Landfill Gas (LFG) Utilization
LFG Cleanup Technology
FirmGreen
patented and proprietary landfill gas (LFG) cleanup technology can process
LFG into renewable fuels such as compressed
natural gas (CNG), methanol or hydrogen, depending on local market
needs. Methane produced from FirmGreen technology is two to three times
cleaner than required by fuel cells which can convert the hydrogen-rich
gas into electricity without using combustion.
One of our standard 1000scfm landfill gas plants can produce enough clean burning alternative fuels to power more than 1500 cars per year, assuming an average annual fuel consumption of 714 gallons. Fuel production figure is based on 330 days fuel production per annum, with downtime expected for routine scheduled maintenance. The fuel consumption figure above is based on an average annual mileage of 15,000 and average fuel economy of 21 miles/gallon.
The figures above and below assume that the biogas is processed for direct use as vehicle fuel rather than for electrical generation.
One 1000scfm facility can be expected to provide an annual environmental benefit to the host community equivalent to any one of the following:
- Removing emissions equivalent to 21,680 vehicles
- Carbon sequestered annually by 26,900 acres of forest
- Removing emissions from 275,256 barrels of oil consumed
- Removing emissions from 13 million gallons of gasoline consumed*
* Data based on EPA studies and emissions factors
FirmGreen is a licensee of the patented CO2 Wash® to convert landfill gas (LFG) into clean energy such as renewable electricity and alternative fuels for vehicles.
Landfill gas is a natural product of the biological decomposition of organic waste. The resulting gas has a variety of chemical components, but at most municipal landfills the two principal components are methane (CH4) and CO2, with much smaller amounts of hydrogen sulfides (H2S), inerts and volatile organic compounds (VOCs).
A major problem with LFG projects is the presence of trace components. Typical LFG contains heavy hydrocarbons (both aliphatic and aromatics such as benzene) as well as numerous chlorinated hydrocarbons. These trace compounds are in some cases toxic or hazardous and also cause rapid failure or engine and turbine components.
The CO2 Wash® process removes contaminants from LFG using liquid carbon dioxide obtained directly from the LFG, and produces a stream of contaminant-free methane and CO2.
