Batch Cooling: Speed Up Cycle Time | Chemical Processing

Jul 10, 2014 · FIX THE JACKET Increase the surface area for cooling by piping up cooling water to the reactor jacket. When you need to go from heating to cooling mode on the reactor, you will want to drain the condensate out of the jacket. So, install a drain valve and vent valve on the jacket.

Batch reactor - Wikipedia

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.
