**Abstract**

In this chapter, the esterification reaction of methyl acetate with methanol and acetic acid is proposed by the new column configuration that is a reactive divided wall distillation column (RDWC). The heat integration of the proposed column configuration is studied and found that heat integration techniques are efficient to save energy up to 14.23% in comparison to the conventional reactive divided wall distillation column.
