Continuously operated stirred tank reactor has been design on the
assumption of perfect mixing to achieve 90% conversion of the first on
reaction. Subsequent flow patterns study (flow visualization and RTE
measurements) indicate that: (i) 65% of the volume is well mixed, (ii
20%, of the volume locally exhibits plug flow (iii) 15% volume is
inactive and 25% of the feed bypass the reactor. The conversion to be
expected from this reactor is to be estimated.
