汽油无碱脱硫醇装置运行问题分析及改进

对汽油脱硫醇装置脱硫醇率低、精制汽油产品质量不稳定的原因进行了分析。通过采取更换床层活性炭、优化工艺流程、改进活化荆加注方式和床层再生工艺、调整活化荆加注比例、固定床定期脱水等措施，保持了床层的高活性，提高了脱硫醇能力，装置精制汽油馏出口合格率由65％左右提高到90％以上．固定床完好运行周期由最长4个月延长到7个月以上。

Analysis and Improvement of the Operation of Alkali Free Gasoline Sweetening Device

Low sweetening efficiency of gasoline sweetening device and unsteadiness quality of refined gasoline products are analyzed. High activity of the bed is maintained by replacing the bed activated carbon, optimizing the technological process, improving the activator filling method and bed regeneration process, adjusting the filling percentage of the activator and fixed bed periodic dehydration, etc. The sweetening ability is also improved in this way. Consequentially, the acceptance rate of the refined gasoline distillate of the device is increased from 65% to 90%, and the fully functioning period of the fixed bed increased from 4 months the most to 7 months the least.
