As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. The production of biogas is an anaerobic process in which micro-organisms break down (digest) biodegradable material in the absence of oxygen. This biogas is then processed and used as fuel for cogeneration engines or sold to the national energy grid.
To monetize biogas and create the most efficient fuel sources, it is critical to accurately measure how much biogas is produced in each stage of the process. Accurately measuring biogas is an inherently challenging application with its changing gas composition, low pressure, and dirty, wet gas. Finding an accurate mass flow meter measurement solution for this challenging application increases a facility’s efficiency and revenue stream due to increased biogas and energy production.
