Overview

This presentation explores two different, difficult problems: heat exchanger design incorporating pinch analysis, and worst-case uncertainty analysis for batch reactors. Surprisingly, both of these problems can be addressed with a single underlying philosophy, in which a complicated process model is broken down into simple pieces that are then treated separately. For heat exchanger design, this approach entails applying a new variant of automatic differentiation to provide enough insight to handle the Second Law of thermodynamics in a robust pinch analysis. For batch reactors, a second variant of automatic differentiation describes how uncertainty in the process model emerges in the dynamic state, which can then be harnessed by optimization methods. Ongoing projects are also discussed.
