【摘要】：獨山子石化公司5×10~4 t/a硫磺回收裝置自2009年開工以來,先后遇到汽提塔塔頂空冷器至回流罐管線彎頭腐蝕泄漏、空冷管束偏流發(fā)生凍凝泄漏、液硫夾套管內漏、急冷水線和酸性水線泄漏腐蝕、尾氣爐熄火、酸氣帶烴等一系列影響正常生產的問題。針對每一項問題做出了應對,并制定了防范措施。通過對各類問題發(fā)生的機理及對裝置造成的影響進行分析,確定了腐蝕泄漏問題是影響硫磺回收裝置長周期運行的最主要因素,防止設備和管線的非正常腐蝕是保證裝置長周期運行重要措施。
[Abstract]:Since the construction of the 5 脳 10 t / a sulfur recovery unit in Dushanzi Petrochemical Company in 2009, it has encountered corrosion leakage at the elbow of the top air cooler at the top of the stripping tower to the reflux tank pipeline, freezing condensation leakage of the air cooling tube bundle bias flow, and leakage inside the liquid sulfur jacket pipe. A series of problems affecting normal production such as leakage corrosion of chilled water line and acid water line tail gas furnace flameout acid gas zone hydrocarbon and so on. In response to each of the problems, and the development of preventive measures. Through the analysis of the mechanism of various kinds of problems and the influence on the unit, it is determined that the corrosion leakage is the most important factor affecting the long period operation of the sulfur recovery unit. Preventing abnormal corrosion of equipment and pipeline is an important measure to ensure long period operation of the device.
