Reflux divider is a valve located between condenser and top of the column. It helps in maintaining the desired reflux ratio in distillation column. It is usually located between the top tray of the column and the condenser. The condenser is usually updraft (vapor flows up from the column, condenses, and flows back down the inside of the condenser, countercurrent with the vapor, back to the top of the column).
In these units, the reflux is adjusted by means of a valve on the outlet connection. When the valve is fully opened the divider is set to total distillate off-take, Since the reflux pipe is higher than the outlet connection, by regulating the valve, the reflux ratio can be continuous adjusted up to total.
