长岭炼油厂蒸馏装置腐蚀状况

Corrosion of Crude Distillation Unit in Changling Refinery

文章介绍了长岭炼油厂原油性质的变化趋势及馏分油中酸值及硫含量的变化规律 ,对蒸馏装置的设备腐蚀状况、腐蚀规律进行了总结。同时指出 :对于低温轻油和高温重油等腐蚀严重部位可选用 16MnR +316L复合钢板、18-

s: The variation trend of crude oil properties and variation laws of acid value and sulfur content in distillates in Changling Refinery were described. The equipment corrosion and corrosion patterns in the distillation unit were summarized. It was concluded that the selection of 16MnR+316L composite steel plate, 18-8 stainless steel and A3+316L composite plate for could reduce the corrosion in corrosive low-temperature light oil and high-temperature heavy oil service.
