The dependence on non-renewable resources, particularly fossil fuels, has awaken a
growing interest in research of sustainable alternative energy sources, such as bioethanol …

Several ionic liquids (ILs) were tested for their suitability to synthesize the aramid polymer
poly-p-phenylene terephthalamide (PPTA) in an attempt to diminish the dependence on the …

Mixing is perhaps one of the oldest and the commonest unit operation encountered in the
chemical, biochemical, polymer, food, agriculture, ceramic, paper, pharmaceutical and allied …

1-Octyl-3-methylimidazolium chloride ([C8MIM][Cl]) shows the greatest potential to replace N-
methylpyrrolidone/CaCl2 as solvent for the synthesis of poly (p-phenylene terephthalamide) …

In the present study, a CFD characterization of the flow generated by curved-blade impellers
in a cylindrical unbaffled vessel was carried out. The tank diameter was 300 mm, with a flat …

The current synthetic procedures for polyaramids mainly involve the use of amide solvents
such as N-methylpyrrolidone and N, N-dimethylacetamide. However, these solvents are …

An industrial-scale stereo-selective enzymatic oxidation process for the conversion of
pyrmetazole to esomeprazole was developed and optimized. Slurry-to-slurry stages are …

Mixing performance is critical as it may influence the quality of the mixture and operation
cost. In a viscous fluid application, the torque required to sustain the high viscosity is very …

Fluid mixing in stirred vessels is widely encountered in a number of industries. In this work,
different experimental techniques and the CFD modelling approach are used to measure the …

Objectives: kL a mass transfer coefficient was predicted using CFD (computational fluid
dynamics) for analyzing non-newtonian effects on gas liquid mass transfer in a 10 L …
