BIOGAS PRODUCTION FROM ANAEROBIC DIGESTION
|The anaerobic digestion process is based on the decomposition of organic matter in waste into a suitable digester, under specific conditions of temperature, pH and substrate, with the presence of a combination of bacteria and the absence of oxygen, to produce gas mixture-called biogas and digested residue (digestate slurry).|
Specifically, the biological process of decomposition with Anaerobic Digestion involves the following steps:
- Acetogenesis and
Biogas is widely used to produce electricity.
For the development of small-scale facilities, biogas, after removal of volatile bodies, sulfur compounds and moisture, is used as fuel in piston engines that propel power generators of electrical power 0,5 - 3,3 MW.
Biogas can be used as heating fuel for industrial boilers, furnaces, ovens, and dryers. After removing moisture, biogas is suitable for various applications such as:
- space heating,
- production of thermal energy, fuel for boilers producing steam heating,
- electricity generation using steam turbines
