| 某炼油厂第一、三常压蒸馏装置分别炼制胜利混合原油和中东进口原油,设备腐蚀比较严重。在第一、三常压 蒸馏装置塔顶换热器入口设置电阻探针对腐蚀速度进行了测量,对原油的硫含量、盐含量、脱盐后的盐含量、酸值、 塔顶产品槽中铁离子含量等与腐蚀有关的参数进行T监测，采用灰色系统理论对影响腐蚀速度的因素进行了分析， 求出了绝对关联度、相对关联度和综合关联度,并对关联计算结果和设备腐蚀的原因进行了分析。研究表明,对第 一和第三常压蒸馏装置塔顶设备腐蚀影响最大的因素是含酸量和脱盐后的含盐量。 |

| Abstract: |
| Shengli and Middle-east crude oil were refined in the first and third atmospheric distillation unit separately and the corrosion is serious. The corrosion rate on the top of the atmospheric distillation tower was measured using electric resistance probe. The sulfur value, salt value, salt value after desalt, acid value in crude oil and iron ion value in product container were monitored every one or two month. Grey correlation analysis was carried on by grey system theory. The absolute, relative and synthetic degree of incidence were calculated. The computational solution and the reason of corrosion were analyzed. The main factor related to the corrosion is acid value on the first atmospheric distillation unit, but the main factor is salt value after desalt in crudes for the third atmospheric distillation unit. |
