Advantages of Batch Distillation

The main advantages of batch distillation over a continuous distillation lie in the use of a single column as opposed to multiple columns and its flexible operation. 

The continuous distillation columns are designed to operate for longer hours (typically 8000 hrs a year) and therefore each column (or a series of columns in case of multicomponent mixture) is dedicated to the separation of a specific mixture. 

However, a single mixture (binary or multicomponent) can be separated into several products (single separation duty) and multiple mixtures (binary or multicomponent) can be processed, each producing a number of products multiple separation duties) using only one CBD column (Logsdon et al., 1990 Mujtaba and Macchietto, 1996 Sharif et al., 1998). 

Finally, in pharmaceutical and food industries product tracking is very important in the face of strict quality control and batch wise production provides the batch identity (Low, 2003).
