Patent number: 10702798Abstract: A process for treating an ionic liquid containing waste stream is described. If there is a liquid waste stream, the liquid waste stream is introduced into a liquid treatment zone. The ionic liquid in the liquid waste stream is neutralized. The concentration of the ionic liquid in the liquid waste stream is determined, and the allowed concentration of the ionic liquid in the liquid waste stream is determined. The concentration of the ionic liquid in the neutralized liquid waste stream is reduced to the allowed concentration, and the liquid waste stream having the allowed concentration is released. If there is a vapor waste stream, the vapor waste stream is introduced into a vapor treatment zone. The vapor waste stream is treated to form a treated vapor waste stream, and the treated vapor waste stream is released to a plant vapor treatment zone.Type: GrantFiled: October 23, 2015Date of Patent: July 7, 2020Assignee: UOP LLCInventors: Eric Leeton, Gregory J. Schrad, David S. Lafyatis, Matthew Lippmann, Douglas A. Nafis

Patent number: 10618858Abstract: A method of alkylating a hydrocarbon stream including: providing a feed stream that includes hydrocarbons and ionic liquid catalyst; passing the feed stream through a low efficiency mixer to create a mixed stream, whereby the low efficiency mixer creates droplets within the feed stream that are primarily within a predetermined size range; passing the mixed stream and an olefin stream into a reactor; performing an alkylation reaction within the reactor, thereby forming a reacted stream; and separating the reacted stream into a settled ionic liquid catalyst stream and a hydrocarbon stream through the use of at least one hydrocyclone.Type: GrantFiled: July 22, 2016Date of Patent: April 14, 2020Assignee: UOP, LLCInventor: Eric Leeton

Patent number: 10584079Abstract: An alkylation process and apparatus are described. The alkylation process includes pre-mixing a paraffin stream with an ionic liquid catalyst stream from a settler. The premixed paraffin and ionic liquid catalyst stream is mixed in a low-efficiency pump to form a paraffin and ionic liquid catalyst mixture. An olefin feed stream is introduced into a riser reactor. The paraffin and ionic liquid catalyst mixture is introduced into the riser reactor to form a reaction mixture comprising alkylate and the ionic liquid catalyst. The reaction mixture is separated in a settler into an ionic liquid catalyst stream and a hydrocarbon stream.Type: GrantFiled: January 23, 2018Date of Patent: March 10, 2020Assignee: UOP LLCInventor: Eric Leeton

Patent number: 10384988Abstract: The present invention involves processes and equipment for handling chloride in an ionic liquid alkylation system. The processes involve not only breaking down the organic chloride to active HCl for ionic liquid activation, but also recovering HCl in the effluent downstream to maintain the HCl requirements while also reducing HCl emissions. This equipment may be used in conjunction with an isomerization reaction zone which is integrated into the ionic liquid alkylation process to further isomerize n-paraffins to isoparaffins for recycle to the alkylation reaction zone.Type: GrantFiled: November 8, 2016Date of Patent: August 20, 2019Assignee: UOP LLCInventors: Kurt Detrick, Douglas A. Nafis, David A. Wegerer, Eric Leeton, Trung Pham

Patent number: 9329106Abstract: Methods, apparatuses, and kits for collecting chemical samples are provided. In one embodiment, a method for collecting a sample of a chemical from a vessel includes connecting a sampling chamber and a removal chamber in fluid communication with the vessel and flowing a liquid phase of the chemical from the vessel through the sampling chamber and the removal chamber. The method isolates a first volume of the liquid phase in the sampling chamber and removes a second volume of the liquid phase from the removal chamber. Further, the method includes establishing fluid communication between the sampling chamber and the removal chamber and filling the removal chamber with a portion of the first volume to form a vapor phase of the chemical in the sampling chamber. Also, the method includes isolating the sample including the vapor phase and a remaining portion of the liquid phase in the sampling chamber.Type: GrantFiled: February 28, 2014Date of Patent: May 3, 2016Assignee: UOP LLCInventor: Eric Leeton
