Jacket temperature control - SWEP

Earlier, the cooling and the heating fluids entered directly into the reactor jacket (no intermediate heat exchangers were used). This meant that the jacket had to be emptied of one fluid before the next could be let in. This was a very slow responding system. Furthermore, problems occurred because of mistakes being made when emptying and .

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.

Heat removal in the larger plant reactor was provided by an external jacket supplied with cooling water no less than 30°C. The alkene oxide feed rate was therefore restricted, due to the limited heat transfer by the jacket. A heat transfer model was developed using standard correlation for heat transfer in forced convection systems.
