Patent number: 8207387Abstract: Provided is a method of producing polypropylene comprising contacting an oxygenate stream with a molecular sieve to form an olefin stream comprising propane, propylene and dimethylether; introducing the olefin stream into a propylene rectification tower possessing from less than 200 theoretical stages; withdrawing from the propylene rectification tower a bottom stream comprising dimethylether, a sidestream comprising propane, and an overhead stream comprising propane and propylene; introducing the overhead to a condenser to accumulate a propylene-rich stream; passing the propylene-rich stream to a splitter to produce (i) a first propylene stream that is introduced into a polypropylene reactor to contact a polyolefin catalyst, and (ii) a second propylene stream that is re-introduced into the rectification tower, the first and second propylene streams introduced at a desirable ratio; and recirculating the dimethylether stream to contact the molecular sieve.Type: GrantFiled: May 3, 2010Date of Patent: June 26, 2012Assignee: Exxonmobil Chemical Patents Inc.Inventors: Gerald G. McGlamery, Jr., Lawrence C. Smith, Jennifer L. Bancroft

Patent number: 7989669Abstract: This invention is directed to a process for producing one or more olefins from an oxygenate feed. According to the invention, an oxygenate stream is provided and a recycle stream is added to the oxygenate stream to form a feed stream to an oxygenate-to-olefin conversion system. The recycle stream comprises (i.e., contains) propane and dimethyl ether.Type: GrantFiled: February 20, 2008Date of Patent: August 2, 2011Assignee: ExxonMobil Chemical Patents Inc.Inventors: Gerald G. McGlamery, Jr., James H. Beech, Jr., Michael P. Nicoletti, Cornelis F. Van Egmond

Patent number: 7893310Abstract: This invention is to a process for separating condensed water and entrained solids from an olefin stream so that fouling of the separation equipment by the entrained solids is reduced or eliminated. The process involves injecting an antifouling agent into a water condensing or quench system in an amount to maintain a zeta potential of fouling liquid and a zeta potential of the surface of the quench system both in a positive range or both in a negative range.Type: GrantFiled: January 31, 2008Date of Patent: February 22, 2011Assignee: ExxonMobil Chemical Patents Inc.Inventors: Gerald G. McGlamery, Jr., Michael P. Nicoletti, Thomas H. Colle
