โœฆ Synopsis

Ahatract-A

new mathematical model has been developed for the stirred tank reactor. The model assumes a circulating flow, created by the pumping action of the stirrer, and an isotropic homogeneous turbulence in the circulated fluid.

For a continuously operating stirred reactor expressions are derived for the conversion of a first-order reaction, the spread in residence times and the distribution function. It is shown that at high circulation/feed rate ratios and/or at high turbulent ditlusivities the model approaches the ideal mixer. Correlations are proposed for the circulation rate parameter and the turbulent diffusivity parameter.

The mixing process in a stirred batch reactor is evaluated and described as a function of time and location.

The expressions are useful for the correlation of some experimental results.

The purpose of this paper is to analyse transient and steady-state polycondensation in a continuous, stirred-tank reactor as an example of large, complex kinetic systems. The approach used is to effect a partial analytical solution of the exact rate equations supplemented by a numerical solution by
