Patent number: 9890096Abstract: 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 higher pressure than the liquid phase hydrofluorination of 1233xf; and wherein the HC1 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: GrantFiled: December 7, 2011Date of Patent: February 13, 2018Assignee: Honeywell International Inc.Inventors: Stephen A. Cottrell, Yuon Chiu, Haluk Kopkalli, Hsueh Sung Tung, Kevin D. Uhrich, Peter Scheidle

Patent number: 8921623Abstract: A process for the production of fluorinated alkanes by contacting a feed stream containing a fluorinated olefin and a reducing agent, preferably with a first amount of catalyst to produce a fluorinated alkane, at a first conversion level, wherein a first effluent stream contains unreacted fluorinated olefin and reducing agent; and contacting the first effluent stream under conditions effective to produce a higher level of conversion than said conversion level.Type: GrantFiled: February 25, 2011Date of Patent: December 30, 2014Assignee: Honeywell Industrial Inc.Inventors: Michael Van Der Puy, George R. Cook, Peter H. Scheidle, Kevin D. Uhrich

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.

Patent number: 4880510Abstract: A process for removing color impurities such as dye stuffs from wastewater solutions and simultaneously removing heavy metal contaminants is described. The process includes passing the wastewater solution through an electrolytic cell, having an anode of iron, an iron alloy, or an insoluble iron compound to generate ferrous iron at the anode which then reacts with hydroxide ion generated at the cathode causing a coprecipitation of the impurities with insoluble ferrous hydroxide.Type: GrantFiled: January 5, 1989Date of Patent: November 14, 1989Assignee: Andco Environmental Processes, Inc.Inventor: Kevin D.
