[270a] - Multidimensional Population Balance Modeling of Barium Sulfate Precipitation in Microemulsions

Investigation of Barium Sulfate Precipitation and Prevention Using Different Scale Inhibitors under Reservoir Conditions

In this work, scaling tendency and amount of precipitation of barium sulfate (BaSO4) were determined; the process is depending on temperature, pressure and mixing ratio of injection and formation of waters. Results showed that BaSO4 precipitation is largely dependent on mixing ratio. Temperature and pressure had no influence on BaSO4 precipitation. Different sca...

Nanoparticles of Barium Ferrite Synthesised Using a Water-in-Oil Microemulsion

The application of barium f&:e (BaFelZO19; BaF) in the magnetic media industry requires materials with strict control of homogeneity, morphology and magnetic properties resulting from their preparation and pretreatment. Here the use of water-in-oil microemulsions for the synthesis of nanoparticles of BaF is considered. Two microen~ulsions (containmg an aqueous phase, cetyltrimethylammonium brom...

Modeling of Catalyst Effect on the Reduction Rate Enhancement of Barium Sulfate by Methane and Developing Two Environmentally Friendly Processes

Population Balance Modelling of Zirconia Nanoparticles in Supercritical Water Hydrothermal Synthesis

Like any other precipitation process, in supercritical water hydrothermal synthesis (SWHS), the need to improve product quality and minimize production cost requires understanding and optimization of Particle Size Distribution (PSD). In this work, using Population Balance Equation (PBE) containing nucleation and growth terms, the reactive precipitation of zirconia nanoparticles prepared by ...

Precipitation of Barium Sulphate Nanoparticles in Microemulsion: Experiments and Modelling Fällung von Bariumsulfat Nanopartikeln in Mikroemulsionen: Experimente und Modellierung

Today, the scenario of a well-controlled large-scale production of nanoparticles is a very important aspect in nanotechnology. The present work aims at the investigation of different engineering aspects on the production of nanoparticles using microemulsions, which lead to possible process control. Prior to the precipitation process, this study explains that the phase behaviour of the ternary a...
