Patent number: 11591529Abstract: In some examples, hydrocarbon feed and a diluent such as steam are mixed, and heated. A vapor phase product and a liquid phase product can be separated from the heated mixture. The liquid phase product can be hydroprocessed to produce a first hydroprocessed product. A pitch and one or more hydrocarbon products can be separated from the first hydroprocessed product. The pitch can be contacted with a diluent to produce a pitch-diluent mixture. The pitch-diluent mixture can be hydroprocessed to produce a second hydroprocessed product. A hydroprocessor heavy product and a utility fluid product can be separated from the second hydroprocessed product. The diluent can be or include at least a portion of the utility fluid product. The vapor phase product can be steam cracked to produce a steam cracker effluent. A tar product and a process gas that can include ethylene and propylene can be separated from the steam cracker effluent.Type: GrantFiled: November 4, 2019Date of Patent: February 28, 2023Assignee: ExxonMobil Chemical Patents Inc.Inventors: John R. DeLaney, John J. Monson, Teng Xu, Kendele S. Galvan

Patent number: 11473024Abstract: Systems and methods are provided for increasing the portion of a pyrolysis tar fraction that can be hydroprocessed by using a physical particle size reduction process on at least a portion of the pyrolysis tar fraction. The physical particle size reduction process can reduce the percentage of particles in the pyrolysis tar fraction that have a particle size of 75 ?m or greater, or 50 ?m or greater. It has been unexpectedly discovered that at least a portion of the particles having a size of 75 ?m or less, or 50 ?m or less, can be effectively hydroprocessed to form products of greater value while still reducing or minimizing the amount of fouling or plugging in a hydroprocessing catalyst bed. By increasing the number of particles having a size of 75 ?m or less, or 50 ?m or less, while selectively removing larger particles from the SCT fraction, a higher yield of hydrocarbon products can be achieved for a feed containing an SCT fraction.Type: GrantFiled: March 20, 2019Date of Patent: October 18, 2022Assignee: ExxonMobil Chemical Patents Inc.Inventors: John S. Coleman, Kendele S. Galvan, John J. Monson, Denise M. Burcham, Kapil Kandel

Publication number: 20220204866Abstract: Processes and apparatus for preparing a liquid hydrocarbon product are provided. In one embodiment, a process for prepreparing a liquid hydrocarbon product includes thermally-treating a tar to produce a first tar composition and blending the tar composition with a utility fluid to form a tar-fluid mixture. The process includes separating the tar-fluid mixture to form a first lower-density portion and a first higher-density portion containing solids. The process further includes thermally-treating the first higher-density portion to form a thermally-treated first higher-density portion to convert at least a portion of the solids to liquid.Type: ApplicationFiled: May 15, 2020Publication date: June 30, 2022Inventors: John J.

Patent number: 11352576Abstract: In some examples, a vapor phase product and a liquid phase product can be separated from a heated mixture that can include steam and a hydrocarbon. The liquid phase product can be catalytically cracked in the presence of a fluidized catalyst to produce a catalytically cracked effluent. A bottoms product can be separated from the catalytically cracked effluent. The bottoms product can be hydroprocessed to produce a hydroprocessed product. For example, the bottoms product can be hydroprocessed under pre-treater hydroprocessing conditions to produce a pre-treated bottoms product and the pre-treated bottoms product can be hydroprocessed under bottoms product hydroprocessing conditions to produce the hydroprocessed product. A hydroprocessor heavy product can be separated from the hydroprocessed product. The vapor phase product can be steam cracked to produce a steam cracker effluent. A tar product and an upgraded steam cracker effluent can be separated from the steam cracker effluent.Type: GrantFiled: November 4, 2019Date of Patent: June 7, 2022Assignee: ExxonMobil Chemical Patents Inc.Inventors: John R.

Patent number: 9890336Abstract: A method for removing sulfolane from hydrocarbon streams by serial separation using raffinate wash column and at least one raffinate wash drum. The separation may be particularly useful in retrofitting existing separation facilities to produce motor fuels meeting the specifications requiring lower sulfolane content. A method is provided for the purification of a hydrocarbon-containing stream having a sulfolane therein. The method includes separating a first sulfolane-depleted stream from a hydrocarbon stream in a first counter-current separation unit and then separating a second sulfolane-depleted stream from the first sulfolane-depleted stream in a second counter-current separation unit. The first and second counter-current separation units are preferably different and chosen from a raffinate wash column or at least one raffinate wash drum. An apparatus for performing the methods is also described.Type: GrantFiled: July 30, 2015Date of Patent: February 13, 2018Assignee: ExxonMobil Chemical Patents Inc.Inventors: John J.
