distillation column reflux unit System composition and working principle
A typical reflux system includes the following key components:
distillation column reflux unit of Condenser: located at the top of the tower, it condenses rising steam into liquid.
distillation column reflux unit of Reflux Drum: stores condensate to achieve gas-liquid separation.
distillation column reflux unit of Reflux Pump: Pressurize some of the condensate and send it back to the top of the tower.
distillation column reflux unit of Control system: Adjust the reflux ratio (the ratio of reflux liquid volume to extraction volume) to meet the requirements of different working conditions
