✦ Synopsis

A mathematical model is suggested for expressing the residence time distribution in a multistage system with backmixing between stages and non-ideal mixing in each stage. This non-ideal behaviour is taken into account by considering each stage to be composed of a series of vessels with backmixing between the vessels. The residence time distribution curves are obtained by numerical solution of a set of mass balance differential equations. It is shown how the ordinate and abscissa of the maximum point of the residence time distribution curve can be used to evaluate the parameters of experimental curves. An analytical expression is derived for fractional conversion calculation for a homogeneous reactor based on the above model and the relative importance of individual model parameters is indicated.
