Question

Q/ Why the efficiency of batch distillation process should be decrease as we increase the power input?

Answer 1

Ans : Batch distillation refers to the use of distillation in batches, meaning that a mixture is distilled to separate it into its component fractions before the distillation still is again charged with more mixture and the process is repeated. This is in contrast with continuous distillation where the feedstock is added and the distillate drawn off without interruption. Batch distillation has always been an important part of the production of seasonal, or low capacity and high-purity chemicals. It is a very frequent separation process in the pharmaceutical industry.

so the processes which is carried out are heat sensitive if the power input is increased the desired separation may not be achieved leading to decreased efficency of the process
