ABSTRACT
The transient nature of batch distillation allows for conguring the column in a number of dierent ways, a few examples of which were shown in Chapter 1. The column at the right in Figure 6.1 is a conventional batch distillation column with a reboiler at the bottom and a condenser at the top, which essentially performs the rectifying operation. In contrast to a conventional batch distillation column, the inverted column (Figure 6.1, left) has its storage vessel at the top and the products leave the column at the bottom. Thus mixtures with a small amount of the light component can be separated by removing the heavy component as the bottom product. These two columns are comparable to the rectifying and stripping parts of a continuous distillation column but with additional exibility.
