Main uses of continuous distillation tower
       Due to the frequent starts and stops of intermittent distillation, the equipment utilization rate is low, the operation is inconvenient, and it is difficult to obtain high-purity products. Therefore, intermittent distillation is generally only used when continuous distillation is inconvenient. Most industries use continuous distillation. Through scientific calculations, continuous distillation towers can achieve stable operation for the distillation of binary components, and can obtain high-purity products with high output, low energy consumption, and compact equipment structure.

Device composition and working principle
       The feed liquid is injected into the high-level tank with a pump (or sucked in by vacuum) and measured by a rotor flow meter, then enters the preheater. The feed liquid is preheated to the bubble point and enters the tower. The bottom of the tower is heated by the reboiler. The steam at the top of the tower directly enters the total condenser. The condensate passes through the pressure stabilizer, and part of it is refluxed. The concentration is measured by a specific gravity meter, and then it enters the cold unloader and is lowered to normal temperature before entering the receiving tank.
