In continuous distillation, the source materials, vapors, and distillate are kept at a constant composition by carefully replenishing the source material and removing fractions from both vapor and liquid in the system. This results in a better control of the separation process.
There are four main points of difference by which we can differentiate between liquids and gases at the most basic level; shape, volume, hardness, and the capacity to flow. Liquids. The molecules of liquids have a moderate force of attraction; the force between molecules is less than solids and more than gases. This results in the movement of molecules more easily and freely within liquids. The molecular movement results in liquids having a definite and fixed volume.
