高温缓蚀剂在4.0Mt/a常减压装置的应用

APPLICATION OF HIGH TEMPERATURE CORROSION INHIBITOR ON 4.0 Mt/a ATMOSPHERIC AND VACUUM DISTILLATION UNIT

炼油企业因不断提高原料中高硫高酸原油的占比,在获得较高经济效益的同时,也承担了较高的风险。为降低高温部位设备的腐蚀速率,确保安全生产,在客观条件不具备材质升级的情况下,4. 0 Mt/a常减压装置通过加注高温缓蚀剂有效减缓了高温部位设备的腐蚀速率,确保了装置的安全生产。

Proportion of high sulfur and high acid crude oil in the oil refining enterprises was raised constantly.Higher economic profit was gained and higher risk was undertaken at the same time.In order to reduce corrosion rate of the equipment in the high temperature location and ensure safe production,under the actual condition that material could not be upgraded,the corrosion rate of the equipment in the high temperature location was efficiently slowed down by addition of high temperature corrosion inhibitor in 4..Mt/a atmospheric and vacuumdistillation unit.
