  • Method of column control
    Patent number: 11225444
    Abstract: A method of column control includes: passing a feed stream and a make-up stream through a column; withdrawing an overhead fraction from the column; purging at least a portion of the overhead fraction; cooling at least a portion of the overhead fraction in a heat exchanger and passing it through a reflux drum; withdrawing a purge stream and a distillate stream from the reflux drum, wherein the distillate stream has a constant flow rate; recycling at least a portion of the distillate stream back to the column; and passing at least a portion of the distillate stream to a downstream process.
    Type: Grant
    Filed: December 19, 2017
    Date of Patent: January 18, 2022

  • Method for Temperature Control in a Bubble Column Reactor for Selective 1-Hexene Production
    Publication number: 20200139334
    Abstract: A method of temperature control includes: passing a feed stream comprising ethylene through a reactor at a feed location; withdrawing an outlet steam comprising linear alpha olefins from the reactor; passing the outlet stream through a condensate vessel, wherein the outlet stream is split into a vapor fraction and a liquid fraction within the condensate vessel; withdrawing the vapor fraction from the condensate vessel and recycling it back to the feed stream; and withdrawing the liquid fraction from the condensate vessel and injecting it into the reactor at an injection location.
