Event-based reduced-attention predictive control for nonlinear uncertain systems

Event-based control is an alternative to traditional control where new measurements are sampled only if critical events occur. This not only allows to reduce the control effort but it satisfies nowadays application requirements, such for example reduction ...

Model predictive control and dynamic operability studies in a stirred tank: rapid temperature cycling for crystallization

Gene Bunin

A stirred-tank reactor was built with the objective of rapid and accurate temperature control in the reaction vessel. A first-principles heat transfer model was developed for the jacketed batch system, with the jacket inlet temperature used to control the ...

Function computation over linear channels

Christina Fragouli, Lorenzo Keller, Nikhil Karamchandani

We consider multiple non-colocated sources commu- nicating over a network to a common sink. We assume that the network operation is fixed, and its end result is to convey a fixed linear deterministic transformation of the source data to the sink. This line ...

Compact reactor for continuous multi-phase reactions

Martin Grasemann

The objective of this thesis is the development of a compact reactor for continuous three-phase reactions in single-pass configurations. The design is based on a bubble column reactor staged with layers of catalytic material. To make the reactor suitable f ...

N2O Decomposition over Fe-ZSM-5 Studied by Transient Techniques

Albert Renken, Lioubov Kiwi, Bryan Bromley, Petra Prechtl

N2O decomposition to gaseous N-2 and O-2 catalyzed by a commercial Fe-ZSM-5 has been studied by different transient techniques: (i) via the transient response methods at ambient pressure, (ii) via the temporal analysis of products (TAP) reactor under vacuu ...

A thermodynamic solution model for calcium carbonate: Towards an understanding of multi-equilibria precipitation pathways

Paul Bowen, Jacques Lemaître, Marcel Donnet

Thermodynamic solubility calculations are normally only related to thermodynamic equilibria in solution. In this paper, we extend the use of such solubility calculations to help elucidate possible precipitation reaction pathways during the entire reaction. ...

Fast temperature cycling of the catalytic CO oxidation using microstructure reactors

Martin Luther

The possibility to increase the performance (productivity or selectivity) of a chemical reactor by using periodic variations of reaction parameters (e.g. reactant concentration or temperature) has been theoretically envisaged since the beginning of the 70t ...

Optimization of reaction calorimetry for monitoring chemical reactions in supercritical fluids

Charalampos Mantelis

The PhD thesis deals with the optimization of the reaction calorimetry technique to monitor chemical reactions in supercritical fluids. The aim is to develop this thermal analysis technique to monitor the heat released by a chemical reaction in a high pres ...

Forced periodic temperature cycling of chemical reactions in microstructure devices

Albert Renken, Lioubov Kiwi, Martin Luther

In this publication, several stainless steel microstructure reactors specially designed to obtain rapid and periodic temperature changes are presented. Different microstructure reactor designs have been manufactured and tested for their thermal behaviour a ...
