Recent advances in optimization-based simultaneous process and control design
TL;DR: This work first discusses recent advances towards the integration of process design, process control and process operability from the open literature and then focuses on techniques towards this endeavor that were developed within the group at Imperial College.
Journal ArticleDOI
Modeling and optimization of polygeneration energy systems
TL;DR: In this paper, the authors present a model for the investment planning of a poly-generation energy system and a case study addressing a system for production of methanol and electricity in China during the period from 2010 to 2035.
Journal ArticleDOI
Process intensification: New understanding and systematic approach
TL;DR: In this paper, the authors present new definitions for process intensification identifying two main categories called unit intensification and plant intensification, and propose general mathematical programming formulations for the different categories of intensification through a disjunctive formulation to consider the use of existing units or to include additional units.
Journal ArticleDOI
Hierarchical multiscale model-based design of experiments, catalysts, and reactors for fuel processing
TL;DR: A hierarchical multiscale simulation framework is outlined and experimental data injection into this framework is discussed and the use of such detailed and reduced kinetic models in reactor optimization as an example toward more conventional process design is illustrated.
Journal ArticleDOI
An overview of process intensification methods
TL;DR: This paper summarizes and compares the approaches that have been suggested for retrofit using PI and criteria to evaluate PI options, and reviews the evolution of phenomena-based representations, a central theme in the synthesis for PI.

On the optimization of differential-algebraic process systems
J. E. Cuthrell,Lorenz T. Biegler +1 more
TL;DR: In this article, a method based on finite-element collocation is presented, which converts differential equations to algebraic residual equations with unknown coefficients, and then a nonlinear program is formulated, with residuals incorporated as equality constraints and coefficients as decision variables.
