Improve Batch Reactor temperature control

utilities supplying the jacket, e.g., a steam-header pressure control loop. In the reactor loop, linearity means getting symmetrical set-point responses from the jacket. If the cooling and heating responses of the jacket are asymmetrical (as in Figure 5 or for steam versus cold water), consider a gain scheduling controller to compensate.

Avoid corrosion in glass lined reactors

Aug 05, 2015 · heat transfer fluids used in the jacket space are relatively mild (especially in comparison to the contents inside the reactor itself), they will generally attack the jacket as well as the reactor exterior long before the glass-lined interior becomes damaged. The most common form of jacket fouling is iron oxide corrosion.

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.

Differences in the heating method of glass reactors and .

The heating of the double glazing reactor is carried out by heating/cooling the material in the kettle through the heating/cooling medium in the intermediate layer. However, when heating a double-glass reactor, it is necessary to equip a high-temperature circulating oil bath to connect the kettle body of the double-layered kettle.
