Landfill Biogas Matrix Analysis

Biogas treatment system centek labsRenewable Energy

The age old saying of “One mans garbage…Is another’s mans Gold” is becoming true in the reclaiming of Biogas from landfill operations. While we still depend on fossil fuels as our primary energy resource, the use of newer and cheaper energy sources such as landfill gas are increasing throughout the world today.

Biogas, and particularly landfill gas, or LFG, is usually heavily contaminated with VOCs (Volatile Organic Contaminants). VOC levels can exceed 1,000 ppmv, and are usually at least 50 ppmv, requiring removal by specialized treatment equipment so LFG can be used as a reliable fuel. Treatment systems for heavily contaminated biogas utilize media that is regenerated on a continuous basis to prevent siloxanes, halogenated VOCs and other harmful VOCs from entering combustion equipment or being released to the atmosphere.

Silica Erosion. Centek Labs SyracuseOrganosilicons cause most of the damage to Internal Combustion (IC) engines, microturbines, boilers and SCR catalysts. We measure the organosilicon content, major gas components (methane, nitrogen, oxygen, carbon monoxide & carbon dioxide), complete VOC (volatile organic contaminant) spectrum, plus organic and inorganic sulfur of your biogas. From this analysis, our biogas molecular scientists can determine the fouling potential (from silica formation) and treatability of your biogas.

Additional services can be provided with your test results. We can develop a complete gas profile and determine the proper treatment processes needed to meet even the most stringent biogas specifications for use as a fuel. These treatment methods can include:

  • Siloxane (and other organosilicon) Removal
  • Moisture Removal
  • Sulfur Removal
  • Methane Content Upgrade
  • System Maintenance
