- Abstract
For the purpose of solving problems in water treatment system of the power station boiler from perspective of chemical process safety, a new method which uses the LOPA method in risk assessment for anticorrosion and scale inhibition properties of boiler system is proposed. First of all, a new annotation on the basic principle and calculation steps of LOPA is made in this paper. And then the consequence of the hazard scenario is determined by calculating the probability of accidents, such as putting poor quality water treated by the water treatment agents as initial event. Finally, specific implementable recommendations are provided by comparing the risk levels of independent protective layers system and ordinary system. The results show that the method that LOPA used in risk assessment for anticorrosion and scale inhibition properties of boiler is feasible, measures that recommended can reduce the risk; LOPA can further enrich HAZOP analysis results when introduced into boiler capacity link; layers of protection analysis, risk assessment together with humanistic management could be a new and effective security management model used by energy enterprise.
