加氢装置换热器泄漏失效的原因及对策研究

Failure Causes and Countermeasures Hydrogenation Unit Heat Exchanger Leak

换热器是一种常见的化工设备,其主要应用于化工厂,作为重要的化工设备,其主要的功能在于帮助热量从热流体中传递到冷流体中。分析加氢装置换热器的工作原理可知,作为加氢裂化装置中的重要组成,化工厂中加氢装置换热器长时间处在高温高压下,或者处在临氢等十分恶劣的环境下,设备的材料需要经受住高温和强腐蚀,同时加氢装置换热器还需具备综合的机械性能和回火的脆度。除此之外,加氢装置换热器内部的介质多属于易燃易爆物,一旦设备在运行中发生泄漏的情况,后果不堪设想,对企业造成巨大损失,因此分析加氢装置换热器泄漏失效的原因及对策具有现实意义。

The heat exchanger is a common chemical equipment,which is mainly used in chemical plants,as an important chemical equipment,and its main function is to help transfer heat from the hot fluid to the cold fluid.Analysis hydrogenation plant heat exchanger known works,as hydrocracker important component,chemical hydrogenation apparatus heat exchanger for a long time in high temperature and pressure,or in the presence of hydrogen and other very harsh environments materials,the equipment needs to withstand high temperatures and strong corrosion,while hydrogenation plant heat exchangers need to have the crispness of comprehensive mechanical properties and tempered.In addition,the hydrogenation unit inside the heat exchanger medium multiinfl ammable and explosive materials within the scope of the case leaked once the equipment is running,the consequences could be disastrous,causing huge losses to the enterprise,so the analysis Hydrogenation Heat Exchanger f AILURE reason is of practical signifi cance and countermeasures.
