Heat removal from the distillation tower
Thread Content
What is the heat amount for the entire distillation column in a typical catalytic unit? For example, what does 23% heat recovery from the tower top reflux mean? (What percentage of 23%)
The total heat in the distillation column varies depending on the different raw materials and processing methods; it is necessary to determine this value through heat balance calculations. The 23% you mentioned is the proportion of the total reflux heat in the fractionation tower. 23.0% of the total heat from the slurry, middle section, top circulation, and cold reflux.
Now, different catalytic units are designed for different feed materials, so there are also differences in heat extraction
