ABSTRACT:
A method of cooling a hot particulate material, such as calcined petroleum coke, is described.
The stream of hot particulate material is split as it leaves the device or calciner in which it has been heated. A major portion of it, such as about 80-90%, is dropped directly into a tank of hot water. This material is then separated from the hot water while simultaneously being transferred to a cooling device (such as a rotary cooler) by a suitable conveyor system. The minor portion of hot material is transferred directly from the calciner to the cooling device. In the cooling device, the residual heat content in this hot, minor portion of particulate material is used to drive off the remaining water or moisture contained in the quenched major portion of material.
