Patent number: 10072103Abstract: A system and method for startup of a polyolefin reactor temperature control system having a first reactor temperature control path, a second reactor temperature control path, and a shared temperature control path. In some embodiments, during startup the second reactor temperature control path is configured to allow the temperature of a second reactor to rise due to the heat of the exothermic polymerization reaction occurring within the reactor until reaching a predetermined setpoint temperature. In other embodiments, during startup a first reactor temperature control path is configured to include a heat exchanger used as a cooler, and a second reactor temperature control path is configured to include a heat exchanger used as a heater, to raise the temperature of the second reactor until reaching a predetermined setpoint temperature.Type: GrantFiled: July 11, 2017Date of Patent: September 11, 2018Assignee: Chevron Phillips Chemical Company LPInventors: Timothy O.

Publication number: 20070078237Abstract: An apparatus and method for removing polymer solids from a slurry loop reactor. A discharge conduit having a longitudinal axis and an end section for removing polymer solids from the slurry loop reactor is provided. The discharge conduit is attached to the slurry loop reactor so that the longitudinal axis and at least a portion of an outer wall of the slurry loop reactor form an angle of less than about 90 degrees. The end section includes a first edge and a second edge that extends past at least a portion of an inner wall of the slurry loop reactor into a liquid reactor slurry. Polymer solids contained within the liquid reactor slurry are concentrated on the second edge so that an average polymer solids concentration in the discharge slurry is greater than an average polymer solids concentration of the liquid reactor slurry within the slurry loop reactor.Type: ApplicationFiled: October 5, 2005Publication date: April 5, 2007Inventors: Robert McElvain, John Hottovy, David Burns, Donald Verser, Anurag Gupta, Ralph Romig
