Patent number: 9359565Abstract: Systems and methods are provided for using field enhanced separations to produce multiple fractions from a petroleum input. A liquid thermal diffusion and/or electric field separation is used to produce the fractions. The fractions can then be used to form multiple outputs that share a first feature while being different with regard to a second feature. For example, a first fraction from the plurality of fractions can have a desired value for a first property such as viscosity index. Two or more additional fractions from the plurality of fractions can then be blended together to make a blended fraction or output. The blended fraction can have a value for the first property that is substantially similar to the value for the first fraction. However, for a second property, the first fraction and the blended fraction can have distinct values. As a result, multiple output fractions can be formed that share a first feature but differ in a second feature.Type: GrantFiled: December 18, 2013Date of Patent: June 7, 2016Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Krista Marie Prentice, Jason M. McMullan, Michel Daage, Gregory J. DeMartin, John Stephen Szobota, Ronald M.

Patent number: 5651877Abstract: A semicontinuous process for solvent dewaxing a waxy petroleum oil feed stream including the steps of: diluting of the waxy oil feed stream with solvent; feeding cold oil/solvent/wax mixture to a filter to remove the wax and obtain an oil/solvent filtrate stream; contacting the oil/solvent filtrate stream with a selective semipermeable membrane to selectively transfer solvent through the membrane to obtain a solvent-rich permeate; and periodically directing a warm stream of recovered solvent onto the membrane surface to wash the membrane and remove impurities therefrom.Type: GrantFiled: April 16, 1996Date of Patent: July 29, 1997Assignee: Mobil Oil CorporationInventors: Ronald M.

Patent number: 5494566Abstract: A process for solvent dewaxing petroleum feedstock to separate crystallized wax from lubricant oil by filtration of a wax/oil/solvent mixture. The feedstock is sequentially cooled and mixed with cold polar solvent to form a wax crystal phase and oil-solvent phase, and-the oil-solvent filtrate stream is contacted with solvent permeable selective membrane at low temperature to recover an internal circulating permeate solvent stream and an oil-rich retentate stream containing dewaxed oil product and residual solvent. Improved operation is achieved by splitting the internal circulating solvent stream into a multiple cold solvent recycle streams and injecting a plurality of the cold solvent recycle streams into the waxy petroleum feedstock during sequential cooling and mixing. By initially injecting a cold recycle solvent stream in to the waxy petroleum feedstock at a small temperature differential near the wax crystallization temperature, shock cooling and excess small wax crystal formation is avoided.Type: GrantFiled: May 26, 1994Date of Patent: February 27, 1996Assignee: Mobil Oil CorporationInventors: Ronald M. Gould, Albert R. Nitsch

Patent number: 5360530Abstract: A process for solvent dewaxing a waxy oil feed to obtain petroleum oil lubricating stock comprising the steps of contacting a warm waxy oil feed by indirect heat exchange first with cold filtrate, then with refrigerant to crystallize and precipitate the wax in the oil feed to form an oil/solvent/wax mixture. The oil/solvent/wax mixture is diluted with cold solvent to adjust the viscosity of the mixture and the mixture is fed to a filter which filters and removes the wax from the cold oil/solvent/wax mixture. A cold wax cake is recovered and a cold oil/solvent filtrate stream is recovered. The cold oil/solvent filtrate stream is fed, at the filtration temperature, to a selective permeable membrane. The membrane selectively separates the cold filtrate into a cold solvent permeate stream and a cold filtrate stream which contains the dewaxed oil and the remaining solvent. The cold solvent permeate stream at the filtration temperature is recycled to the filter feed stream.Type: GrantFiled: April 23, 1993Date of Patent: November 1, 1994Assignee: Mobil Oil CorporationInventors: Ronald M. Gould, William F. Heaney, Albert R. Nitsch, Howard E. Spencer

Patent number: 5358625Abstract: A process for solvent dewaxing a waxy oil feed to produce a lubricating oil by contacting a warm waxy oil feed in counter-current with a cold oil/solvent filtrate stream through a selectively permeable membrane to transfer cold solvent through the membrane to the feed and simultaneously cool the feed, dilute it with solvent and separate solvent from the cold oil/solvent filtrate stream. The cooled, diluted feed stream is then further cooled to precipitate the wax to form an oil/solvent/wax mixture which is further diluted with cold solvent and filtered to remove wax. The cold oil/solvent filtrate stream is cycled to the selectively permeable membrane for the counter-current contact with the warm waxy oil feed and, after removal of a portion of the solvent over the membrane, is sent to an oil/solvent separation operation in which the solvent is removed from the dewaxed oil.Type: GrantFiled: April 23, 1993Date of Patent: October 25, 1994Assignee: Mobile Oil CorporationInventor: Ronald M.

Patent number: 4689205Abstract: An apparatus for converting oxygenated feedstock, such as methanol, dimethyl ether or the like, to liquid hydrocarbons. In the primary catalyst stage the feedstock is contacted with a fluidized zeolite catalyst to produce C.sub.2 -C.sub.4 olefins and C.sub.5.sup.+ hydrocarbons.

Patent number: 4523046Abstract: Gasoline product yield is enhanced in a fixed bed methanol-to-gasoline process by splitting the conversion reactor into a series of smaller conversion reactors such that the total amount of catalyst normally present in the single conversion reactor is present in equal quantities in the smaller conversion reactors. The smaller conversion reactors operate sequentially with the next conversion reactor beginning operation only when the preceeding conversion reactor is catalytically exhausted. The by-passing of one or more of the catalyst beds prevents premature deactivation of the catalyst beds downstream of the point at which the reaction products are removed.Type: GrantFiled: February 25, 1982Date of Patent: June 11, 1985Assignee: Mobil Oil CorporationInventors: Ronald M.
