Most things can be improved, so chemical engineers and scientists optimize. While designing systems and products requires a deep understanding of inﬂuences that achieve desirable performance, the need for an efﬁcient and systematic decision-making approach drives the need for optimization strategies. In recent years there has been a growing recognition of the importance of considering control issues early in any chemical process. This interplay between process control in chemical engineering has become especially important for modern plants, which tend to have a larger degree of chemical material and energy integration and tighter performance specifications.
As a influence of global competition, rapidly changing economic conditions, and stringent environ‐mental and safety regulations, process control in chemical engineering has become increasingly important in the chemical process industries. It is also clear that the scope and importance of process control technology will continue to expand. Consequently, chemical engineers required to master this issue in order to be capable to operate and design modern plants.
