Strong multiphysics coupling towards simulation of edible oil hydrogenation in monolith type reactor

Pierre Albrand1, Carine Julcour1, Anne-Marie Billet1
1Laboratoire de Génie Chimique, Toulouse INP, Toulouse, France

Different phenomena control the performance and even selectivity in multiphase reactors. Moreover, a two way coupling between the physics could be expected when physical and/or chemical properties depend on the conversion rate. Hence, this presentation aims to show a methodology to model ... Mehr lesen

Finite Element Model for Microwave Heating Used in Chemical Recycling of Plastic Waste Material

A. Frisa-Rubio1, C. González-Niño1, N.R. García-Polanco1, T. García-Armingol1
1Fundacion CIRCE, Zaragoza, Spain

Introduction Over the last years, there has been an increasing interest in plastic recycling as an alternative to reduce fossil fuel dependency. In this light, chemical recycling has been presented as a promising strategy to maximise the recycling rate, although this technology presents ... Mehr lesen

Simulation of Mixing and Polymerization in 3D-Printed Tubular Reactors including SMX-Mixing Elements

1University of Hamburg, Hamburg, Germany

The progress within the field of additive manufacturing has eased the fabrication of new reactor geometries significantly. It is possible to design and print a reactor of tailored shape and size at comparatively low costs and short time. Printing and testing all sensible reactor designs ... Mehr lesen

Simulation of Methanol and Urea Production from Catalytic Conversion of Steel Mill Gases

Dr.-Ing. Stefan Schlüter1
1Fraunhofer UMSICHT, Oberhausen, Germany

The time-dependent operation of methanol, ammonia, and urea production units embedded in a steel mill technical environment is analyzed with dynamic simulation models. From different process concepts and gas availability scenarios a set of simulation cases is defined with blast furnace ... Mehr lesen

Computational Fluid Dynamic (CFD) Modelling of Methanol Steam Reforming in Microreactors
