Patent number: 10703979Abstract: The present invention is directed towards modifying the internals of the reactor section of a fluidized coke reactor such that the majority of the hydrocarbon feed will react in the core region of the reactor section and that any hydrocarbon vapour that is produced in the annular region will be released into the core region. Therefore, the present invention reduces the residence time of vapour immediately flashed from the injected hydrocarbon feed, resulting in reduced secondary vapour phase cracking.Type: GrantFiled: February 12, 2019Date of Patent: July 7, 2020Assignee: SYNCRUDE CANADA LTD.Inventors: Michael Wormsbecker, Jennifer McMillan, Craig McKnight, Jason Wiens

Publication number: 20190161684Abstract: A process for converting a heavy hydrocarbonaceous feedstock to liquid products is provided comprising introducing the hydrocarbonaceous feedstock into a fluid coker comprised in part of a fluidized bed of heated coke particles, the fluidized bed having a high velocity core region of heated coke particles and a low velocity annular region of unreacted hydrocarbon and coke particles using a plurality of high thrust nozzles and reacting the hydrocarbonaceous feedstock with the heated coke particles in the fluid coker to produce the liquid products.Type: ApplicationFiled: November 27, 2018Publication date: May 30, 2019Inventors: JENNIFER McMILLAN, CRAIG McKNIGHT, MICHAEL WORMSBECKER, JASON WIENS, BRIAN KNAPPER

Patent number: 9889420Abstract: A feed injector for a circulating fluid bed reactor is fitted with a discharge nozzle with a circular, radially notched discharge orifice to improve the surface-to-volume ratio of the spray pattern formed by the nozzle. The feed injector is useful for injecting fluids into various types of circulating fluid bed reactors in which good contact between the components of the fluidized bed and the injected fluid is required. It is particularly useful in fluid coking reactors.Type: GrantFiled: December 1, 2015Date of Patent: February 13, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Brian Allen Knapper, Christian Wolfgang Schroeter, Robert William Skwarok, Nicholas Prociw, Jennifer McMillan

Patent number: 9738836Abstract: The liquid feed nozzle assemblies for a circulating fluid bed reactor comprise (i) a throttle body premixer to combine liquid feed with atomization steam to form a liquid feed/steam mixture comprising gas bubbles in liquid; (ii) a conduit connected to the premixer and to a discharge nozzle to convey a flow of the liquid/steam mixture created by the premixer to the nozzle body; (iii) a discharge nozzle connected to the flow conduit to shear the liquid feed/steam mixture to create liquid feed droplets of reduced size and (iv) a disperser at the outlet of the discharge nozzle to provide a spray jet of liquid feed having an increased surface area relative to a cylindrical jet. The nozzle assembles are particularly useful in fluid coking units using heavy oil feeds such a tar sands bitumen.Type: GrantFiled: July 29, 2015Date of Patent: August 22, 2017Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Kevin Reid, Jennifer McMillan, Konstantin Pougatch, Martha E. Salcudean

Publication number: 20160312126Abstract: A fluid coking process is operated in a fluidized bed coking reactor in which a plurality of heavy oil inlet nozzles are arranged in a number of rings around the periphery of the dense bed reaction section at vertically spaced elevations. A heavy oil feed is injected with atomization steam through the nozzles into the fluidized. bed, operating at a lower steam-to-oil ratio for the upper ring or rings of nozzles than for the lower ring or rings.Type: ApplicationFiled: March 30, 2016Publication date: October 27, 2016Inventors: Michael Wormsbecker, Jason S. Wiens, Jennifer McMillan, Craig A. McKnight, Brian A. Knapper
