DuPont announced that Allied Energy has selected DuPont IsoTherming hydroprocessing technology for its ultra-low diesel (ULSD) project at its Transmix Processing Facility in Birmingham, AL.
Development began in July 2015, with project startup anticipated by August.
IsoTherming hydroprocessing technology is licensed and marketed by DuPont as part of its Clean Technologies portfolio in Overland Park, KS.
Today, DuPont has 25 IsoTherming licenses globally, with 11 of that number in commercial operation.
IsoTherming technology is used for kerosene hydrotreating, transmix hydrotreating, diesel hydrotreating, FCC feed hydrotreating, mild hydrocracking, dewaxing, gas-to-liquid (GTL) upgrading and heavy oil.
Licensed IsoTherming unit capacities range from 1,500 barrels per day up to 80,000 barrels per day processing feedstocks such as 100 percent kerosene, 100 percent light cycle oil (LCO) and various mixtures of distillates and heavy gas oils..
Refiners are looking for ways to increase production. At the same time, more stringent environmental regulations and the processing of less expensive sour and heavy feedstocks make meeting this demand even more challenging, a DuPont release stated.
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 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, the DuPont release stated.
The 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.
