Catalytic dewaxing of lube oil production
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. The oils blended with additives to produce lubricants are the base oils. Hydroconversion (hydroprocessing and catalytic dewaxing) is applied in newer plants. 6 Jan 2018 Abstract: The use of zeolite catalysts for the refining of products from methanol synthesis and The gaseous hydrocarbons that are produced with crude oil production of lubricant base oils from vacuum gas oil cuts. based on MFI that are industrially used for catalytic dewaxing can be considered [55]. The optimization of the catalyst parameters to design good catalysts for the two processes is described. Keywords: Dewaxing; shape-selective cracking; wax isomerization; lube oil base stocks; fraction that is suitable for producing the. 2Senior Product Manager – Base Oils, Chevron Global Lubricants, 6001 Later processes like hydrotreating, catalytic hydrocracking, catalytic dewaxing, and Solvent-dewaxed Group III base oils have been produced in Europe for more.
Department Of Mechanical Engineering Production Services Department Abstract - Oil and gas industries in Nigeria mostly import base oils used in blending for the desired lubricants. Base oil is produced by means of refining crude oil. This means that the crude oil is heated in order that various distillates can be separated from one another.
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 Lubricating oil base stock is the principal product of interest. The main purpose of dewaxing is to remove hydrocarbons that solidify readily (i.e., wax) for making lubricating oil base stock with low pour points (-9 to 14°F). Figure 5.11. Feedstock for dewaxing and hydrocarbon composition of the feed and the products. Catalytic dewaxing is a high-temperature, high-pressure process in which a catalyst selectively cracks the wax molecules present in a base oil to light products, such as gas and naphtha. Although this process is efficient, it is somewhat wasteful, as high-value wax is converted to lower value gas and light fuel.

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.
