Reflux is a distillation technique involving the condensation of the distilled product vapors and the return of a portion of the condensate to the distillation system from which it originated reflux is widely used in large-scale, industrial continuous distillation columns as well as in laboratory distillation apparatus setups. How does reflux work in a distillation column. Distillation process is done to achieve a specific level of enrichment to achieve this enrichment level, one must specify a reflux ratio decreasing that reflux ratio (ie, increasing d), has an advantage that the duty of condenser and reboiler decreases, since the load in distillation column decreases (more mass goes out as d increases).
how does reflux work in a distillation column
Bottom product - the product which leaves through the bottom of the column reflux - a portion of vapor from the top of the column which has been condensed to a liquid and returned to the column as a liquid above the top tray reboiler - a heat exchanger at the bottom of the column which boils some of the liquid leaving the column the vapor generated returns to the column at the bottom of the stripping section. In a typical fractional distillation, a liquid mixture is heated in the distilling flask, and the resulting vapor rises up the fractionating column (see figure 1). the vapor condenses on glass spurs (known as trays or plates ) inside the column, and returns to the distilling flask, refluxing the rising distillate vapor.. Distillation system uses several methods to maximize the purity of the products and one of these methods is called refluxing. the vapor is coming of the top of the tower are condensed in a condenser and then collected in the receiver. part of the liquid from the receiver is sent to storage or other unit in the plant as tower overhead product..
