Publication number: 20140379894Abstract: Connectivity is tested using different locations and contexts selected from different possible failure zones. The failure zones may include: client failure zones; Internet failure zones; and online service failure zones. The results relating to different connectivity tests performed using the different failure zones are correlated and analyzed in an attempt to determine a root cause of the connectivity issue. For example, the root cause may be determined to be a configuration problem of the client, a problem with the client's networking equipment, an ISP problem, an Internet backbone problem; a problem of the online service, and the like. Different contexts may also be used when performing the tests. These results may be compared to the other connectivity test results. The results from the tests may be provided to the client experiencing the problem. Aggregated test results may also be used to detect service wide issues and trigger an alert.Type: ApplicationFiled: June 21, 2013Publication date: December 25, 2014Inventors: Nicole Allen, Zhipeng Zhao, Zhengwen Zhu, Bradley Hughes, Dionicio Avila, Shawn McGrath, Jason Nelson, John Tait, Aaron Whitney

Publication number: 20070142576Abstract: A polyolefin production system, comprising a polymerization reactor (such as a polyethylene loop slurry reactor) and a fractionation system that receives reactor effluent processed in a diluent/monomer recovery system for recycle to the reactor and to suppliers. A conduit diverts a portion of a reflux flow comprising monomer, such as ethylene, from within the fractionation system to the polymerization reactor, providing for less venting of monomer, such as ethylene, to the supplier. Accordingly, monomer yield is advantageously increased, as the monomer returned to the reactor displaces monomer feedstock to the reactor. The reflux flow may originate from a condensed overhead lights from a diluent recycle column disposed in the fractionation subsystem. The diluent recycle column may receive a stream comprising diluent and monomer as feed from the diluent/monomer recovery subsystem, and may receive the non-diverted portion of the reflux flow as reflux.Type: ApplicationFiled: December 21, 2005Publication date: June 21, 2007Inventors: John Tait, Robert Murphy, Michael Watts, Anurag Gupta

A method for transferring polymer within a polymerization system comprising conveying the polymer from a reactor to a flash chamber via a pressure differential between the reactor and the flash chamber and purging interstitial gases from the polymer prior to conveying the polymer from the sash chamber to a purge column. A method for transferring polymer within a polymerization system comprising conveying the polymer from a flash chamber directly to a purge column via a pressure differential between the flash chamber and the purge column.Type: ApplicationFiled: August 25, 2006Publication date: December 21, 2006Applicant: Chevron Phillips Chemical Company LPInventors: Robert McElvain, John Hottovy, Bryan Garner, Gregory Hendrickson, John Tait

Publication number: 20050034968Abstract: Polymer solids are maintained in an intermediate pressure zone for a desired polymer solids residence time and then transferred to a purge zone or other lower pressure zone. An increase in the polymer solids residence time in the intermediate pressure zone allows more diluent to flash or separate, thereby avoiding or reducing the need for a low pressure flash zone. A fluff chamber may be disposed between the intermediate pressure zone and a lower pressure zone. A transporter tank may be used to transport polymer solids after the intermediate pressure zones.Type: ApplicationFiled: September 23, 2004Publication date: February 17, 2005Inventors: Thomas Reid, Scott Kufeld, John Tait, David Burns, Donald Verser
