    • 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. The cooling system further including a plenum connected to the lower portion of the at least one downcomer; the plenum in fluid communication with the at least one downcomer wherein the coolant remains in the substantially liquid phase. Additionally, the cooling system includes at least one riser having a length and extending upward from the plenum; the at least one riser in fluid communication with the plenum wherein a portion of the coolant vaporizes to provide a boiling heat transfer surface on the at least one riser.
    • 本发明涉及一种用于从费 - 托(F-T)浆料反应器中除去热量的冷却系统。 所述冷却系统包括具有上部,下部和直径的至少一个降液管; 所述至少一个降液管设置在所述FT反应器内以预定速度向下输送冷却剂,所述至少一个降液管在所述FT反应器内延伸一段长度,其中所述冷却剂被引入所述至少一个 基本上液相的降液管; 所述至少一个降液管的直径和所引入的冷却剂的压力协调以增加冷却剂速度,从而在所述至少一个降液管中产生背压,以将所述冷却剂沿着所述至少一个降液管的长度维持在基本上液相中。 所述冷却系统还包括连接到所述至少一个降液管的下部的增压室; 所述增压室与所述至少一个降液管流体连通,其中所述冷却剂保持在基本上液相中。 另外,冷却系统包括至少一个具有长度并从气室向上延伸的立管; 所述至少一个提升管与所述增压室流体连通,其中所述冷却剂的一部分蒸发以在所述至少一个提升管上提供沸腾的传热表面。
