Publication number: 20120184785Abstract: Disclosed is a process for the manufacture of 1234yf from 1,1,2,3-tetrachloropropene, abbreviated herein as “TCP,” in three integrated steps: (a) the R-1 hydrofluorination of TCP to form 1233xf in the vapor phase; (b) the R-2 hydrofluorination of 1233xf to form 244bb in either the liquid phase or in the liquid phase followed by the vapor phase; and (c) the R-3 dehydrochlorination of the 244bb in either the liquid or the vapor phase to produce 1234yf; wherein the vapor phase hydrofluorination of TCP in step (a) is carried out at a lower pressure than the liquid phase hydrofluorination of 123xf; and wherein the HCl generated during these steps is scrubbed with water to form an acid solution and the organic components are scrubbed with a caustic solution and then dried before further processing.Type: ApplicationFiled: December 7, 2011Publication date: July 19, 2012Inventors: Stephen A.

Publication number: 20120134892Abstract: Disclosed is a process and apparatus for the catalytic hydrogenation of fluoro-olefins to fluorocarbons where the reaction is carried out in a multi-tube shell and tube reactor. Reactions involving hydrogenation of fluoro-olefins are typically exothermic. In commercial processes where a fluoro-olefin CnH2n-xFx to CnH2n-x2Fx is hydrogenated (e.g., hexafluoropropylene to 236ea, 1225ye to 245eb, and the like), inadequate management or control of heat removal may induce excess hydrogenation, decomposition and hot spots resulting in reduced yields and potential safety issues. In the hydrogenation of fluoro-olefins, it is therefore necessary to control the reaction temperature as precisely as practical to overcome challenges associated with heat management and safety.Type: ApplicationFiled: January 31, 2012Publication date: May 31, 2012Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Haluk Kopkalli, Yuon Chiu, Orlando George Rodrigues, Gus Cerri, Hsueh Sung Harry Tung, Stephen A.

Patent number: 8069110Abstract: A method and system for facilitating trading of financial instruments in a market are provided. The system comprises a server and an interface. The interface is configured to enable buy orders and sell orders to be entered. Each order has a price, a volume, and an entry time and relates to a respective futures contract. The server is configured to match received buy orders having a first price to received sell orders having the first price. The match is effected by ensuring that the prices match, and then using the volume and entry time for each buy order and each sell order to assign a weight of time relative to volume, and then using the weights to determine each match. The server uses the matches to complete respective trades. The weights may be adjusted based on market conditions.Type: GrantFiled: February 12, 2010Date of Patent: November 29, 2011Assignee: NYSE Life Administration and ManagementInventor: Stephen Cottrell

Patent number: 8034308Abstract: A multi-stage, multi-tube, shell-and-tube reactor which contains reaction zones and interstage temperature control (cooling/heating) zones in series. The reactor has at least two types of zones which both contribute to removing or supplying heat to the system depending on the system's need. The reactor will have a group of reaction zones which contain tubes packed with catalyst to progress the reaction and remove or supply heat simultaneously. There are also a number of interstage temperature control (cooling/heating) zones which are designed to supply or remove heat to or from the system. The positioning, number, and design of the zones will depend on the amount of temperature control desired and exothermic or endothermic nature of the processes to be conducted in the reactor.Type: GrantFiled: June 9, 2009Date of Patent: October 11, 2011Assignee: Honeywell International, Inc.Inventors: Yuon Chiu, Stephen A.

Publication number: 20110105807Abstract: Disclosed is a process for the manufacture of HFO-1234yf from TCP in three integrated steps that include hydrofluorination of TCP (tetrachloropropene) to HCFC-1233xf in the vapor phase followed by hydrofluorination of HCFC-1233xf to HCFC-244bb in the liquid phase which is then followed by dehydrochlorination in liquid or vapor phase to produce HFO-1234yf. The vapor phase hydrofluorination is carried out at a higher pressure than the liquid phase hydrofluorination, thereby eliminating the need for compression and/or intermediate recovery. Also, any HCl generated from this reaction is fed to the liquid phase hydrofluorination section to promote agitation and mixing. This results in a more economical process from an initial capital and operating cost versus conducting the 3-steps sequentially.Type: ApplicationFiled: November 3, 2009Publication date: May 5, 2011Applicant: Honeywell International Inc.Inventors: Haluk Kopkalli, Yuon Chiu, Stephen A.
