Question

how to calculate distillation time and how can we reduce the time cycle of distillation​

Answer 1

Distillation is the process of separating components of a mixture based on different boiling points. Examples of uses of distillation include purification of alcohol, desalination, crude oil refining, and making liquefied gases from air.Fractional distillation always endeavors to achieve high purity of the fractions collected. You can improve the purity of the fraction by increasing the surface area of the fractionation column. Remove the fractionation column from the distillation unit and pack the internal space with steel wool.The operating time, top, is the actual period during which distillation occurs, so it must be equal to the total amount of distillate collected divided by the distillate flow rate. We usually operate at a fraction of the maximum flow rate, such as D = 0.75 Dmax. The operating time, top, can be estimated from Eqs
