Vacuum pumping issues in the vacuum distillation tower
Thread Content
After the substances at the top of the vacuum distillation tower condense, there is no non-condensable gas left; in this case, where should the vacuum pump be connected? Is it from the reflux tank, or is the vapor at the top of the tower taken as the output and then condensed back into the reflux tank?
Connected to the top of the reflux tank, behind the condenser
The condenser flows down into the return tank and is then pumped out using an HVP-type high-vacuum discharge pump.
The condenser and the reflux tank – mainly, a vacuum balance tube is installed in the condenser and the reflux tank
