This chapter is organized to deal with a number of retrofit issues dedicated to batch plants. First, the typical features of batch plants are presented in Section 8.2. This is essential for the reader to understand the formulation of the batch design/retrofit problem in which they are intrinsically captured, as highlighted in Section 8.3. Section 8.4 is then devoted to 

Chemical Process Retrofitting and Revamping Techniques and Applications, First Edition. 

The production of high-value-added products (pharmaceutical active principles, agrochemicals, etc.) has stimulated investigations on batch processes for several decades. Generally, a batch plant can manufacture several products sharing standard equipment in a series of production campaigns, with the ability to adapt itself to variations of raw materials and to rapid market flucmations. A batch process involves discrete tasks embedded in an interconnected predefined sequence from raw materials to final products. The predefined sequence is commonly known as a recipe. The recipe consists of the amount of raw materials that are necessary to be involved in the individual tasks as well as their durations. It also includes the operating conditions of the tasks as well as additional constraints of the process (safety features for instance).
