Vacuum distillation tower
Thread Content
Is a tower diameter of 1200 and a gas-phase diameter of 420 for a vacuum distillation tower reasonable?
It’s not just a bit thick – it’s extremely thick. Consider using a side line for extraction, and installing a condenser at the top (a packing-type condenser can be used in place of a conventional heat exchanger). This way, the gas pipe used for vacuum extraction will be much thinner. The cooling source for condensation can be obtained by exchanging heat with the material from the side line, which also serves to recover heat. This approach can be applied to conventional distillation towers as well
The process engineering field must be taken seriously; not every tower should be designed as a distillation tower……
It depends on whether you do the calculation yourself or get it from a distillation company; if it’s provided by a distillation company, it’s usually based on certified calculations. In the case of negative pressure, the diameter of the gas phase is determined by the gas flow rate.
