✦ Synopsis

Micromixing effects on consecutive-competing second order reactions in an ideally macromixed CSTR are investigated by the use of the Two Environment Model of Ng and Rippin for mixed feed, and the model of Spielman and Levenspiel for unmixed feed.

General plots are obtained for various values of reaction and mixing parameters. Yield of the desired product is found to show a maximum at intermediate states of micromixing for unmixed feed condition. For mixed feed condition, micromixing effects are found to be very small.

The effect of micromixing on steady-state multiplicity is not displayed by the universal reaction model (URM) since this URM has considered any chemical species having the same mixing time constant. The modified universal reaction model (MURM) is derived for overcoming the above limitation. The desi
