Anaerobic digestion is the process by which organic matter such as animal or food waste is broken down to produce biogas and bio-fertilizer. This process happens in the absence of oxygen in a sealed, oxygen-free tank called an anaerobic digester. Biogas is primarily methane (CH4) and carbon dioxide (CO2) and hydrogen sulphide (H2S), moisture and siloxanes.

The gases methane, hydrogen, and carbon monoxide (CO) can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used for any heating purpose. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.

Anaerobic Digestion

Why monitor and analyze the gas I produce?

The composition of biogas is crucial. The most abundant component in biogas is methane, which typically makes up 50% to 60% of the gas. To verify the anaerobic conditions, biogas operators analyse gas for oxygen content, to ensure maximum levels of methane production to increase energy production. It is also necessary to monitor for levels of harmful gases that can damage the plant equipment such as hydrogen sulfide.

What benefits will I get?

Increased Return on Investment Protection of expensive plant equipment (CHP’s) Validation and optimization of the AD process

How do I do it?

Operators opt for fixed in line systems that will measure multiple sample points to ensure the process verification is monitored. These systems connect via industry standard protocols to the operators control systems housed on site. Portable analyzers offer flexibility for process monitoring at various points in the AD process to ensure maximum efficiency of the site.

How long does it take to produce biogas?

In a nutshell, biogas is a renewable form of energy that can be combusted to produce electricity, or directly to produce heat in the form of a flame. Let's take a look at how long it takes to produce.
