“…This is particularly important for process synthesis where numerous design candidates exist and the identification of the most desirable one is always computationally expensive. The DP models introduced in this paper, together with those for heat exchanger networks (Yang et al, 1996;Yan et al, 2001), mass exchanger networks (Yang et al, 1999;Yan and Huang, 2002), and distillation column networks (Lou and Huang, 2002;Yang et al, 2000), are valuable for synthesizing highly controllable process systems. For heat-integrated reactors, stability is a very important issue, as addressed by Chen and Yu (2003) and Luyben (1998).…”

In process operation, reactor systems always experience various disturbances from the surrounding separation and=or energy recovery systems. If the design of a reactor system does not ensure adequate structural disturbance rejectability, the system may be less controllable or uncontrollable in operation. To facilitate the synthesis of a cost-effective, highly controllable reaction system for which a large number of design alternatives may exist, it is highly desirable to have a simple tool that can quickly assess disturbance propagation during flowchart development. In this article, a set of first-principles-based, yet simplified, structural disturbance propagation models is introduced for quickly quantifying SDP throughout a reaction system and then identifying design bottlenecks during conceptual design. The efficacy of the modeling is demonstrated by solving two practical example problems.

“…Wang and Lee (2002) explore nonlinear PI control for binary high-purity heat-integrated columns with light split/reverse conÿguration. Yang et al (2000) use simpliÿed model derived from state space equation to evaluate disturbance propagation for double-e ect column under feed-split conÿguration. Interaction between design and control for heat-integrated and/or thermally coupled distillation systems are studied by Rix and Gelbe (2000) and Bildea and Dimian (1999) using dynamic RGA as a controllability measure.…”

In the last three decades the importance of resolve a robust, rigorous and operable heat exchanger networks (HEN) is boosted due to the change in the concepts of effective cost of a HEN several methodologies are applied to solve the operability aspects of a HEN including flexibility and controllability of a HEN in this work a systematic approach is introduced to solve the controllability issue for HENs. The work framework consist of two major steps where in the first step a disturbance propagation model for a HEN is constructed adopting Yang et.al disturbance model[1][2][3]. The second step is to install a bypass to reject the disturbance then pair the manipulated and controlled variables in a HEN using NS-RGA (None Square Relative Gain Array) and SVD (Singular Value decomposition), by adopting controllability index developed by Westphalen et al.[4]to measure the HEN controllability and finally a cost tradeoff between the bypass installation and utility installation to control the same disturbance is evaluated to check for the more cost effective method to eliminate and reject the disturbance in hand.
