The productivity of a bubble column reactor (BCR) critically depends upon gas-liquid mass transfer coefficient, k L a . The prediction of k L a as function of design and operating conditions is central to BCR scale up. A large number of researchers h

Stirred-tank reactors (STR), in which gas and liquid phases make intimate contact for mass transfer, are quite common in chemical processes. Mechanical agitation enhances the mixing performance and the oxygen transfer capability in bio-STR, but they

Nitroso compounds, such as 2-methyl-2-nitrosopropane, nitrosobenzene, and 4-nitrosophenol, were tested as volatile inhibitors for vapor-phase inhibition of acrylic acid polymerization during its reflux at 113 °C under reduced pressure. The experimen

Uniformly distributing slurry solids in “tall” (≥2:1 aspect ratio) process vessels is a significant challenge in the chemical industry. This work determined the performance of various multi-tier agitation systems in uniformly distributing a set

Ticklers are relatively small impellers operating near the bottom of slurry-containing stirred-tank reactors and storage vessels. They maintain solids suspension after the level of a draining slurry recedes below the main impeller(s). Typical pitched

Here we report on results obtained from large eddy simulations of flow inside a stirred tank performed using a spectral multidomain technique. The computations were driven by specifying the impeller-induced flow at the blade tip radius. Stereoscopic

In contrast to mixing in vertical tanks, jet mixing in long horizontal tanks is scarcely investigated in the literature. It is known that jet mixing in long horizontal tanks is more difficult when compared to short tanks, as more liquid volume must b

The stirred tank reactor is one of the most commonly used devices in industry for achieving mixing and reaction. We consider a combined experimental=computational approach for the simulation of oerent r–z planes phase locked at 0

This paper explores the use of phosphazenes as alternative lubricants for thin film hard disks. Contact start/slop (CSS), stiction and drag tests were performed on five disks lubricated with a typical cyclic phosphazene lubricant, X-1p, with a thickn
