Patent number: 9498738Abstract: Systems and methods are provided for performing field enhanced separations on a feed, such as a petroleum feed, a refinery feed, or another type of hydrocarbonaceous feed. The system can allow for increased throughput of feed per volume of the separation device or system while performing a desired amount of field enhanced separation. The field enhanced separation can include separation by thermal diffusion, optionally enhanced by the presence of an electric field in the channel for performing the separation by thermal diffusion.Type: GrantFiled: July 18, 2014Date of Patent: November 22, 2016Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Amar S. Wanni, Lei Zhang, Jason M. McMullan, Gregory J. DeMartin, Michel Daage

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. Gould, Anastasios Ioannis Skoulidas, Ajit Bhaskar Dandekar, Patrick Loring Hanks, Charles Lambert Baker, Jr., Lei Zhang, X B Cox, III

Patent number: 8529663Abstract: The present invention relates the separation of a target gas from a mixture of gases through the use of engineered structured adsorbent contactors in pressure swing adsorption and thermal swing adsorption processes. Preferably, the contactors contain engineered and substantially parallel flow channels wherein 20 volume percent or less of the open pore volume of the contactor, excluding the flow channels, is in the mesopore and macropore range.Type: GrantFiled: April 4, 2008Date of Patent: September 10, 2013Assignee: ExxonMobil Research and Engineering CompanyInventors: Sebastian C. Reyes, Harry W. Deckman, Ronald R. Chance, Gregory J. DeMartin, Frank Hershkowitz, Eugene R. Thomas, Paul S. Northrop, Bruce T. Kelley, Edward W. Corcoran, Jr.

Patent number: 6733572Abstract: The present invention is a process for separating propylene and dimethylether from a mixture comprising propylene, dimethylether, and propane. The mixture is passed through a bed of an adsorbent comprising a porous crystalline material having (i) diffusion time constants for dimethylether and propylene of at least 0.1 sec−1, and (ii) a diffusion time constant for propane of than 0.02 of the diffusion time constants for dimethylether and propylene. The bed preferentially adsorbs propylene and dimethylether from the mixture. The adsorbed propylene and dimethylether are then desorbed from the bed.Type: GrantFiled: July 30, 2002Date of Patent: May 11, 2004Assignee: ExxonMobil Chemical Patents Inc.Inventors: Sebastian C.
