Plate tower, dear teachers, please help answer this
Thread Content
The difference lies in whether the heat is extracted from the lower trays of a plate tower and then returned to the upper trays, or whether it is extracted from the upper trays and then returned to the lower trays. For example, heat may be extracted at layer 20 and returned to layer 22. Extract 20 layers and return to 18 layers – what are the differences and advantages/disadvantages of these two designs?
It’s quite tricky to pronounce; I’m not sure what technique is used to do this. As I understand it, the process mentioned above is called distillation, and it helps to increase the purity of what’s above. The process of moving things from below upward is called distillation, and it helps to increase the purity of the material below
It’s mainly classified based on light and heavy components
Intermediate heating and cooling are used in different situations; heating is commonly applied in the stripping section, while cooling is used in the distillation section； Or, for the purpose of extraction, heating is used to vaporize and remove the light components; this is how crude oil distillation towers work
