Publication number: 20160185688Abstract: Hydrocarbon processing apparatuses and processes for producing n-pentane and isobutane are provided herein. In an embodiment, a process for producing n-pentane and isobutane includes providing a hydrocarbon feed stream that includes C4 and C5 hydrocarbons. A recycle stream that includes C4+ hydrocarbons and the hydrocarbon feed stream is combined to produce a combined feed stream. The combined feed stream is separated to produce an iC4 product stream, an nC5+ product stream, and an iC5/nC4 feed stream. The iC5/nC4 feed stream is simultaneously disproportionated and isomerized in an isomerization zone to produce an intermediate stream that includes C3-C6 hydrocarbons. The C3-C6 hydrocarbons in the intermediate stream are separated to produce a C3? stream and the recycle stream that includes C4+ hydrocarbons.Type: ApplicationFiled: December 30, 2014Publication date: June 30, 2016Inventors: Mark Paul Lapinski, David Lowry, Matthew Lippmann, David James Shecterle

Publication number: 20160175760Abstract: Process for adsorbing a species from a feed gas stream. Feed gas stream is introduced to an adsorption zone having a sorbent. Species from the feed gas stream is adsorbed onto the sorbent at an adsorbing temperature to enrich the sorbent with the species and deplete the species from the feed gas stream. Species-lean product gas stream is output. Species-rich sorbent from the adsorption zone is passed to a regeneration zone. Regenerant gas at a regenerating temperature greater than the adsorbing temperature is introduced into the regeneration zone to strip the species from the species-rich sorbent. Regenerated sorbent from the regeneration zone passes to a cooling zone disposed below the regeneration zone. Regenerated sorbent is cooled at a cooling temperature below the regenerating temperature. Cooled sorbent is transferred to the adsorbent zone.Type: ApplicationFiled: December 18, 2014Publication date: June 23, 2016Inventors: Clayton C. Sadler, David A. Wegerer, Matthew Lippmann

Patent number: 9302956Abstract: A process for increasing a yield of an isomerization zone by removing at least a portion of the C6 cyclic hydrocarbons from a stream prior to it being passed into the isomerization zone. Additionally, disproportionation reactions occur producing valuable C3 hydrocarbons and C4 hydrocarbons. Also, a higher ring opening conversion of C5 cyclic hydrocarbons is observed.Type: GrantFiled: May 1, 2014Date of Patent: April 5, 2016Assignee: UOP LLCInventors: Mark P. Lapinski, Matthew Lippmann, Gregory Funk, David James Shecterle, Lakshmi P. Mokka

Patent number: 9302960Abstract: A process for producing a feed for a stream cracker. At least a portion of the C6 cyclic hydrocarbons are removed from a stream prior to it being passed into an isomerization zone. Disproportionation reaction selectivity is increased, producing valuable C3 hydrocarbons and C4 hydrocarbons. Also, a higher ring opening conversion of C5 cyclic hydrocarbons is observed. The yield may be adjusted by controlling an amount of C6 cyclic hydrocarbons passed to the isomerization zone. The catalyst in the isomerization zone is free of chloride, and the streams including effluent from the isomerization zone may be passed to a steam cracker without requiring chloride removal.Type: GrantFiled: May 1, 2014Date of Patent: April 5, 2016Assignee: UOP LLCInventors: Mark P. Lapinski, Matthew Lippmann

Suppression of the iC4 hydrocarbons does not occur, allowing the iC4 hydrocarbons to be isomerized in the same isomerization zone as the iC5 hydrocarbons and iC6 hydrocarbons.Type: GrantFiled: May 1, 2014Date of Patent: April 5, 2016Assignee: UOP LLCInventors: Mark P.

Patent number: 9302957Abstract: A process for controlling a yield of an isomerization zone. Prior to entering the isomerization zone, C6 cyclic hydrocarbons are removed from a feed stream. Disproportionation reaction selectivity is observed which produces valuable C3 hydrocarbons and C4 hydrocarbons. Also, a higher ring opening conversion of C5 cyclic hydrocarbons is observed. The disproportionation reactions and the ring opening reactions may be selectively controlled by adjusting an amount of C6 cyclic hydrocarbons passed into the isomerization zone.Type: GrantFiled: May 1, 2014Date of Patent: April 5, 2016Assignee: UOP LLCInventors: Mark P.

Publication number: 20160038899Abstract: A riser includes a housing in communication with a entry conduit and an exit conduit. The housing is defined by a holdup chamber having a volume of between about 1133 liters and about 45307 liters. The riser is designed to receive a hydrocarbon feed and a catalyst. An apparatus for fluid catalytic cracking includes a riser in fluid communication with a reactor vessel. A hydrocarbon feed stream and a catalyst travel through a first section of the riser at a first velocity of between about 1.5 msec to about 10 msec and through a second section of the riser at a second velocity of more than about 15 msec. A process for fluid catalytic cracking uses a riser with a holdup chamber. A hydrocarbon feed and a catalyst decrease in velocity in the holdup chamber to between 1.5 msec and 10 msec.Type: ApplicationFiled: October 22, 2015Publication date: February 11, 2016Inventors: Patrick D. Walker, Matthew Lippmann, Mark Schnaith

Patent number: 9193921Abstract: A process for transalkylating a coal tar stream is described. A coal tar stream is provided, and is fractionated to provide at least one hydrocarbon stream having polycyclic aromatics. The hydrocarbon stream is hydrotreated in a hydrotreating zone, and then hydrocracked in a hydrocracking zone. A light aromatics stream is added to the hydrocracking zone.

Patent number: 9193644Abstract: A process for selectively dealkylating aromatic compounds includes providing a coal tar stream comprising aromatic compounds and hydrotreating the coal tar stream to reduce a concentration of one or more of organic sulfur, nitrogen, and oxygen in the coal tar stream, and to hydrogenate at least a portion of the aromatic compounds in the coal tar stream. The process further includes hydrocracking the hydrotreated coal tar stream to further hydrogenate the aromatic compounds and to crack at least one ring of multi-ring aromatic compounds to form single-ring aromatic compounds. The single-ring aromatic compounds present in the hydrocracked stream are then dealkylated to remove alkyl groups containing two or more carbon atoms.Type: GrantFiled: May 21, 2015Date of Patent: November 24, 2015Assignee: UOP LLCInventors: Stanley J.

Patent number: 9079816Abstract: A process for producing alkylated aromatic compounds includes pyrolyzing a coal feed to produce a coke stream and a coal tar stream. The coal tar stream is hydrotreated and the resulting hydrotreated coal tar stream is cracked. A portion of the cracked coal tar stream is separated to obtain a fraction having an initial boiling point in the range of about 60° C. to about 180° C., and an aromatics-rich hydrocarbon stream is extracted by contacting the fraction with one or more solvents. The aromatics-rich hydrocarbon stream is contacted with an alkylating agent to produce an alkylated aromatic stream, or the aromatics-rich hydrocarbon stream is reacted with an aliphatic compound or methanol in the presence of a catalyst to produce a methylated aromatic stream. The alkylated aromatic stream, the methylated aromatic stream, or both are separated into at least a benzene stream, a toluene stream, and a xylenes stream.Type: GrantFiled: August 22, 2014Date of Patent: July 14, 2015Assignee: UOP LLCInventors: James A.
