Patent number: 9174928Abstract: Processes for the epoxidation of ethylene are provided in which, following start-up, an epoxidation catalyst is contacted with a feed comprising ethylene, oxygen, carbon dioxide in an amount below 2.0 vol. %, and a chloride moderator to achieve a desired work rate at a first operating temperature T1. The composition of the feed is subsequently adjusted (e.g., by decreasing the ethylene concentration, decreasing the oxygen concentration, increasing the carbon dioxide concentration and/or adjusting the concentration of the chloride moderator) so as to increase the first operating temperature T1 to a second operating temperature T2 while maintaining the desired work rate. As the catalyst activity declines, the composition of the feed is further adjusted so as to maintain the desired work rate at the second operating temperature T2.Type: GrantFiled: April 26, 2012Date of Patent: November 3, 2015Assignee: Shell Oil CompanyInventors: Wayne Errol Evans, Jeffrey Michael Kobe, Marek Matusz

Patent number: 8742146Abstract: The present invention relates to a process for improving the overall selectivity of an EO process for converting ethylene to ethylene oxide utilizing a highly selective EO silver catalyst containing a rhenium promoter wherein following normal operation a hard strip of the chloride on the surface of the catalyst is conducted in order to remove a portion of the chlorides on the surface of the catalyst. Following the hard strip, the catalyst is optionally re-optimized. Surprisingly, it has been found that the selectivity of the catalyst following the hard strip may be substantially higher than the selectivity prior to the hard strip.Type: GrantFiled: December 2, 2011Date of Patent: June 3, 2014Assignee: Shell Oil CompanyInventors: Martin Lysle Hess, Wayne Errol Evans, Jeffery Michael Kobe, Marek Matusz

Publication number: 20120277447Abstract: The present invention relates to a process for improving the selectivity of an EO process utilizing a highly selective EO catalyst. In particular, the present invention is an improvement in the initial operation of a process for manufacturing ethylene oxide by contacting ethylene, oxygen, a chloride moderator and a hydrocarbon co-moderator with a high selectivity silver-containing catalyst at a concentration of carbon dioxide of less than about 2 mole percent, wherein the initial operating temperature is determined by optimization of such initial operating temperature at a level higher than the normal low initial operating temperature that is typically selected to obtain a longer operating cycle.Type: ApplicationFiled: April 26, 2012Publication date: November 1, 2012Applicant: SHELL OIL COMPANYInventors: Wayne Errol EVANS, Jeffrey Michael KOBE, Marek MATUSZ

Publication number: 20080029265Abstract: A combined anti-rotation and flow control tool comprises a tubular housing for connection with an oil production tubing string. A flow port in the side wall of the housing is selectively covered by a collar rotatably mounted on the tubular housing and including corresponding ports therein for selective alignment with the flow ports as the collar is rotated. An anti-rotation mechanism includes a fixed jaw on the tubular housing and a floating jaw on the collar for rotation therewith to vary the overall diameter of the tool as the floating jaw rotates relative to the fixed jaw. The collar and the floating jaw are coupled for movement together so that the flow ports are always in the open position when the anti-rotation mechanism is in a set position anchored against righthand rotation of the tubing string.Type: ApplicationFiled: August 1, 2007Publication date: February 7, 2008Inventors: G.

Patent number: 7278478Abstract: An anchoring tool anchors a tubing string within a surrounding well casing against rotation in either clockwise or counter clockwise directions. The tool includes a tubular housing for connection in line with the tubing string. A fixed jaw is fixedly mounted on the tubular housing and a floating jaw is supported for full rotation about the tubular housing past the fixed jaw. When the floating jaw engages the well casing, the overall diameter of the tool is varied as the fixed jaw is rotated with the tubing string relative to the floating jaw and the surrounding well casing. The tool can be used for anchoring the tubing string to the well casing in either direction while the tool remains down hole in the well casing due to the floating jaw being rotatable past the fixed jaw.Type: GrantFiled: April 27, 2005Date of Patent: October 9, 2007Inventors: G.

Patent number: 6892811Abstract: An anchoring tool is provided for preventing rotation of a tubing string relative to a surrounding well casing in both right and left hand directions of rotation. The tool includes tubular housing for connection in line with the tubing string. A gripping member is supported alongside the housing for rotation about an anchor axis lying substantially parallel to the housing. The gripping member has a profile which increases in radial dimension from a first gripping portion to a second gripping portion thereof. The first gripping portion and the second gripping portion being arranged to grip the surrounding well casing in a retracted position and an extended position respectively. Rotation of the housing with the tubing string relative to the well casing rotates the gripping member in relation to the housing to vary an overall diameter of the anchoring tool within the well casing, thereby preventing further rotation.Type: GrantFiled: December 16, 2002Date of Patent: May 17, 2005Inventors: G.
