Calgren plant incorporates industry leading operational efficiencies and process conversion technology

Lurgi, Inc., a member of the Air Liquide group of companies based in Memphis, Tennessee, announces the successful completion and start-up of a state-of-the-art ethanol facility for Calgren Renewable Fuels, LLC (Calgren). Located in Pixley, California, the Calgren plant incorporates industry leading operational efficiencies and process conversion technology, and is the only ethanol plant currently operating in the state.

Calgren and Lurgi collaborated on unique designs that optimize the plant’s energy efficiency and incorporate the production of value added co-products.

The plant is powered by an Ultra Low NOX gas turbine generator capable of producing 5,800 kilowatts (KW) of electricity as well as process steam, which results in a 20 to 25 percent reduction of steam consumption compared to the industry norm. With one of the lowest carbon footprints of any ethanol plant in the United States, Calgren’s plant will have annual production of 55 million gallons of fuel alcohol and 400,000 tons of animal feed.

Ethanol is used as a transportation fuel or fuel additive and is typically manufactured by processing industrial waste streams or organic matter. The ability to capture and repurpose these feedstocks further enhances the value of ethanol as a cleaner burning alternative fuel that contributes to reducing greenhouse gas emissions and preserving our environment.

Chris Lloyd Jones, chairman of Lurgi, Inc. stated: “Lurgi is proud to have contributed technological expertise to Calgren’s success, and we congratulate them on their perseverance and on the achievement of this significant milestone. Lurgi is committed to helping pave the way for new energy and environment solutions, two growth drivers for the Group.”

Lyle Schlyer, president of Calgren Renewable Fuels, LLC commented: “We believe that our collaboration with Lurgi on this facility has resulted in one of the most energy efficient ethanol plants in the country.”

The successful implementation of Lurgi’s design modifications for the Calgren facility highlights its expertise as a world-leading technology and engineering company, and its exceptional capabilities to deliver innovative biofuels technology and value through customized solutions.
