A Methodology for the Analysis and Design of Reaction-separation-recycle Systems

The study of the behaviour of Reaction-Separation processes with Recycle (RSR) becomes relevant for an integrated design and (plantwide) control at the early stages of the conceptual design, so that not only the recycle structure of the flowsheet can be established but also the operability of the system can be assessed. On the other hand, a computer-aided process design relies on the existence of model-based systems, giving the opportunity to develop a systematic model-based analysis that contributes to the formulation and solution for problems related to integrated process design. The objective of this paper is to present how the study of RSR systems can be made following a systematic approach in order to find the right set of information that leads to an integrated design as well as to provide enough information for the establishment of control policies.
