Honeywell UOP technology powers largest US advanced biofuel plant

By UOP LLC | May 15, 2014

UOP LLC, a Honeywell company, announced May 15 that its trademarked UOP/Eni Ecofining process technology is powering the largest commercial advanced biofuel facility in the U.S., capable of producing more than 130 MMgy of renewable diesel.

The Diamond Green Diesel facility in Norco, La., converts inedible oils and other waste feedstocks to produce high-quality renewable diesel, also known as Honeywell Green Diesel. Renewable diesel produced using the UOP process is chemically identical to petroleum-based diesel and can be used as a drop-in replacement in vehicles with no modifications. Renewable diesel produced using the Ecofining process also features up to an 80 percent lifecycle reduction in greenhouse gas emissions compared with diesel from petroleum.

The facility, a joint venture of Darling International Inc. and Diamond Alternative Energy LLC, a subsidiary of Valero Energy, achieved all of its performance and quality targets.

“Commercial production at the Diamond Green Diesel facility is a significant milestone for the renewable energy industry,” said Veronica May, vice president and general manager for Honeywell's UOP renewable energy and chemicals business unit. “UOP has leveraged 100 years of refining technology to make real alternative fuels, including Honeywell Green Diesel and Honeywell Green Jet Fuel, from a range of inedible biofeedstocks.”

John Roach, senior vice president at Valero, said, “Both the performance of the Ecofining unit and the quality of the diesel produced has exceeded our expectations.”

Randall C. Stuewe, chairman and CEO at Darling, said, “The availability of sustainable feedstocks is a key driver for the continued growth of renewable fuels. One of the benefits of the Ecofining process is that the technology is capable of processing a variety of feedstocks collected and manufactured by Darling to produce high-quality Green Diesel.”

Fuel produced at the facility is designed to meet the U.S. EPA’s renewable fuel standard (RFS), which requires a minimum volume of transportation fuels sold in the U.S. to contain renewable fuel to help reduce greenhouse gas emissions. The Diamond Green Diesel facility will produce more than 200 million ethanol-equivalent-gallons per year of biomass-based diesel as defined under the RFS. 

UOP and Eni SpA jointly developed the Ecofining process, which uses hydroprocessing technology to convert inedible natural oils and animal fats to Honeywell Green Diesel. The fuel offers improved performance over petroleum-based diesel, including a high cetane value of 80 compared with a cetane range of 40 to 60 found in diesel at the pump today. Cetane value is the measure of the combustion quality of diesel. Higher cetane values help diesel engines operate more effectively. Diesel with high cetane can be blended with low-cetane diesel to help meet transportation requirements. Honeywell Green Diesel also offers high energy density and excellent performance at cold or warm temperatures.

In addition to Ecofining technology, the company has commercialized the UOP Renewable Jet Fuel Process, which was originally developed under a contract with the U.S. Defense Advanced Research Projects Agency to produce renewable jet fuel for the U.S. military. Honeywell Green Jet Fuel produced by this process technology can be blended seamlessly with petroleum-based fuel. When used in up to a 50 percent blend with petroleum-based jet fuel, Honeywell Green Jet Fuel requires no changes to aircraft technology and meets all critical specifications for flight.

UOP is also a partner with Ensyn Corp. in Envergent Technologies LLC, which offers RTP rapid thermal processing technology and equipment for the production of renewable heat, power and transportation fuels.

    Congrats! to UOP and Darling - so give us a view of the project economics - what is the projected capital cost of a 130-mgpy renewable diesel plant? What are the operating costs? What is the projected break-even sales price of the green diesel? can it compete with methyl esters, or will it be targeted to a higher value market? It was just a two or three years ago when the report was issued that the US Navy purchased ~ 500,000 gallons of renewable diesel for $8-million, or ~ $16 per gallon. How does the Green Diesel economics compare?
