Introduction to batch chemical processes

By definition, a batch process is any process that is a consequence of discrete tasks that follow a predefined sequence from raw materials to final products. The prescribed sequence is known as a recipe. These processes are mostly suited to production of low volume, high value-added products, where equipment sharing is common. In most instances, equipment sharing is a result of similar recipes. The following sections are aimed at giving a brief account on the very key areas of research covered in this book. These pertain to scheduling in batch plants, which deals solely with handling of time, followed by energy and water minimization. The role of time is fundamental in the operation of batch facilities, since most batch unit operations are time-constrained. Only the essential elements of batch plants are captured with references, where necessary, to further sources of information for the benefit of the reader.
