Patent number: 9187384Abstract: This invention is directed to an improvement in the process for the production of alkylaromatic compounds that results in lower levels of residual unreacted materials in the final product. This invention comprises: 1) alkylation of an aromatic compound with an alkylating agent and a catalyst to produce an effluent stream comprising an alkylaromatic compound and unreacted materials; 2) heating the effluent stream; 3) stripping the effluent stream in a stripping device in the presence of steam; 4) separating a stripping stream from the stripping device, the stripping stream rich in unreacted materials; and 5) separating a product stream from the stripping device, the product stream rich in alkylated aromatic compound.Type: GrantFiled: December 13, 2011Date of Patent: November 17, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: Beth A. Winsett, James I. Arnett, II, Kenwyn M. Leger, Brady A. Compton

Patent number: 8884048Abstract: A process for producing esters comprises esterifying an acid or anhydride with an excess of an alcohol to produce a crude ester, recovering excess alcohol from the crude ester and recycling recovered excess alcohol to the esterification reaction together with fresh alcohol. The process is improved by controlling the ratio of the amount of recycled alcohol and the amount of fresh alcohol in dependence on the level of impurities in the recycle alcohol. Further improvements come from feed forwarding fresh alcohol analysis results and from preheating the alcohol before loading into the reactor. Preferably, ester product quality is improved by stripping the alcohol for oxygen removal prior to esterification.Type: GrantFiled: March 7, 2008Date of Patent: November 11, 2014Assignee: ExxonMobil Chemical Patents Inc.Inventors: Nicolaas Anthony De Munck, Brady Compton, John Lyford, IV, Aad Gerrit Oskam

Patent number: 8829227Abstract: Esters produced by the catalyzed reaction of alcohols and acids or anhydrides are neutralized by treatment with an aqueous alkaline alkali metal salt solution in an amount that provides less than a stoichiometric amount of alkali metal salt in relation to the acidity of the crude ester and the amount of water present during the treatment is from 0.8 to 1.4 wt % of water based on the weight of crude ester. When using titanium as the esterification catalyst, the ester resulting from this process contains less than 0.01 ppm by weight of titanium residue, so that it is storage stable when stored in the presence of an antioxidant.Type: GrantFiled: May 24, 2006Date of Patent: September 9, 2014Assignee: ExxonMobil Chemical Patents Inc.Inventors: Brady Compton, John Lyford, IV, Nicolaas Anthony De Munck, Aad Gerrit Oskam, Allen David Godwin, Leendert Johannes Van Dop

Patent number: 8344174Abstract: The efficiency of catalyzed batch esterification reactions is improved by the use of a particular temperature and pressure profile during the reaction cycle. In particular elevated pressure is maintained to prevent alcohol boil off during initial mixing and reaction of the reactants prior to any catalyst addition, and preferably the pressure is reduced rapidly after the desired reaction temperature has been reached.Type: GrantFiled: March 7, 2008Date of Patent: January 1, 2013Assignee: ExxonMobil Chemical Patents Inc.Inventors: Nicolaas Anthony De Munck, Klaas Bandstra, Raphael Frans Caers, Brady Compton, John Lyford, IV, Aad Gerrit Oskam, Berend Jan Van Der Veen

Patent number: 7856540Abstract: Provided are a system and article of manufacture for removing alias addresses from an alias address pool. A plurality of alias addresses are assigned to an alias address pool, wherein the alias addresses in the alias address pool are capable of being dynamically assigned to a device to service I/O requests to the device. An operation is initiated by a process to remove a specified alias address from the alias address pool. An indicator is set to prevent additional processes from removing one alias address from the alias address pool in response to initiating the operation. The specified alias address is removed from the alias address pool.Type: GrantFiled: October 16, 2008Date of Patent: December 21, 2010Assignee: International Business Machines CorporationInventors: Craig Donald Norberg, Scott Brady Compton, Dale Francis Riedy, Jr., Harry Morris Yudenfriend

Patent number: 6389482Abstract: When applications connect to a data pipe, which is located on the same system as the connecting applications, the data pipe is considered a local pipe. That is, local media is used to pipe the data. If, however, an application on a different system is to access the pipe, the pipe is transitioned from a local pipe to a cross-system pipe, in which an alternative non-local media is used to pipe the data. The application causing the transition and any other applications to subsequently connect to the pipe use the cross-system pipe. Any local applications still allocated to the pipe are transitioned, such that they now access the cross-system pipe, instead of the local pipe. Likewise, when an application disconnects from a cross-system pipe, such that all remaining connections to the pipe are local connections, the pipe is transitioned from a cross-system pipe to a local pipe.Type: GrantFiled: August 28, 1997Date of Patent: May 14, 2002Assignee: International Business Machines Corp.Inventors: Roman Anthony Bobak, Scott Brady Compton, Jon Kim Johnson, David Lee Meck, William Robert Richardson

Patent number: 6345312Abstract: A technique for selectively dummying a data pipe transparent to a writer application is provided. A writer application writes data to a local data pipe or a cross-system data pipe and one or more reader applications read data from the data pipe. The technique involves determining when a last reader application of the at least one or more reader applications closes the data pipe before the writer application has completed writing data to the data pipe. Upon determining this condition, further writing of data to the data pipe by the writer application is transparently prevented. While transparently preventing writing to a dummied data pipe, writing of data to a fitting, e.g., for a permanent record, can proceed.Type: GrantFiled: August 28, 1997Date of Patent: February 5, 2002Assignee: International Business Machines CorporationInventors: Roman Anthony Bobak, Scott Brady Compton, Jon Kim Johnson, David Lee Meck, William Robert Richardson

Patent number: 6170045Abstract: Data is written to and read from a shared pipe by applications of multiple systems. At least one shared pipe is located within an external shared memory coupled to one or more central processing complexes. Each of the central processing complexes has one or more operating system images, which controls execution of one or more piping applications. At least one piping application corresponding to at least one operating system image writes data to a shared pipe located in the external shared memory and at least one other application corresponding to one or more other operating system images reads data from the same shared pipe, thereby providing cross-system data piping.Type: GrantFiled: April 30, 1997Date of Patent: January 2, 2001Assignee: International Business Machines CorporationInventors: Roman A. Bobak, Scott Brady Compton, Jon K. Johnson, Alan F. Martens, Max M. Maurer, David Lee Meck, William R. Richardson, Michael Allen Wright
