Exothermic chemical reactions are frequently dangerous because of the potential for a runaway reaction. cooling coils are provided in batch reactors to remove energy of reaction. in the event of a cooling water failure, the reactor temperature rises, resulting in a higher reaction rate and higher energy generation. the result is a runaway reaction. during a runaway reaction, the temperature can rise quickly, resulting in dangerous pressure within the reactor and a possible explosion. loss of cooling can be detected by measuring the temperature within the reactor and sounding an alarm. frequently, by the time the alarms sounds, it is too late. a) design a better instrumentation and alarm configuration to detect loss of cooling more directly (5 marks) b) construct a hazop study on this new design unit to improve the safety of the process. use cooling coil as study notes (process parameter: flow and temperature)
