Patent number: 9433917Abstract: A process for producing alkylated hydrocarbons includes the steps of: (a) combining a first feed stream comprising an olefin and an isoparaffin with an alkylation catalyst stream in a first alkylation reactor, (b) removing heat of reaction from the first alkylation reactor, (c) passing an effluent of the first alkylation reactor to a first reaction zone of a second alkylation reactor operating adiabatically to thereby form a first reaction zone effluent, (d) passing the first reaction zone effluent to a second reaction zone of the second alkylation reactor for mixture with a second feed stream comprising an olefin and an isoparaffin, and (e) passing an effluent of the second alkylation reactor to a settler for separation into a hydrocarbon stream and an alkylation catalyst effluent stream. An alkylation unit for carrying out the process is also disclosed.Type: GrantFiled: March 26, 2015Date of Patent: September 6, 2016Assignee: UOP LLCInventors: Mark L. Gravley, Martyn E. Pfile

Patent number: 6709638Abstract: A system and/or process for removing water from an alkylation catalyst mixture of an alkylation process is disclosed. The process includes passing an alkylation reaction zone effluent to a settler for separation into a hydrocarbon phase and a catalyst mixture phase; passing at least a portion of the hydrocarbon phase, as a settler effluent stream containing alkylate, water, HF and volatility reducing additive, to a first separator; removing and condensing a first overhead stream from the first separator thereby forming an HF/water stream; passing the HF/water stream to a second separator for separation into a modified HF stream containing HF and volatility reducing additive and into an HF/water azeotrope stream containing HF and water; using the modified HF stream as a part of the alkylation catalyst mixture and; removing water from the system by removing the HF/water azeotrope stream from the second separator.Type: GrantFiled: February 21, 2003Date of Patent: March 23, 2004Assignee: ConocoPhillips CompanyInventors: Bruce B. Randolph, Curtis B. Wood, Martyn E. Pfile

Patent number: 5237115Abstract: A novel integrated olefin processing scheme is provided where olefins and paraffins are processed to produce high octane gasoline blending components. The integrated process involves the dehydrogenation of paraffin compounds to olefin compounds and the processing of olefins by hydroisomerization to produce hydroisomerate streams which are subsequently etherified. Those olefin compounds which are not etherified pass to an alkylation process where they are alkylated with branched chain paraffin compounds to produce an alkylate product.Type: GrantFiled: June 16, 1992Date of Patent: August 17, 1993Assignee: Phillips Petroleum CompanyInventors: Donald J.
