What is the principle of dehydration in a vacuum distillation tower?
Thread Content
Some oils need to be sent to a vacuum distillation tower for dehydration. May I ask what the principle behind this is? Is the water removed by creating a vacuum?
I’d like to hear the details about pressure tower dehydration. . . Listen to the experts’ answers.
Dehydration in a vacuum distillation tower relies on the fact that water has a lower boiling point at lower pressures (below atmospheric pressure), allowing it to volatilize more easily; water is then separated from the oil products through distillation or flashing.
