Main equipment of distillation tower
       The main equipment in the distillation process includes: distillation tower, reboiler, condenser, reflux tank and conveying equipment. The distillation tower is bounded by the feed plate, with the upper part being the distillation section and the lower part being the extraction section. After some temperature and pressure feed liquid enters the distillation tower, the light components are gradually concentrated in the distillation section. After leaving the top of the tower, they are condensed and enter the reflux tank. One part is used as the top product (also called distillate), and the other part is sent into the tower as reflux liquid. The purpose of the reflux liquid is to replenish the light components on the tray and make the liquid on the tray consist. The main equipment in the distillation process includes: distillation tower, reboiler, condenser, reflux tank and conveying equipment. The distillation tower is bounded by the feed plate, with the upper part being the distillation section and the lower part being the extraction section. A part is heated by the reboiler and returned to the tower to provide some amount of continuously rising steam flow for the distillation operation.
