✦ Synopsis

The effects of varying degrees of micromixing on overall conversion, average copolymer composition and copolymer composition distributions in a premixed feed-stirred tank reactor have been theoretically analyzed. The analysis is based on kinematical considerations from continuum mechanics and the Atiqullah-Nauman micromixing model. The calculated, macroscopic composition distributions widen with the increase in segregation number N~8. However, the overall conversion and average copolymer composition remain relatively unaffected. The study also shows how the micromixing parameter, that is, the striation thickness so, can be calculated from the measured-and model-predicted composition distributions, and N~g.
