Key Applications for Vacuum Pumps and Compressors in Renewable Natural Gas


·       Anaerobic Digestion: Liquid ring vacuum pumps assist in maintaining the required vacuum levels within anaerobic digesters. This facilitates the efficient breakdown of organic materials by microorganisms, promoting the production of biogas. While, liquid ring compressors are employed to compress the generated biogas, increasing its pressure for further processing or injection into the natural gas grid

·       Membrane Separation: Liquid ring vacuum pumps create the necessary vacuum conditions for the efficient operation of membrane separation systems, aiding in the separation of impurities from biogas. Compressors are utilized to increase the pressure of the purified biomethane before it is ready for injection into natural gas grids.

·       Pressure Swing Adsorption (PSA): Liquid ring vacuum pumps are instrumental in creating the required vacuum levels during the adsorption phase in PSA processes, facilitating the separation of gases. Liquid ring compressors play a role in compressing the extracted methane for further purification and upgrading.

·       Gas Boosting: Liquid ring compressors are crucial for boosting the pressure of biogas before it undergoes further processing or injection into natural gas grids. They ensure a consistent and reliable gas flow.

·       Amine Scrubbing: Liquid ring vacuum pumps aid in creating the necessary vacuum conditions for the amine scrubbing process, ensuring the removal of impurities such as CO2 and H2S from biogas. Liquid ring compressors contribute to increasing the pressure of the scrubbed biogas for downstream applications.
