Solid Waste Landfill Gas-to-Energy, Florida

Application:

In order for the site to meet their air permit requirements for the new power generation plant, the H2S levels must be treated to below 140 ppm. The facility was looking for an economical solution with minimal operator attention.

MV Solution:

After an extensive vetting process the facility selected a six-vessel H2SPlus System to treat up to 4,500 SCFM as required to meet the permit level of 140 ppm H2S. The system is expandable as the LFG production increases.

And, we're pleased to share that our partners on this project were recognized by ACEC/MN for their engineering achievement. View article here,"HR Green project named ACEC/MN Grand Award Winner"

Metro Landfill Gas Processing Facility, Wisconsin

Application:

A solid waste disposal facility approached MV Technologies to provide a system that could treat 1,200 cfm of landfill gas being sent via pipeline to a Milwaukee wastewater treatment plant for use in turbines. H2S concentrations fluctuate anywhere from under 100 ppm up to 200 ppm. The pipeline requires a concentration of less than 100 ppm H2S.

MV Solution:

When the concentrations are detected to be above the pipeline requirement the LFG is treated through two 12’ diameter by 12’ tall fiberglass vessels containing a total of 2,016 ft3 of Iron Sponge media. With minimal treatment requirements this system has a bed life exceeding 800 days, providing an economical solution with minimal maintenance and attention.

Landfill Gas-to-Energy, Georgia

Application:

The renewable energy facility is designed, built, owned and operated by a regional energy service provider to collect the LFG, and use it as a fuel source to power generators. The facility is designed to generate 4.8MW, and requires treatment of a source H2S concentration of 1,700 ppm at 1,600 SCFM. The facility’s air emissions permit requires the H2S concentration to be below 200 ppm.

MV Solution:

To meet the H2S specification, MV supplied four 12’ diameter by 11’-8” tall vessels, with a total media capacity of 4,368 ft3 of media. Designed media bed life is 170-days. The treated LFG has an H2S concentration in the 0-10 ppm range. The facility bypasses a portion of the LFG and re-blends it with the treated LFG. The blended LFG is targeted to an H2S level to comply with the air permit. By operating the system in this manner, it cuts operating cost of the H2SPlus System by 12%.
