US AD-derived biogas facility upgraded to produce renewable natural gas

High Plains Bioenergy (HPB), a subsidiary US-based Seaboard Foods, recently announced plans to upgrade its anaerobic digestion-derived biogas to renewable natural gas using a Carbotech pressure swing adsorption system from Wisconsin-based Bioferm Energy Systems/Viessmann Group.

Located in Guymon, Oklahoma, HPB’s facility 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.

Gene Binder, director of sales and business development at HPB, said: “One strategic element of our business model is an emphasis on identifying opportunities which result in economic as well as environmental benefits through the use of Seaboard Foods’ various waste streams.

“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.

Additionally, the selected Carbotech Pressure Swing Adsorption (PSA) technology provides the market’s lowest operating costs compared to other gas upgrading systems.
