The impact of tower diameter on distillation towers
Thread Content
I would like to ask everyone: what is the main impact of tower diameter on distillation?
Processing capacity, which is basically the feed rate
The diameter of the tower represents its processing capacity; if the feed rate remains constant, increasing the tower diameter also leads to an increase in the size of the tray specifications and the type of distributor. More packing is used, which increases the surface area for material contact, and this can improve the product distillation efficiency. However, changing the tower diameter requires recalculating the number of trays, the type of distributor, and the amount of packing needed.
The operating parameter of temperature generally remains unchanged, as does the tower pressure; however, the reflux rate can change. If the tower diameter increases too much, it is necessary to recalculate the location of the distillation outlet, as well as the positions of the tray and packing.
