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 stirred-tank reactor - Wikipedia

The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering.A CSTR often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output.

Flow chemistry - Wikipedia

Continuous reactors are typically tube like and manufactured from non-reactive materials such as stainless steel, glass and polymers. Mixing methods include diffusion alone (if the diameter of the reactor is small e.g. <1 mm, such as in microreactors) and static mixers.Continuous flow reactors allow good control over reaction conditions including heat transfer, time and mixing.
