    • A process and associated apparatus for the cooling of hot fluidized solid particles. The particles flow from a first dense phase fluidized bed into the shell side of a vertically oriented shell and tube heat exchanger where cooling occurs via indirect heat exchange with a cooling medium circulating in the tubes. The extent of cooling is controlled by the varying of the heat transfer coefficient between the tubes and particles in the heat exchanger which are maintained as a second dense phase fluidized bed. The coefficient is varied by varying the quantity of fluidizing gas to the fluidized bed in the heat exchanger. The particles flow freely to and from the first and second dense phase fluidized beds through which the particles recirculate and are backmixed. The process has particular applicability to a combustive regeneration process and most particular applicability to the FCC process.
    • 一种用于冷却热流化固体颗粒的方法和相关设备。 颗粒从第一密相流化床流入垂直取向的壳管式热交换器的壳侧,其中通过与在管中循环的冷却介质的间接热交换进行冷却。 冷却的程度通过保持为第二致密相流化床的热交换器中的管和颗粒之间的传热系数的变化来控制。 通过改变热交换器中流化床的流化气体的量来改变系数。 颗粒自由地流入和流出第一和第二致密相流化床,颗粒通过该流化床再循环并被混合。 该方法特别适用于燃烧再生过程以及对FCC方法的最特别的适用性。
