Project on uses of exothermic reactions
WebMar 11, 2024 · Exothermic reactors are harder to control because safety is dependent on heat removal. There are two common control architectures for an exothermic CSTR based on the temperature of the coolant. The first method uses the outlet temperature of the coolant as the manipulated variable, while the second method uses the inlet temperature … WebIn exothermic reactions the temperature goes up, in endothermic reactions the temperature goes down. This is a useful class experiment to introduce energy changes in chemical …
