2020-8-17 · A batch glass reactor is a vessel used for various processes such as batch distillation, crystallization, product mixing, and chemical reactions. Some industries refer to them as bioreactor because of the roles they play.. A batch reactor is a combination of several tanks, a storage tank with an agitator and a cooling system. These vessels vary in sizes depending on the industry.

Semi-Batch or Semi-Continuous Reactor - Process Operations

2006-4-23 · 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.
