  • Patent number: 9266082
    Abstract: The present invention is directed to a cooling system for removing heat from a Fischer-Tropsch (F-T) slurry reactor. The cooling system including a downcomer disposed within the F-T reactor to deliver a coolant downward through the F-T reactor at a predetermined velocity. The downcomer and the pressure of the introduced coolant cooperate to increase the coolant velocity, thereby maintaining the coolant in the substantially liquid phase in the downcomer. The cooling system further includes a plenum connected to the downcomer, wherein the coolant remains in the substantially liquid phase. Additionally, the cooling system includes at least one riser extending upward from the plenum, wherein a portion of the coolant vaporizes to provide a boiling heat transfer surface on the at least one riser.

  • Patent number: 8318102
    Abstract: The present invention is directed to a cooling system for removing heat from a Fischer-Tropsch (F-T) slurry reactor. The cooling system including at least one downcomer having an upper portion, a lower portion, and a diameter; the at least one downcomer disposed within the F-T reactor to deliver a coolant downward through the F-T reactor at a predetermined velocity, the at least one downcomer extending a length within the F-T reactor wherein the coolant is introduced into the upper portion of the at least one downcomer in a substantially liquid phase; the diameter of the at least one downcomer and the pressure of the introduced coolant cooperate to increase the coolant velocity thereby generating backpressure in the at least one downcomer to maintain the coolant in the substantially liquid phase along the length of the at least one downcomer.

  • Patent number: 5975480
    Abstract: A motor mount for a motor having an elongate drive shaft. The motor mount includes a base having a generally planar surface. At least one elongate rail is disposed at the surface of the base. A motor carriage plate has a generally planar bottom surface disposed approximate to and generally parallel to the surface of the base. The motor carriage plate has at least one rail engaging surface disposed at an angle to the bottom surface. The motor mount includes a motor carriage fastener for fastening the motor to the motor carriage plate. A fastener is provided for attaching the motor carriage plate to the base plate such that the rail engaging surface engages the elongate rail.
