Mechanical aeration polymeric

In this section, we first evaluate the design of conventional nonaerated and aerated stirred slurry reactors. Since the design of mechanically agitated gas-liquid reactors has already been discussed in Section II, here the main emphasis is placed on the effects of solids on the design parameters. We subsequently illustrate some special-purpose slurry reactors used in the chemical and petrochemical industries. Novel slurry reactors used in biological or polymeric industries are discussed in Sections VI and VII, respectively. 

In order to elucidate the detailed mechanism of the radiation-induced polymerization, both direct observation of the intermediates and analysis of the final products should be carried out, as was done in a later paper28. The authors found that although the spectrum of the transient is unaffected by the presence of oxygen, the final product depends on the presence or absence of oxygen. De-aerated benzonitrile solution of VC... 

Gas-to-liquid mass transfer is a transport phenomenon that involves the transfer of a component (or multiple components) between gas and liquid phases. Gas-liquid contactors, such as gas-liquid absorption/ stripping columns, gas-liquid-solid fluidized beds, airlift reactors, gas bubble reactors, and trickle-bed reactors (TBRs) are frequently encountered in chemical industry. Gas-to-liquid mass transfer is also applied in environmental control systems, e.g., aeration in wastewater treatment where oxygen is transferred from air to water, trickle-bed filters, and scrubbers for the removal of volatile organic compounds. In addition, gas-to-liquid mass transfer is an important factor in gas-liquid emulsion polymerization, and the rate of polymerization could, thus, be enhanced significantly by mechanical agitation.
