How to control pressure

2016-03-23View Original

Thread Content

Given a constant pressure in the reflux drum at the top of the distillation tower, how can the pressure at the tower top be adjusted, and which factor has the greatest impact on this pressure?

The pressure at the top of the distillation tower is generally controlled by adjusting the pressure in the reflux tank

The main factor affecting column pressure is the top load of the column. The actual parameters that reflect this are the top temperature of the tower (including the temperature after cooling) and the reflux rate.
