The occurrence of pressure drop
Thread Content
May I ask what factors can cause an increase in the pressure drop inside a distillation tower?
Operation aspects: (1) High air supply load； (2) High proportion of light components in the feed; other reasons: blockage of some tray plates
Additional note: All factors that increase the thickness of the liquid layer on the board； Effect of feed.
An increase in the evaporation rate at the bottom of the tower can also lead to an increase in pressure drop. In the case of vacuum distillation, an increase in the degree of vacuum will likewise result in an increase in pressure drop
