Dynamic Optimization and Non-linear Model Predictive Control to Achieve Targeted Particle Morphologies.

Chem Ing Tech 2019 Mar 21;91(3):323-335. Epub 2018 Dec 21.

University of Cambridge Department of Chemical Engineering and Biotechnology Philippa Fawcett Drive CB3 0AS Cambridge United Kingdom.

An event-driven approach based on dynamic optimization and nonlinear model predictive control (NMPC) is investigated together with inline Raman spectroscopy for process monitoring and control. The benefits and challenges in polymerization and morphology monitoring are presented, and an overview of the used mechanistic models and the details of the dynamic optimization and NMPC approach to achieve the relevant process objectives are provided. Finally, the implementation of the approach is discussed, and results from experiments in lab and pilot-plant reactors are presented. Read More

Impact of Catalyst Geometry on Diffusion and Selective Catalytic Reduction Kinetics under Elevated Pressures.

Chem Ing Tech 2018 Jun 26;90(6):795-802. Epub 2018 Apr 26.

Paul Scherrer Institut (PSI) Bioenergy and Catalysis Laboratory 5232 Villigen Switzerland.

In marine diesel engine applications, selective catalytic reduction (SCR) upstream of the turbocharger may become the preferred technology when dealing with high sulfur fuels and low exhaust gas temperatures. The target nitrogen oxide reductions in combination with minimum ammonia slip and reduced gas diffusion rates under elevated pressures require understanding of the impact of catalyst geometry on the SCR kinetics. The extent, trends, and sources for this observation are elucidated in this work by systematic testing of catalysts with equal geometry and/or intrinsic activity. Read More

Scale-Up of Innovative Honeycomb Reactors for Power-to-Gas Applications - The Project Store&Go.

Chem Ing Tech 2018 May 14;90(5):696-702. Epub 2018 Apr 14.

Karlsruher Institute of Technology Engler-Bunte-Institut Department of Fuel Technology Engler-Bunte-Ring 1 76131 Karlsruhe Germany.

The German "Energiewende" is heavily based on electric power and, therefore, requests solutions to serve non-electric energy uses and to store electric energy in large scale. Synthetic natural gas (SNG) produced with hydrogen from water electrolysis and with CO from mainly renewable sources is one approach. For the catalytic SNG production efficient removal and utilization of the reaction heat is the main issue. Read More
