While designs vary, a standard agitated pressure vessel reactor consists of several critical components:
Vessel Shell: The main body, typically a cylinder with domed ends (dished heads), a shape proven to withstand internal pressure most effectively.
Agitator/Impeller: The “spoon” that stirs the pot. This mechanical stirrer ensures reactants are perfectly mixed, maintains a uniform temperature, and suspends solids.
Heating/Cooling Jacket: A shell wrapped around the vessel through which thermal fluids (steam, water, or oil) circulate. This system adds or removes the intense heat generated or required by chemical reactions.
Baffles: Stationary plates mounted inside the vessel that break up the circular flow caused by the agitator, preventing vortex formation and ensuring chaotic, efficient mixing.
Head & Nozzles: The top or bottom assembly features various ports for introducing reactants, sampling products, and installing critical instrumentation.
The Safety Suite: The most non-negotiable part of the system.
Pressure Relief Valve (PRV): A reusable valve that automatically “pops” open at a pre-set pressure to safely vent excess gas and re-close.
Rupture Disc: A single-use, sacrificial membrane that bursts at a precise pressure, acting as a final, fail-safe barrier against over-pressurization.
Pressure Gauges & Temperature Probes: The eyes and ears of the operator, providing real-time data on the reaction’s status.
