A typical batch reactor consists of a storage tank with an agitator and integral heating/cooling system. These vessels may vary in size from less than 1 litre to more than 15,000 litres. They are usually fabricated in steel, stainless steel, glass-lined steel, glass or exotic alloy. Liquids and solids are usually charged via connections in the top cover of the reactor.
Aug 24, 2016 · The reactor temperature is controlled by pumping water through the outer jacket. The temperature is set using the temperature bath controls. The temperature bath incorporates an internal pump. The jacket cooling/heating water is fed into the jacket from the bottom glass nipple connector on the glass jacket, the water exits the jacket from the upper
When the flow of cooling liquid through the jacket decreases, some of the energy from the heat-producing reaction, rather than being carried away with the cooling liquid, accumulates in the vessel and drives the reactor temperature higher. The result is an increased conversion of reactant feed to product. As shown in the figure below (click for .
A variable tubular reactor is described which contains a plurality of parallel reaction tubes held between two tube plates in a cooling medium container. The reaction tubes are connected outside of the tube plates with 180° bends to form a tubular coil, whereby at least a part of the tube bends are connected to the respective tube ends by releasable flange connections.

Reactant B flow to the reactor is modulated by flow controller FIC-312. Inlet and outlet reactor temperatures are indicated by TI-311 and TIC-323 respectively. TIC-323 controls the outlet reactor temperature by modulating the cooling and heating flows to the reactor jacket, indicated by FI-304 and FI-305 respectively.
A jacket can be welded to the outer wall of most Parr pressure vessels to provide a means for heating or cooling the vessel with a hot or cold liquid or steam. This type of heating is ideal for users who want to duplicate plant operating conditions, using a jacketed reactor .
A loop reactor is a hybrid type of catalytic reactor that physically resembles a tubular reactor, but operates like a CSTR. The reaction mixture is circulated in a loop of tube, surrounded by a jacket for cooling or heating, and there is a continuous flow of starting material in and product out. PFR (plug flow reactor)
