MOSCOW (MRC) -- DuPont Clean Technologies (DuPont) has announced that an IsoTherming hydrotreating unit installed at the CNOOC Huizhou Refinery in Guangdong Province, China has successfully completed its performance test, certifying that the unit is meeting performance guarantees, according to Hydrocarbonprocessing.
The IsoTherming® VGO hydrotreater at CNOOC is designed to process 51,419 bpsd (2,600 kmta) of a vacuum gasoil feedstock as feed for the FCC unit. The IsoTherming® hydrotreater was designed for output of <1000 wppm sulfur and <600 wppm nitrogen.
The VGO hydrotreater was initially commissioned in late September 2017 but, due to the market-driven, reduced refinery throughput, the IsoTherming VGO hydrotreater ran at various lower rates until recently. The performance test results highlight the IsoTherming technology’s ability to sustain catalyst activity over a long period of time with the unit still satisfying performance guarantees.
CNOOC has indicated the IsoTherming VGO hydrotreater had a lower investment cost and offered greater than USD4,000,000 per year savings in utility costs compared to conventional trickle bed technology. This, along with sustained catalyst performance, has provided CNOOC both an economic and social benefit.
Operating costs savings in the form of reduced consumption of utilities, as well as capital cost advantages when compared to conventional technologies were key drivers for CNOOC to select the IsoTherming® technology for this project. CNOOC also chose the IsoTherming® technology for a 71,637 bpsd (3,400 kmta) ULSD hydrotreating unit (again at the Huizhou refinery) which was also commissioned in September 2017 after passing its performance test in 2018.
It’s great to see how the IsoTherming technology showcased sustained catalyst performance over the past few years with the unit still able to achieve start-of-run performance guarantees,” said Kevin Bockwinkel, global business manager, IsoTherming® hydroprocessing technology.
IsoTherming® hydroprocessing technology utilizes a novel liquid phase reactor system that is superior to conventional hydroprocessing technologies, as it uses the hydrogen and catalyst more efficiently. It also offers lower capital and operating costs compared to conventional hydroprocessing technologies in achieving the desired product quality. This technology is suitable for a wide range of applications, including kerosene hydrotreating, transmix hydrotreating, diesel hydrotreating, FCC feed hydrotreating (VGO hydrotreating), mild hydrocracking, dewaxing, gas-to-liquid (GTL) upgrading, and heavy oil upgrading for both grassroots and revamp configurations.
To date, DuPont has 27 IsoTherming® hydroprocessing technology licenses globally, of which 15 are in commercial operation. These licensed units include a diverse set of applications ranging from 100 percent kerosene to 100 percent light-cycle oil (LCO), and various mixtures of distillates and heavy gas oils, including coker blends, with capacities ranging from 1,500 bpsd to 80,000 bpsd.
Growing global demand for cleaner transportation fuel continues to drive refiners toward operations that maximize hydroprocessing capacity and capability through unit debottlenecks or new unit construction. More stringent environmental regulations and the processing of cost-advantaged sour and heavy feed stocks make meeting this demand even more challenging. Licensed and marketed by DuPont, as part of its Clean Technologies portfolio in Overland Park, Kansas, USA, IsoTherming® hydroprocessing technology provides a proven solution to meet this growing global demand.
As MRC informed earlier, China's top offshore producer CNOOC Ltd reported record-high oil and gas output of 257.9 million barrels of oil equivalent, or 1.42 million boe/d, in the first half of 2020, despite the COVID-19 pandemic dampening global energy demand.
We remind that CNOOC will trim annual investment by 10% to 15% in 2020, while maintaining its goal of increasing domestic crude oil and natural gas production for the year, according to the company's statement in May, 2020.
We also remind that in early May, 2018, China National Offshore Oil Corporation (CNOOC) and Shell Nanhai B.V. (Shell) announced the official start-up of the second ethylene cracker at their Nanhai petrochemicals complex in Huizhou, Guangdong Province, China.
Ethylene and propylene are feedstocks for producing polyethylene (PE) and polypropylene (PP).
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 1,496,500 tonnes in the first eight months of 2020, up by 5% year on year. Shipments of all ethylene polymers increased, except for linear low desnity polyethylene (LLDPE). At the same time, PP shipments to the Russian market reached 767,2900 tonnes in the eight months of 2020 (calculated using the formula - production minus exports plus imports - and not counting producers' inventories as of 1 January, 2020). Supply increased exclusively of PP random copolymer.
