Biogas Treatment Systems

Biogas upgrade systems are used to remove undesired components in biogas, such as sulfur and moisture. These systems aim to enhance the quality of biogas, making it a more efficient and environmentally friendly energy source. Before providing information on biogas purification systems, let's first answer the question: What is biogas?

As the name suggests, biogas is a flammable gas mixture produced as a result of biological processes. By creating an anaerobic environment, a gas mixture known as biogas is generated from organic material. It contains 50-80% methane and 20-50% carbon dioxide. Biogas also contains minimal amounts of hydrogen, hydrogen sulfide, ammonia, and other gases in small quantities.

This process, commonly seen in nature, also occurs in places like swamps, seabeds, liquid manure storage pits, and the stomachs of ruminant animals. Organic material is converted into biogas by a variety of microorganisms. Additionally, a certain amount of energy (heat) and new biomass are produced.

Biogas is the waste product of these decomposing microorganisms. The composition of the gas, or the quality of the biogas, depends on the organic material being decomposed. The higher the methane and hydrogen content, the higher the calorific value and flammability of the biogas. Methane is a colorless and odorless gas with a boiling point of -162°C, and it burns with a blue flame. Methane is also the main component of natural gas. At normal temperature and pressure, methane has a density of approximately 0.72 kg/m³. Since carbon dioxide is slightly heavier, the density of biogas is slightly higher at 1.15 kg/m³.

Due to the accumulation of waste in animal farms, rice fields, and landfill sites, atmospheric methane concentration has increased by about 150% since the Industrial Revolution. As methane is a component of atmospheric chemical processes and a potent greenhouse gas, it contributes to the greenhouse effect. Increased methane emissions are making the Earth more vulnerable to harmful ultraviolet radiation from the sun. Although humans have been aware of biogas since the 17th century, the installation of biogas systems and facilities began in the mid-19th century.

With the industrial-scale production of biogas, the need to purify and remove gases and compounds that degrade the gas quality, cause corrosion, threaten human health, and harm the environment has arisen. Since 2015, Quatro Proses, with its specialized team in biogas processes, has been providing services to its clients in biogas purification, storage, dehumidification systems, biogas blowers, and biogas pressurization.
