New Clean Fuel Unit to Provide Ultra-Low Sulfur Diesel at Lower Cost

DuPont is pleased to announce that Allied Energy has selected DuPont™ IsoTherming® hydroprocessing technology for its ultra-low diesel (ULSD) project at its Transmix Processing Facility in Birmingham, Alabama. Development of the technology package began in July 2015, with project startup anticipated by August 2016.

IsoTherming® hydroprocessing technology is licensed and marketed by DuPont as part of its Clean Technologies portfolio in Overland Park, Kansas. Today, DuPont has 25 IsoTherming® licenses globally, with 11 of those in commercial operation. IsoTherming® technology is suitable for a wide range of applications, including kerosene hydrotreating, transmix hydrotreating, diesel hydrotreating, FCC feed hydrotreating, mild hydrocracking, dewaxing, gas-to-liquid (GTL) upgrading and heavy oil upgrading for both grassroots and revamp configurations. Licensed IsoTherming® unit capacities range from 1,500 bpd up to 80,000 bpd processing feedstocks such as 100 percent kerosene, 100 percent light cycle oil (LCO) and various mixtures of distillates and heavy gas oils, including coker blends.

Growing global demand for transportation fuel continues to drive refiners toward operations that maximize hydroprocessing capacity and capability either through unit debottlenecks or new unit construction. More stringent environmental regulations and the processing of cost-advantaged sour and heavy feedstocks make meeting this demand even more challenging. Typical hydroprocessing techniques use hydrogen in contact with a solid catalyst to remove sulfur and other contaminants from petroleum liquids. IsoTherming® hydroprocessing technology employs a novel reactor system that is superior to conventional hydroprocessing technologies by using the hydrogen and catalyst more efficiently. IsoTherming® technology offers the refiner lower capital and operating costs while significantly reducing sulfur content in motor fuels.

DuPont’s Clean Technologies division applies real-world experience, history of innovation, problem-solving success, and strong brands to help organizations operate safely and with the highest level of performance, reliability, energy efficiency and environmental integrity. Our Clean Technologies portfolio includes STRATCO® alkylation technology for production of clean, high-octane gasoline; IsoTherming® hydroprocessing technology for desulfurization of motor fuels; MECS® sulfuric acid production and regeneration technologies; BELCO® air quality control systems for FCC flue gas scrubbing and other refinery scrubbing applications; MECS® DynaWave® technology for sulfur recovery and tail gas treating solutions; and a comprehensive suite of aftermarket service and solutions offerings.
