The market for biomethane compressors is growing as livestock operations and landfills seek environmentally friendly solutions for handling waste pollutants such as methane gas and carbon dioxide. LeRoi biogas and biomethane compressors offer reliable and safe solutions for converting methane and carbon dioxide into electric power.
Livestock methane contributes to about ~14% of all greenhouse gas emissions. In the past, waste pollutants from livestock operations were pumped into large waste lagoons and eventually spread on farm fields as fertilizer. This caused nitrogen contamination to the soil and groundwater as well as the release of the greenhouse gas, methane. Today, many large livestock ponds are lined and covered, turning them into anaerobic lagoons or digesters. These lagoons/digesters produce a gas mixture of about 60 percent methane “natural gas” and 40 percent carbon dioxide.
LeRoi biogas and biomethane compressors safely collect and compress this low pressure gas mixture. The compressed gas is then sent through the separation process where it is converted into renewable energy while lowering greenhouse gas emissions. The compressed gas is separated into two streams. The product stream is about 96% methane, which is injected into local natural gas distribution systems to power homes and businesses. The waste stream includes the carbon dioxide and is sent to flare or a thermal oxidizer.
Landfills are also a large producer of greenhouse gasses, contributing to about 17% of all greenhouse gas emissions. Landfill gas is a mixture of methane and carbon dioxide and is a natural byproduct of decomposing organic materials. The mixture of gases is important to note because methane is 25 times more effective than carbon dioxide at trapping heat in the atmosphere, making it a more potent greenhouse gas than carbon dioxide.
Today, landfill waste collection begins as non-hazardous waste is collected in designated areas or cells. As these area fill, they are sealed off to allow decomposition, which causes the release of gases. Within these cells, the site will use horizontal trenches or a vertical well to collect gas. This gas is funneled to a biogas compressor which is the first step in converting landfill gas into electric energy.
