A continuous flow model is developed which describes flow through a vessel in which the fluid undergoes axial dispersed plug flow and some of the flid is held back in a deadwater zone. The first three moments of the concentration‐time curve are related to the three parameters of the model, and an equation is presented to predict the outlet concentration from the vessel as a function of time for an impulse input. The model is used to analyze experimental gas‐phase residence‐time distribution (RTD) data collected from a small rotary calciner operated at room temperature. These data are well represented by the model.
