WebbIn an ideal plug flow reactor (PFR) the fluid particles leave in the same order they arrived, not mixing with those in front and behind. Therefore, the particles entering at time t will … WebbHistory. The concept of residence time originated in models of chemical reactors. The first such model was an axial dispersion model by Irving Langmuir in 1908. This received little attention for 45 years; other models were developed such as the plug flow reactor model and the continuous stirred-tank reactor, and the concept of a washout function …
WebbThe reaction residence time is determined by the pump flow rate and not the size or length of the reactor process channels, allowing the user to easily screen a range of residence times on demand. Mixing efficiency and plug flow performance is maintained by default, irrespective of flow rate. WebbPlug flow reactor residence time distributions A reasonable assumption for the fluidized-bed reactor is that the fluid is partially mixed, whereas the solid is fully mixed. If we …
WebbThe residence time distribution is consequently an impulse in this formulation of the ideal plug flow reactor (a small, narrow spike function). To estimate important reactor variables including the reactor’s size, the plug flow reactor model is used to forecast the behavior of chemical reactors with tubular designs.
