Chemical Reactor Vessel ( Batch Reactor Vessel ) is the generic term for a type of vessel widely used in the process industries. This type are used for a variety of process operations such as solids dissolution, product mixing, chemical reactions, batch distillation, crystallization, liquid/liquid extraction and polymerization. In some cases, they are not referred to as reactors but have a name which reflects the role they perform (such as crystallizer, or bio reactor).
They are usually fabricated in PP - HDPE - FRP - PVC - CPVC - PVDF , MS FRP Lined , MS PP Lined , MS HDPE Lined , MS PVDF Lined , MS CPVC Lined . Vapors and gases also discharge through connections in the top. Liquids are usually discharged out of the bottom.
