In a Complete Mixed Reactor, the defining idea is that the contents are thoroughly stirred so everything is uniform inside the vessel at any moment. Because of this complete mixing, the concentration and temperature are the same throughout the reactor, and the material leaving the reactor has the same composition as the mixture inside. It also operates with continuous flow, with reactants continually entering and products continually leaving, which distinguishes it from a batch process that has no in/out flow. The other descriptions point to different reactor types: no flow in/out describes a batch process; fluid moving as plugs describes a Plug Flow Reactor where mixing is minimal along the flow path; and flow through media describes flow through a packed bed or porous medium, not a well-mixed tank.
