Chapter 1. Introduction parametric MPC (mp-MPC) controller design for the PSA purity control. To start with, the concept of multi-parametric model predictive control (mp-MPC) extending from the MPC optimization framework is explained. The main steps involved in the functioning of both controller modes are also discussed. Next, the mp-MPC controller design procedure following a step by step framework is explained. Finally, the results obtained from the comparison of closed loop performance of mp-MPC with the standard PID controllers are demonstrated. • In Chapter 5 a simultaneous optimization and control strategy for PSA op- eration under uncertainty is presented. First, a detailed literature overview of historical as well as the current state-of-the-art optimization based method- ologies for simultaneous design and control of process systems under un- certainty is presented. Furthermore, detailed comparisons are also drawn among the key PSA optimization methodologies. Next, details of the key challenges involved in design, operation and control of PSA system are pro- vided and incorporated into a simultaneous design and control optimiza- tion framework. Furthermore, detailed comparisons are also drawn with the conventional sequential design and control approach and explicit/multi- parametric MPC as the controller mode. • Chapter 6 provides design heuristics for the integration of PSA-membrane system for improving hydrogen overall recovery as compared to stand-alone PSA system. Here, details of stand alone membrane and PSA configurations are discussed first, which eventually assist in preparing a good base case for the hybrid. Finally, life cycle analysis of hybrid process is also performed to evaluate its environmental impact. • In Chapter 7 important conclusions and potential future directions from 26
