Minimize Breakdowns and Maintenance Costs

The following areas should be addressed in order to nunimize the breakdowns and maintenance costs (which maximizes the run time)  

Refractory lining failure Acid piping and cooler leakages Corrosion of demister pads/failure of candle demisters Heat exchanger tube leakages Loss of catalyst activity 

Waste heat boiler, economiser, and superheater tube leaks Breakdowns of the air blower and its drive system
