OPTIMAL-DESIGN AND OPERATION OF BATCH REACTORS .1. THEORETICAL FRAMEWORK

In this work, we propose a framework for integrated design and operati on of single-stage batch or semibatch reactors. This includes systemat ic decoupling of optimization and design through conceptual decomposit ion of the reactor dynamics into two subsystems with distinct characte ristics. In this framework, notions of feasibility, flexibility, contr ollability, and safety of the design for batch processes are introduce d for the first time and some criteria for their assessment are presen ted. The proposed framework includes (a) mathematical modeling of the process dynamics, (b) dynamic optimization that involves simultaneous optimization of loading conditions and operating temperature and/or co ncentration profiles, (c) design of the heat exchange and/or feeding s ystem(s) and investigation of process operability (feasibility, flexib ility, controllability, and safety of the design), and (d) design of a control scheme for automatic startup and optimal operation of the rea ctor.
