Carbotech PSA gas upgrading, by BIOFerm, is a dry process operating with no water, wastewater or chemical products. Additionally, these systems are capable of:
– meeting stringent North American pipeline requirements;
– handling high-nitrogen gas;
– removing oxygen from the gas;
– removing volatile organic compounds (VOCs);
– recuperating most of the methane;
– not increasing methane losses over time.
BIOFerm offers complete, turnkey gas upgrading systems and gas-to-grid injection units as North America’s exclusive provider of Carbotech PSA (Pressure Swing Adsorption) plants through the Viessmann Group. Our gas upgrading plants utilize PSA technology to scrub raw biogas from AD systems, landfills, municipalities, wastewater treatment plants, agricultural operations, etc., to create a high-value RNG product .
Biogas can be combusted in a combined heat and power unit (CHP) to produce heat and electricity, or upgraded to renewable natural gas (RNG). RNG can then be used as clean vehicle fuel in the form of compressed natural gas and liquefied natural gas or injected into the natural gas pipeline.
Today, legislation, tax credits, and energy demands are all playing a critical role in the rise of economically viable RNG projects.
Over 900 of our Carbotech PSA systems have been installed to-date, including CNG and natural gas pipeline injection projects.
Unique in the biogas industry is our ability to provide modular, all-inclusive gas upgrading solutions that include all the necessary upgrading components:
Our pre-manufactured, pre-tested, and pre-assembled PSA systems upgrade biogas in an environmentally-conscious manner and typically result in a methane recovery rate of >99%. Onsite installation costs are often also minimized due to the skid-ready nature.
Carbotech PSA gas upgrading is a dry process operating with no water, wastewater or chemical products and includes the following steps:
Compared to typical chemical and water scrubber systems and membrane technology, the PSA technology has:
