DuPont’s integrated global services and technology delivery business, DuPont Sustainable Solutions, has successfully commenced its DuPont IsoTherming Diesel Hydrotreating Unit at the PetroChina Changqing Petrochemical Company refinery in Xianyang, China. The unit was previously licensed in 2011 to PetroChina. PetroChina Changqing Petrochemical Company is a unit of PetroChina Co. Ltd. (PTR - Free Report) .
Starting from DuPont’s process design work for the unit to its commissioning, the project took two years to complete. Unit commissioning works were completed from Jun 20-30, 2013. Within Jul 23-25, 2013, a successful performance test run at the design throughput, with the design basis feed, was conducted maintaining the diesel product specifications.
The unit is specially designed to produce low sulphur diesel, which is complaint with the local diesel sulphur specifications of less than 50 wppm (weight parts per million), when processing 0.6 MMTPA (million metric ton per annum) (12,487 BPSD) of a 67% Light Cycle Oil (LCO) / 33% Straight Run Diesel (SRD) blend.
PetroChina produces high-quality, low-sulphur diesel, which is compliant with local environmental regulations on using DuPont’s advanced IsoTherming Hydroprocessing Technology. The uniqueness of this technology is that it reduces energy consumption and operating cost, provides higher reliability and increased operating flexibility, with higher product quality when compared with conventional hydroprocessing.
The technology uses novel reactor system to remove sulphur and other contaminants from petroleum liquids and motor fuels; whereas other typical hydroprocessing techniques use hydrogen in contact with a solid catalyst for the same. The usage of a novel reactor system makes it superior hydroprocessing technologies. DuPont Sustainable Solutions’ Clean Technologies licensed and markets IsoTherming Hydroprocessing Technology from its Leawood, KS, office.
DuPont Sustainable Solutions is one among its 12 business groups. It offers consulting services, products and technologies that help organizations protect people and the environment, use assets more efficiently, and improve worker skills and performance.
