Landfill Biogas Treatment Biogas Systems

According to the EPA’s most recent data (2007), the U.S. has over 1,700 active landfills.  Though the number of landfills has significantly decreased over the last 20 years, the average size of landfills has increased.  Landfill sites produce methane and carbon dioxide gases due to the natural decomposition of solid waste material.  Solid waste landfills are the second largest source of human-related methane emissions in the United States, accounting for approximately 23 percent of these emissions in 2007.

Historically, landfills have flared these methane gases, resulting in undesirable increased carbon emissions. Ever emerging environmental laws, at both the state and federal levels, now offer the landfill industry challenging requiremLandfill Biogas Treatmentents to collect and dispose of these gases.  In fact, these methane emissions from landfills represent a lost opportunity to capture and use a significant energy resource.  Instead of allowing landfill gas (LFG) to escape into the air, it can be captured, converted, and used as an energy source. Financial benefits and improved community relations now provide the landfill industry with multiple incentives to employ biogas conditioning
systems in the management of these gases.

Biogas conditioning systems are used in a variety of industries including waste water treatment facilities, dairies and landfills. Utilization of biogas conditioning systems provides landfills with an opportunity to collect and dispose of the high levels of methane found in landfill gases. Currently, many landfills are using untreated gas containing impurities such as; sulfur, chlorine, silicon and moisture, to generate power and fire boilers.  This untreated gas can make existing equipment such as boilers, engines, fuel cells and turbines more susceptible to increased damages, increased maintenance costs and shorter life spans.  Power generation equipment suppliers have specific inlet gas requirements. Western Biogas Systems provides landfills with gas conditioning systems which meet these requirements.

Biogas conditioning for power generation applications involves the removal of Siloxanes, H2S and moisture (dehydration).  Additionally, biogas conditioning for pipeline injection applications requires further purification involving CO2 removal.  This gas may then be converted to valuable pipeline gas, providing additional financial opportunities. 

Western Biogas Systems consults with landfill teams to explain the biogas conditioning concepts and designs a biogas conditioning system specific to each site’s needs.  The most cost effective system is engineered and then fabricated to those unique specifications.  Western Biogas Systems provides ongoing project consulting and directing.  Additionally, project start-up services, gas sampling, maintenance plans and performance guaranties are also available.

Let Western Biogas Systems be your partner in finding solutions for converting landfill gases to useable energy.   Together, we can produce a system which provides for the reduction of carbon emissions and equipment replacement costs associated with damage from untreated gases, as well as increased revenue earnings and positive community relations.
