The Crude Unit was built in 1985 and has a capacity of 11,000 barrels per stream day. between catalyst regeneration and a catalytic hydrodesulfurization unit was added to the production of naphtha solvents and minimize the the production of gasoline. The Methyl Ethyl Ketone (MEK) Dewaxing Unit was built in 1969.
Although included under the separation processes, catalytic dewaxing is actually good product stability;; flexibility to produce both lube oil base stock and light

Catalytic dewaxing is used in base oil production to isomerise straight-chain paraffins to reduce cold flow properties while maximising yield. To get the best base oil manufacturing results, refiners need expertise across the entire value chain. Shell Catalysts & Technologies is uniquely positioned to design, deploy, and support these solutions. 7.3.9 Catalytic Dewaxing. Catalytic dewaxing is a particular hydrocracking process used to improve cold flow properties of middle distillates and lubricants by cracking normal paraffins. Dewaxing can be achieved by isomerization, as carried out by Chevron's isodewaxing process. Isoparaffins have lower melting points than normal paraffins. In several lube-refinery applications, Mobil Oil Corp. has demonstrated process improvements in the areas of vacuum distillation, solvent refining, lube hydrocracking, and catalytic dewaxing. This Lubricant base stock dewaxing (MSDW™ technology) Read how MSDW™ selective dewaxing technology allows refiners to improve base stock cold-flow properties and convert wax to high viscosity index lubricant. Learn more These properties can be calibrated and improved through a process called catalytic dewaxing. Business value Topsoe’s dewaxing technology radically reduces the yield loss of the diesel fraction by as much as 30% compared to conventional dewaxing technologies. Chevron was the first to combine catalytic dewaxing with hydrocracking and hydrofinishing in its Richmond, Calif. base oil plant in 1984 4 (Figure 1). Figure 1. ChevronTexaco’s Richmond, Calif. Lube Oil Plant (RLOP) This was the first commercial demonstration of an all-hydroprocessing route for lube base oil manufacturing.
Catalytic dewaxing using commercial Criterion catalysts is our most recent technology application and lies at the heart of lubricants production in the world’s largest GTL plant, the shell Pearl GTL facility in Ras Laffan, Qatar. Lubricant base stock dewaxing (MSDW™ technology) Read how MSDW™ selective dewaxing technology allows refiners to improve base stock cold-flow properties and convert wax to high viscosity index lubricant. A process for making a lubricant oil of low pour point which comprises a) catalytically dewaxing a lube boiling range feedstock in the presence of hydrogen over a dewaxing catalyst comprising an The results showed that the additon of metallic components enhances the activity of catalyst, produces the low pour point diesel oil, and greatly reduces the pour point of lube base oil. The catalyst impregnated with Fe was more effective than one impregnated with Co. The qualities of oil production were also improved more with H-ZEM-5 than ZEM-5. Dewaxing of lubricating oil base stocks is necessary to ensure that the oil will have the proper viscosity at lower than ambient temperatures. Two types of process are used; selective hydrocracking and solvent dewaxing. In the formar, one or two zeolite catalysts are used to selectively crack the wax paraffins. The latter is more prevalent. These cracking-type catalysts have been widely used for stand-alone dewaxing of distillates as well as lube oils [,, ]. Attempts to achieve similar performance with other zeolites such as MOR [ 4 ] were not overly successful, mainly due to lack of selectivity, i.e. excessive gas make and hence less favorable economics. Two new lubricant base oil plants are using state-of-the-art hydrodewaxing technology to produce clean, high-quality base stocks (Fig. 1 shown above). The hydroprocessed base stocks are
