Chemical Reactors: Semi-Batch Reactors

Chemical Reactors: Semi-Batch Reactors

A semi-continuous reactor is a reactor for a multiphase reaction in which one phase flows continuously through a vessel containing a batch of another phase. The operation is thus unsteady-state with respect to the batch phase, and may be steady-state or unsteady-state with respect to the flowing phase, as in a fixed-bed catalytic reactor or a fixed bed gas-solid reactor respectively.

Continuous reactor - Wikipedia

Continuous reactor - Wikipedia

Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.

Continuous Reactor - an overview | ScienceDirect Topics

Fluid flow in a continuous reactor is a very complex physical phenomenon that has direct impact on chemical reactions taking place inside the reactor, including both reaction rate and the extent of the reactions. Such an impact can be understood by examining the velocity distribution inside the reactor. It is well known that for fluid flow inside a tube, the radial distribution of velocity is .
