Clean Methane Systems incorporates a combination of four specific gas analyses.
- Siloxanes Analysis: This analysis measures the amount of several different types of siloxane, including hexamethyldisiloxane, octamethyltrisiloxane, and hexamethylcyclotrisiloxane, among others.
- Inorganic and Organic Sulfur Species: This test determines the levels of H2S, mercaptans, sulfides, disulfides, thiophenes, and other sulfur species present in digester gas.
- Volatile Organic Compounds and Non-Methane Organic Compounds: VOCs are measured by a specific analytical procedure that identifies and quantifies the concentrations of over 300 different organic compounds, including acetone, benzene, toluene, styrene, and carbon tetrachloride, among others.
- Major Gas Constituents: This test determines the presence and concentrations of the permanent gases contained in the digester gas sample. The major gases are methane, carbon dioxide, carbon monoxide, nitrogen, and oxygen. This analysis also includes the BTU value of the gas.
