Distillation is the separation or partial separation of a liquid feed mixture into components or fractions by selective boiling (or evaporation) and condensation. Distillation is mainly characterized in two types, Continuous Distillation and Batch Distillation. Continuous distillation, a form of distillation, is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams. Whereas, batch distillation is, where the mixture is added to the unit at the start of the distillation, distillate fractions are taken out sequentially in time (one after another) during the distillation, and the remaining bottoms fraction is removed at the end.
Continuous Distillation is one of the most widely used separation technique in the Chemical Process Industry. The exhaustive scientific and practical knowledge of this process has been gained over the last few decades. Being an energy intensive process, the optimum operation of continuous distillation columns assumes considerable economic importance. Continuous distillation is used widely in the chemical process industries where large quantities of liquids have to be distilled. Such industries are the natural gas processing, petrochemical production, coal tar processing, liquor production, liquified air separation, hydrocarbon solvents production and similar industries, but it finds its widest application in petroleum refineries.
The advent of continuous processing in the chemical industries has brought with it a requirement for a much more stringent control of the process variables. In general, continuous processes are more sensitive to operating conditions than batch processes. In addition, because of their generally large size operations at other than optimum conditions, is costlier in plant returns, this further increases the requirement for close control.
