BACKGROUND
The aim of this study was to identify the hazards, evaluate their risk factors and determine the measure for promotion of the process and reduction of accidents in the chemical unit of the power station.
METHODS
In this case and qualitative study, HAZOP technique was used to recognize the hazards and problems of operations on the chemical section at power station. Totally, 126 deviations were documented with various causes and consequences.
RESULTS
Ranking and evaluation of identified risks indicate that the majority of deviations were categorized as "acceptable" and less than half of that were "unacceptable". The highest calculated risk level (1B) related to both the interruption of acid entry to the discharge pumps and an increased density of the acid. About 27% of the deviations had the lowest risk level (4B).
CONCLUSION
The identification of hazards by HAZOP indicates that it could, systemically, assess and criticize the process of consumption or production of acid and alkali in the chemical unit of power plant.
背景
本研究的目的是识别危险，评估其风险因素，并确定促进发电站化学单元流程及减少事故的措施。
方法
在本案例及定性研究中，采用危险与可操作性分析（HAZOP）技术来识别发电站化学部分操作中的危险和问题。总共记录了126个具有各种原因和后果的偏差。
结果
对识别出的风险进行排序和评估表明，大多数偏差被归类为“可接受”，不到一半为“不可接受”。计算得出的最高风险水平（1B）与酸进入卸料泵的中断以及酸密度增加有关。约27%的偏差具有最低风险水平（4B）。
结论
通过HAZOP识别危险表明，它可以系统地评估和批评发电厂化学单元中酸和碱的消耗或生产过程。
