MOSCOW (MRC) -- Chevron Lummus Global LLC (CLG) has announced the expansion of its technology portfolio with the addition of its new ISOTERRA process for renewable diesel and sustainable aviation fuel (SAF) from biomass sources, according to Hydrocarbonprocessing.
The two-step process involves hydrodeoxygenation of alternative feeds such as vegetable, algae, palm and used cooking oils. It is then followed by dewaxing to meet final cold flow property specifications.
ISOTERRA helps repurpose existing assets, making it ideal for revamping existing hydrotreaters to renewables service as the process can be implemented in either one or two reactor stages. The two-stage configuration allows feed and product flexibility and robustness, and the single-stage configuration provides a low CAPEX option for existing hydrotreating facilities.
“With today’s market drivers pointing towards a lower carbon future, operators need a technology that enables feed and product flexibility at low cost,” said Thad Sauvain, Global Licensing and Sales Director, Chevron Lummus Global. “Our ISOTERRA process provides those benefits to customers looking to process a wide variety of biomass sources or repurpose existing assets.”
As MRC wrote before, in July 2021, Lummus Technology and Chevron Lummus Global LLC (CLG) announced multiple technology contracts from North Huajin Refining and Petrochemical Co., Ltd. for a grassroots refinery and petrochemical complex in Liaoning Province, China. The complex will include one of the largest vacuum residue desulfurization (VRDS) units in China and one of the largest Novolen polypropylene (PP) plants. Lummus will provide the license and basic engineering for its Novolen PP technology, plus the associated catalysts. CLG will provide the license and basic engineering for the VRDS technology, plus proprietary reactor internals and catalysts.
We remind that, in April, 2021, Lummus Technology was awarded a master licensor contract by PJSC Nizhnekamskneftekhim for its ethylbenzene, styrene monomer (SM), ethylene dimerization and olefins conversion technologies. These four plants will be part of the expansion of an olefins production facility in Nizhnekamsk, Russia. The dimerization and olefins conversion units will be the first in Russia.
Ethylene and propylene are the main feedstocks for the production of polyethylene (PE) and polypropylene (PP), respectively.
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 1,638,370 tonnes in the first eight months of 2021, up by 10% year on year. Shipments of all grades of ethylene polymers increased. At the same time, PP shipments to the Russian market were 989,570 tonnes in the first eight months of 2021, up by 30% year on year. Deliveries of homopolymer PP and block-copolymers of propylene (PP block copolymers) increased, whereas shipments of injection moulding PP random copolymers decreased significantly.
