CNOOC Huizhou Petrochemicals achieves China V diesel target
WILMINGTON, Del., – DuPont Clean Technologies announced the successful performance test of a 3.4 million tons/year IsoTherming® diesel hydrogenation (DHT) unit by CNOOC Huizhou Petrochemicals Co., Ltd. at its Huizhou refinery in Guangdong, China. CNOOC completed calibration of the IsoTherming® DHT unit at 100% load in the third quarter of 2018, with the system
“The DuPont IsoTherming® liquid phase hydrogenation technology is outstanding in terms of energy savings,” said Mr. Chen Chun, Chief Engineer of the CNOOC Refining and Marketing Division. “Huizhou's 3.4 million tons/year diesel liquid phase hydrogenation unit consumes only 4.33 kg of oil equivalent (EO) / t of raw materials, far lower than the traditional trickle bed unit energy consumption.”
The IsoTherming® technology uses the reactor effluent as a liquid recycle stream rather than a recycle gas system to deliver the hydrogen required for chemical reactions.
This advanced technology eliminates the need for a costly recycle gas compressor, high-pressure amine absorber
With a total installed capacity of 440,000
Mr. Eli Ben-Shoshan, Global Business Leader, DuPont Clean Technologies, commented, “We are delighted to support CNOOC with highly efficient and cost-effective technologies that allow the refinery to satisfy
The IsoTherming® technology is commercially proven to process a wide range of feedstocks, from kerosene to gas oils, including 100 percent light cycle oil. The units are designed to provide refiners with a constant saving on utilities in the magnitude of 30-60 percent compared to trickle bed technologies and the potential of 30 percent capital cost savings or more. To date, DuPont has 26 IsoTherming® hydroprocessing technology licenses globally. The IsoTherming® hydroprocessing technology is commercially proven in 16 operational units with capacities ranging from 1,500
