High Plains Bioenergy Upgrading Biogas to RNG

The Oklahoma plant will now produce produce 440 million scf of renewable natural gas for grid injection at full capacity.

High Plains Bioenergy (HPB), a subsidiary of Seaboard Foods, plans to upgrade its anaerobic digestion-derived biogas to renewable natural gas using a Carbotech Pressure Swing Adsorption system from BIOFerm Energy Systems/Viessmann Group.

Located in Guymon, Okla., HPB currently fuels boilers with the biogas created from the anaerobic digestion of food processing pork waste, but has identified gas upgrading and natural gas grid injection as a better alternative biogas end-use to enable the highest possible return.

“One strategic element of our business model is an emphasis on identifying opportunities which result in economic as well as environmental benefits through the utilization of Seaboard Foods’ various waste streams,” Gene Binder, director of sales and business development at HPB, said in a statement. “After a long and comprehensive vetting process, we have decided to partner with BIOFerm on this project. Their commitment to cutting-edge technology and unmatched output gas specifications were among the many reasons for our decision.”

BIOFerm’s installation in Guymon will consist of a complete, integrated gas upgrading system—from biogas filtration, to biogas compression, through upgrading to natural gas pipeline quality requirements and treatment of off-gas—including a performance guarantee and comprehensive control system for the whole package.

The new BUP2000 gas upgrading system will annually produce 440 million scf of renewable natural gas (RNG) for grid injection at full capacity—equivalent to 3,371,544 gas gallon equivalent’s (GGE)/year and displacing the gasoline usage for approximately 6,743 cars.

“Seaboard Foods and High Plains Bioenergy showcase an unparalleled industry model for sustainability through their commitment to renewables,” Nadeem Afghan, president and CEO of BIOFerm Energy Systems, said in a statement. “We at BIOFerm Energy Systems are excited in working with such a professional team to help create the best value for their biogas in the form of clean RNG fuel by deploying a complete state-of the-art gas upgrading system.”

Once finished, HPB‘s Carbotech PSA upgrading system will have a raw biogas processing capacity of 1200 scf/minute and an expected product gas composition with almost 96 percent methane despite the high oxygen and nitrogen portion in the raw gas.
