High Plains Bioenergy to upgrade biogas with Bioferm system

By Bioferm Energy Systems | October 04, 2016

High Plains Bioenergy, a subsidiary of Seaboard Foods, recently announced plans to upgrade its biogas to renewable natural gas (RNG) using a Carbotech Pressure Swing Adsorption system from BIOFerm Energy Systems, part of Viessmann Group. Located in Guymon, Oklahoma, HPB currently fuels boilers with the biogas created from the anaerobic digestion (AD) 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,” said Gene Binder, director of sales and business development at HPB. “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. HPB’s dedication to clean energy, fuel and waste management alternatives from and for Seaboard Foods’ operations helps promote sustainable food systems and communities. Aiding these efforts, its new BUP2000 gas upgrading system will annually produce 440 million standard cubic feet (scf) of RNG for grid injection at full capacity—equivalent to around 3.4 million gas gallon equivalents per 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,” said Nadeem Afghan, president and CEO of BIOFer Energy Systems. “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 1,200 scf per minute and an expected product gas composition with almost 96 percent methane despite the high oxygen and nitrogen portion in the raw gas.

A high-value RNG product paired with minimal operating costs and reduced installation costs from the system’s pre-tested modular design enables HPB to reach the highest return over the project’s lifetime.

Carbotech PSA systems provided by BIOFerm Energy Systems, Viessmann Group come pre-manufactured, pre-tested and pre-assembled in North America and upgrade biogas in an environmentally conscious manner. It can result in a methane recovery rate of around 99 percent.

Key features of Carbotech PSA gas upgrading include: turnkey system offerings with all necessary upgrading components; the capability of meeting stringent pipeline requirements; removes oxygen from the gas; removes nitrogen from the gas; uses no chemicals and minimal process water for desulphurization; capable of handling high-nitrogen gas; in-house volatile organic compound removal technology; high methane yield and no increased methane losses over time; low operating costs and system efficiency; modular approach; and technology emphasis on high processing efficiency.
