Distillation column is a multi-stage partial vaporization and partial condensation according to the ponents in the mixture volatility in each floor tower board to achieve the separation of a mixture of ponents of the tower gas-liquid contact device, also known as distillation. A plate column and packed column types. According to mode of operation are divided into continuous distillation and batch distillation. Steam from the bottom of the column entry, and the decline in liquid countercurrent contact with the two in contact, the drop in the volatile liquid (low boiling point) components is continuously transferred to the steam. The difficulty of steam volatile (high boiling) component continued to decline in the transfer of liquid, steam the closer the top of the tower, the higher the concentration of its ponents, while the decline in the closer tower bottom liquid, its hard to be more ponents rich set, to ponent separation. Steam rising from the top of the tower into the condenser, the liquid part of the condensate as reflux liquid to return into the distillation tower, the rest is removed as distillate. Tower bottom outflow of liquid, some of which
