.

Increasing H2S concentration in the landfill gas caused severe odor problems, corrosion in the compressors, and SO2 emission problems in the turbine exhaust gas.

A LO-CAT II hydrogen sulfide oxidation system was installed to treat up to 15 MMSCFD of landfill gas containing up to 5,000 ppmv H2S.

Since the start-up of the LO-CAT II systems, the SO2 emissions from the turbines at the Central Sanitary Landfill have been in compliance with permitted levels. Also, maintenance requirements associated with the high levels of H2S are a fraction of the costs prior to the installation of the LO-CAT II unit.
