In the CP-flow type, the gas is fed to the distributing channel and travels radially from the outer screen to the center pipe. In the CF-flow configuration the gas is fed to the center pipe and travels radially from the center pipe to the outer screen. Therefore, four flow configurations are possible for a radial flow reactor.Plug Flow Reactor Static Mixer - stamixco-usa, all type radical flow reactor internalsPlug Flow & Radial Mixing A tubular reactor is a fundamentally simple continuous reactor where there are no moving parts other than pumps that deliver the reactants. In a typical slow chemical reaction system where long residence times are required, the fluids passing through a tubular reactor are in the laminar flow regime even when the materials are low viscosity water-like fluids.

Plug Flow Reactor Static Mixer - stamixco-usa, all type radical flow reactor internals

Plug Flow: In addition to excellent radial mixing, continuous reactors require plug flow conditions. Plug flow conditions means that all the material processed through the reactor must have the same residence time so that the chemicals exiting the reactor have witnessed the same reaction conditions of reactive species contact-time aging-temperature history.Ammonia Converter Baskets S-200 | Reactor Internals , all type radical flow reactor internalsThe Topsoe S-200 ammonia synthesis converter is a two-bed radial flow converter with indirect cooling between the catalyst beds. Since the introduction of the S-200 converter type in 1976, it has been used in more ammonia plants than any other converter design, COMSOL Multiphysics Simulation of Flow in a Radial Radial velocities across the catalyst bed are much lower, while the axial velocity in the inner annulus increases from zero to a quite high value. The high velocity region near the exit is caused by the constriction of the axial flow due to radial flow from the bed. Figure 4.
