  • Alkylation unit and method of modifying
    Patent number: 8912382
    Abstract: One exemplary embodiment can be a method of modifying an alkylation unit to increase capacity. The method may include combining a first alkylation zone with a second alkylation zone. Generally, the first alkylation zone includes a first settler having a height and a width. Typically, the width is greater than the height. In addition, the second alkylation zone may have a second settler having a height and a width. Usually, the height is greater than the width.
    Type: Grant

    Date of Patent: December 16, 2014
    Assignee: UOP LLC
    Inventors: Daryl Dunham, Dale James Shields
  • Method for altering an operation of an alkylation unit
    Patent number: 8895798
    Abstract: One exemplary embodiment can be a method for altering an operation of an alkylation unit during a process upset. The method may include blocking an outlet of a settler to a separation zone, and recycling at least a portion of a hydrocarbon stream to the separation zone to prevent an uncontrolled pressure rise in one or more distillation columns during shutdown of an alkylation reactor.

  • Acid alkylation system and process for controlling temperature in a settler
    Patent number: 8747783
    Abstract: One exemplary embodiment can be an acid alkylation system. The system can include a cooler-reactor and a settler. The settler can have a height and a width. Usually, the height exceeds the width. Generally, the cooler-reactor receives a feed of at least one of a stream including an olefin and a stream including an isobutane. Typically, at least a portion of one of the streams is bypassed around the cooler-reactor to the settler to control the temperature within the settler.
