How to Troubleshoot a Distillation Column
Distillation is a procedure where an experimenter separates a mixture of liquids based on their tendency to vaporize. Generally, each liquid vaporizes at a different temperature. A distillation column is utilized during fractional distillat... Read More »

What is dumping in a distillation column?
This phenomenon is caused by low vapour flow. The pressure exerted by the vapour is insufficient to hold up the liquid on the tray. Therefore, liquid starts to leak through perforations. Excessive weeping will lead to dumping. That is the l... Read More »
