Publication number: 20130020054Abstract: 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.Type: ApplicationFiled: September 5, 2012Publication date: January 24, 2013Inventors: H. Lynn Tomlinson, William Manning, William Schaefer, Tsungani Record
