【摘要】 通过对常压炉炉管及转油线腐蚀情况的分析,认为该炉发生转油线腐蚀泄漏的主要原因是原油含硫量升高、冲刷加剧、材质不适合以及设备老化等。针对腐蚀的成因采取了对整个转油线进行包盒子处理、材质升级、摸清活性硫在装置中的分布情况和腐蚀规律、开展高温部位定点测厚、避免高含硫原油直接进入装置等措施。更多还原

【Abstract】 By analyzing corrosion on the tube of atmospheric furnace and transfer line,leakage from transfer line of the furnace is mainly caused by highly sulfur contained in crude oil,serious erosion,inapposite material and equipment ageing.According to the reason of corrosion,some measures are taken,such as the transfer line is wholly packed,material is upgrated,the distribution and corrosion regulation of active sulfur in the unit is understood,the thickness of high temperature position is measured at fixed point,all of these are for the purpose to avoid crude oil with high sulfur entering into the unit directly.更多还原
