The main function of biogas purification equipment is to treat and purify the generated biogas to meet specific usage requirements. The following are the main functions of biogas purification equipment:
Removing impurities: Biogas often contains impurities such as hydrogen sulfide, carbon dioxide, moisture, particulate matter, etc. These impurities can cause damage to the equipment and systems used in biogas, and also affect the quality of biogas. Biogas purification equipment can remove these impurities through different processes to improve the purity and stability of biogas.
Reducing sulfur content: Hydrogen sulfide in biogas is a toxic gas that can harm the environment and equipment, and can also have a toxic effect on catalysts in biogas utilization equipment (such as power generation units). Biogas purification equipment can effectively reduce the content of hydrogen sulfide in biogas through technical means such as absorption, oxidation, or desulfurization.
Carbon dioxide removal: The high content of carbon dioxide in biogas can affect its calorific value and combustibility, reducing the utilization efficiency of biogas. Biogas purification equipment can achieve the separation and removal of carbon dioxide through methods such as absorption, membrane separation, and compression, thereby improving the calorific value and utilization value of biogas.
Adjusting the composition of biogas: biogas purification equipment can adjust the content of methane, ethylene, nitrogen and other components in biogas according to different needs to meet specific usage requirements. For example, in the industrial field, high methane content biogas is needed to supply combustion equipment or power generation units.
In short, biogas purification equipment can effectively treat impurities in biogas, improve the purity and stability of biogas, and enable it to be better applied in fields such as thermal energy utilization, power generation, and automotive fuel, achieving efficient energy utilization and environmental friendliness.
