摘　　要：文章对胜利炼油厂蜡油加氢装置的临氢高压空冷器出口管线及重油加氢装置低压酸性气体脱硫系统胺液再生塔顶空冷器出口管线的腐蚀进行了分析 ,指出H2 S含量、介质流速、温度及材质是影响腐蚀的主要因素 ,并提出控制介质流速在 0 .4～ 0 .6 1m/s、合理选材。s: The corrosion of the outlet piping of high-pressure air cooler of the hydrotreating unit and the outlet piping of the overhead air cooler of amine regenerator of the low-pressure acid gas desulfurizer of the heavy oil hydroprocessing unit was analyzed. It was concluded that H2S content, fluid velocity, temperature and construction of material were the major factors for the corrosion. The corrosion could be prevented by controlling the flow velocity within 0.4~0.61 m/s, selecting proper materials, injecting corrosion inhibitors and strengthening corrosion monitoring.
