DuPont confirms successful performance test
Published by Callum O'Reilly,
DuPont Clean Technologies has announced the successful performance test of a 3.4 million tpy 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 3Q18, with the system meeting all design requirements and product quality targets. Earlier in 2018, the refinery successfully started up a 2.6 million tpy IsoTherming vacuum gas oil (VGO) hydrogenation unit.
The 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 and downstream high pressure separation equipment, thus significantly reducing the capital cost for the unit. With the application of the recycle pump and the efficient use of the available heat from the reactor effluent, the unit operates with a significant reduction in operating costs as compared to conventional hydroprocessing technology.
With a total installed capacity of 440 000 bpd (Phase I and Phase II), the CNOOC refinery, whose Phase II project went into operation in September 2017, has already previously invested in technology from DuPont Clean Technologies. This latest development follows the installation of emissions lowering technology provided by the BELCO® wet scrubbing catalytic cracking flue gas desulfurisation technology, licensed by DuPont Clean Technologies, for two sets of fluid catalytic cracking flue gas dedusting units (FCCUs). The first is a 1.2 million tpy FCCU while the second has a capacity of 4.8 million tpy FCCU. The CNOOC Huizhou refinery also contains an alkylation unit utilising the STRATCO® alkylation technology, also under license from DuPont Clean Technologies, to convert low value isobutane and olefins into high value alkylate, a key ingredient for the production of clean gasoline.
Eli Ben-Shoshan, Global Business Leader, DuPont Clean Technologies, said: “We are delighted to support CNOOC with highly efficient and cost-effective technologies that allow the refinery to satisfy demand for cleaner transportation fuels in an economical way by reducing energy consumption and operating costs while meeting stringent quality and environmental standards.”
