<p>Batch chemical processes, so often employed in the pharmaceutical and agrochemical fields, differ significantly from standard continuous operations in the emphasis upon time as a critical factor in their synthesis and design.</p> <p>With this inclusive guide to batch chemical processes, the author introduces the reader to key aspects in mathematical modeling of batch processes and presents techniques to overcome the computational complexity in order to yield models that are solvable in near real-time. This book demonstrates how batch processes can be analyzed, synthesized, and designed optimally using proven mathematical formulations. The text effectively demonstrates how water and energy aspects can be incorporated within the scheduling framework that seeks to capture the essence of time. It presents real-life case studies where mathematical modeling of batch plants has been successfully applied.</p>

Batch chemical processes are always ideal in the manufacture of small-volume, high-value-added products, as traditionally encountered in pharmaceutical,agrochemical and food and beverage industries. The main distinción between these processes and their continuous counterparts pertains to the handling of time. Continuous operations can attain steady state, wherein time is completely overridden, whereas batch operations are never at steady state. This simply implies that time can never be ignored in the analysis of batch processes. Consequently, the synthesis, design and optimization of these operations should embed time as a critical dimension.
