The hmltmg residence hme dlstrlbuhon (RTD) of contmuous recycle systems as the recycle ratlo approaches mlimty IS consldered It IS shown that the RTD converges to the exponential dtstrlbutlon whenever the system does not consist of a "dead volume" at the hnut Thus hmltmg behavior IS independent of t
Equations are presented for the residence time distribution in recycle systems with crossmixing between the forward and recycle streams. The use of the method of moments to obtain the system parameters, the crossflow and recycle rates, is described and the implications of the limits of the model are
The residence-time density function for a recycle system usually tends to exponential form, with mean equal to the ratio of the volume to the volumetric flow-rate, when the recycle rate is increased at constant throughput. Two conditions each suffidient to guarantee this behaviour are: (i) that the
