连续重整装置氯的危害及对策

Chlorine corrosion and prevention in continous catalytic reforming unit

通过更换气相脱氯剂将重整氢气中的氯含量降低至0.1μg/g以下,有效防止了氯化铵对重整反应系统,稳定塔系统以及加氢装置的危害。通过投用液相脱氯罐,将汽油相中的氯含量降低至0.7μg/g,液化气顶部的干气中氯含量下降至0.5μg/g以下,有效防止了氯对金属的腐蚀,保证了装置的安全平稳运行。

By replacing the hydrogen chlorine-removal agent,the chlorine content in the CCR hydrogen is decreased to less than 0. 1 μg / g. It is effective in preventing ammonia salt blocking in CCR reaction system,Hydro-treat unit and stabilizer. By applying liquid phase de-chlorination drum,the chlorine content in gasoline is decreased to 0. 7 μg / g,while the dry gas in the top of LPG drum is decreased to less than 0. 5 μg / g. It is the important measures to prevent corrosion of the metal.
