We offer a wide range of biogas safety and handling equipment. Biogas is produced during the biological breakdown of organic solids through anaerobic digestion. The gas generated through this process is an energy source which can be collected and utilized, or be safely burned. Biogas is a highly moist mixture of gases consisting of approximately 55-70% methane, 25-35% carbon dioxide and trace amounts of nitrogen and hydrogen sulfide. Biogas recovered may be used in a multitude of ways. Biogas can be used to run a boiler for heating the anaerobic digester or the plant. It can also be used to run an engine-generator to generate electricity.
Anaerobic digestion is one of the effective methods of treating biosolids from municipal and industrial wastewater. It is an ideal method in meeting strict environmental regulations in highly urban areas. The anaerobic process occurs in closed vessels (digesters), or covered ponds or lagoons. Soluble organics are converted to methane (CH4) and carbon dioxide (CO2) in a two-step process.
Biogas collection and utilisation is an important part of the anaerobic digestion process. The low heat content gas is saturated, and contains elements harmful to personnel. Biogas is also corrosive to piping and equipment. It is important to handle biogas properly to ensure a protected environment. The key aspect of design is to recognise that biogas handling equipment operates as a system.
