CFD modelling of liquid–liquid multiphase microstructured reactor: Slug flow generation

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid

Microreactor technology, an important method of process intensification, offers numerous potential benefits for the process industries. Fluid–fluid reactions with mass transfer limitations have already been advantageously carried out in small-scale geometr ...

Structured catalytic wall microreactor for efficient performance of exothermic reactions

Lioubov Kiwi, Bryan Bromley, Marina Ruta, Turan Eslanloo Pereira

A novel microreactor with structured catalytic wall (SCWMR) has been developed for highly exothermic, gas/solid reactions and tested for the selective acetylene hydrogenation. The reactor design is similar to the so-called "slit microreactor". The structur ...

A novel compact reactor for three-phase hydrogenations

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid, Martin Grasemann

A novel reactor based on a bubble column staged by structured catalytic layers with integrated cross flow micro-heat-exchangers (HEX) was designed and tested in the solvent free hydrogenation of 2-methyl-3-butyn-2-ol (MBY) aiming on process intensification ...

UV absorption of coherent and nano-porous titanium oxide films obtained by PECVD

Nasibeh Pouransari

Polymeric materials suffer from chain degradation due to the absorption of ultraviolet (UV) light. Nevertheless, many polymers show excellent optical transmission properties in the visible range and are suitable replacements for glass. Coating of polymers ...

Powder formation in SiH[sub 4]–H[sub 2] discharge in large area capacitively coupled reactors: A study of the combined effect of interelectrode distance and pressure

Christoph Hollenstein, Benjamin Strahm

One of the main challenges for silicon thin film deposition for solar cell applications is to achieve high rate deposition in order to reduce the manufacturing costs. However, when silane and hydrogen are used as precursor gas in parallel plate plasma-enha ...

Cross-section modelling effects on pressurised water reactor main steam line break analyses

Rakesh Chawla, Hakim Ferroukhi, Omar Zerkak

Because of the strong asymmetric overcooling effects occurring during a PWR main steam line break (MSLB) event, an accurate analysis of this transient requires the use of 3-D kinetics methods. An assessment has been made of the relative performance of the ...

Validation of Monte Carlo predictions of LWR-PROTEUS safety parameters using an improved whole-reactor model

Rakesh Chawla, Fabian Jatuff, Michaël Plaschy

The recent experimental programme conducted in the PROTEUS research reactor at the Paul Scherrer Institute (PSI) has concerned detailed investigations of advanced light water reactor (LWR) fuels. More than fifteen different configurations of the multi-zone ...

N-removal optimization by various aeration strategies

Simon Taillard

In order to improve the purification capacity of an aerobic granular sludge, two aeration strategies were designed and tested. The goal was to optimize the nitrogen removal performances via various oxygen patterns in the aeration phase of the reactor cycle ...

Alternative configurations for the QUADRISO fuel design concept

Manuel Alexandre Pouchon

This letter extends the work performed at Argonne National Laboratory on the QUADRISO fuel particles concept for High Temperature Reactors. Different configurations of the QUADRISO fuel particles concept are proposed and examined. The concept of QUADRISO f ...

Non-intrusive plasma diagnostics for the deposition of large area thin film silicon

Christoph Hollenstein, Alan Howling, Benjamin Strahm

Plasma diagnostics for large area, industrial RF parallel-plate reactors can be useful for process optimization and monitoring, provided that their implementation is practical and non-intrusive. For instance, Fourier transform infrared (FTIR) absorption sp ...
