1-866-4-BIOGAS Staff/Clients Login About Us Products Field Services Custom Fabrication ... Home / Products Products PRODUCTS Biogas is produced during the biological breakdown of organic solids through anaerobic digestion. The gas generated through this process is an energy source that can be collected and utilized, or safely burned. Biogas is a highly moist mixture of gases consisting of approximately 55-70% methane (CH₄), 25-35% carbon dioxide (CO2) with trace amounts of nitrogen and hydrogen sulfide. When recovered, biogas may be used in a multitude of ways such as; running a boiler for heating an anaerobic digester or used to run an engine-generator to generate electricity. Anaerobic digestion is one of the most 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), covered ponds or lagoons. Soluble organics are converted to CH4 and CO2 in a two-step process. Biogas collection and utilization is an important part of the anaerobic digestion process. The low-heat-content gas is saturated and contains harmful elements that are also corrosive to piping and equipment. It is important to handle biogas properly to ensure a safe and protected environment. The key aspect of design is to recognize that biogas handling equipment operates as a system, making Varec Biogas the leading experts and your total solutions provider.
