Reactor Design & Optimization of Heating & Cooling systems

While stirred reactor design as above function as batch reactor or even as continuous stirred tank reactors (CSTR), tubular reactors are generally used for reactions in continuous mode. Circulation of heating or cooling medium through the jacket or coil in the reactor design helps in supplying or removing the heat from the reaction mixture.

Batch reactor - Wikipedia

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.

Apr 07, 2020 · # 3 Batch Reactor Cooling Jackets. There are various cooling jacket types used for batch glass reactors.The main purpose of these cooling jackets is for regulating the temperature of the reactors.The cooling jackets are made up of the exterior layer of a reactor.

AGITATED VESSEL HEAT TRANSFER - Thermopedia

Heat transfer in agitated vessels can be carried out either through an external jacket on the vessel or by internal coils.Where a jacket or coils cannot provide the surface area required, a recirculation loop with an external heat exchanger may be used.

Jacketed Reactor Heating & Cooling - Sigma Thermal

Jacketed Reactor Heating & Cooling. In reactors, heating and cooling jackets are used to remove heat from exothermic reactions or provide the needed heat required to produce the desired endothermic reactions. Steam jackets that operate at high pressures can pose safety issues, especially when hazardous chemicals are being used within the reactor.

How to Make Transitions Between Cooling and Heating Smooth .

Insight: The throttling of a heat exchanger bypass flow instead of the cooling and heating flow makes the secondary jacket temperature control faster by eliminating the exchanger thermal lag. Use a PID with external reset feedback and directional moves suppression to help eliminate unnecessary crossings of the split range point and oscillations .
