Models are defined for various mixing conditions, in continuous flow systems. Differential equations are derived which take into account aneffective volume of mixing, possible short-circuiting, hold-up time of the system, partial displacement or piston flow. The values of the different factors contained in the integrated equations can be determined experimentally by the particular response of a given system to a sudden change in composition of the feed. A correlation of the effective volume of mixing and the agitator r.p.m. is presented. A design procedure is suggested for tank flow reactors when partial mixing occurs.
