摘要
某石化企业的硫回收装置存在易燃易爆性气体和毒性气体,为了提高安全风险控制水平,研究过程分析了硫回收工艺的危险性,介绍了反应气体的潜在风险及反应过程的腐蚀性,开展重大危险源等级评价;运用HAZOP分析法开展安全风险评价,根据评价结果制定相应的安全对策。结果显示,该装置的主要风险点为反应酸性气体夹带液态甲醇、设备轻度腐蚀、风量与酸性气体积分数不佳,针对以上问题提出了应对措施,包括增加缓冲罐、控制酸性气分液罐内部温度等。
The sulfur recovery unit of a petrochemical enterprise contains flammable and explosive gases as well as toxic gases.In order to improve the level of safety risk control,the research process analyzed the hazards of the sulfur recovery process,introduced the potential risks of reaction gases and the corrosiveness of the reaction process,and conducted a major hazard level evaluation.Conduct safety risk assessment using HAZOP analysis method and develop corresponding safety measures based on the evaluation results.The results show that the main risk points of the device are the presence of liquid methanol in the reaction acidic gas,mild corrosion of the equipment,and poor ratio of acidic gas to air volume.Corresponding measures have been proposed to address these issues,including adding buffer tanks and controlling the internal temperature of the acidic gas separation tank.
