Opaque Multiphase Reactors: Experimentation, Modeling and Troubleshooting

Opaque Multiphase Reactors: Experimentation, Modeling and Troubleshooting — Multiphase reactors are widely used in petroleum, chemical, petrochemical, pharmaceutical and metallurgical industries as well as in materials processing and pollution abatement. Most reactors of interest in industrial practice (slurry bubble columns, gas-solid risers and fluidized beds, ebullated beds and stirred tanks...

Computational Flow Modeling of Multiphase Mechanically Agitated Reactors

Mixing and dispersion of solids and gases in liquids in mechanically agitated reactors is involved in about 80% of the operations in the chemical industries, including processes ranging from leaching and complete dissolution of reagents to suspension of catalysts and reaction products, such as precipitates and crystals (Smith, 1990). This is one of the most widely used unit operations because o...

Process Intensification in Multiphase Reactors

Introduction Applications of multiphase technology are prevalent in petroleum refining, synthesis gas conversion to fuels and chemicals, bulk commodity chemicals, specialty chemicals, conversion of undesired by-products to recyclable products, manufacture of polymers, biotechnology and pollution abatement. In these processes the reactor performance is crucial: it determines the number and size ...

Fiber-Optical Sensors: Basics and Applications in Multiphase Reactors

This work presents a brief introduction on the basics of fiber-optical sensors and an overview focused on the applications to measurements in multiphase reactors. The most commonly principle utilized is laser back scattering, which is also the foundation for almost all current probes used in multiphase reactors. The fiber-optical probe techniques in two-phase reactors are more developed than th...
