Chlorsorb氯吸附技术在连续重整装置的工业应用

对比了传统碱洗和Chlorsorb氯吸附技术的工艺原理和技术特点。Chlorsorb技术在1.2 Mt/a连续重整装置的工业应用结果表明：随着温度的升高，氯吸附效果变差，在138～148 ℃时，氯吸附效果最佳；催化剂经氯吸附区后氯含量增加0.26百分点。分析了放空冷却器在138 ℃时的氯腐蚀机理及措施，探讨Chlorsorb技术在高温、高含水条件下对催化剂活性的影响，提出增加脱氯罐、选择高温脱氯剂等措施，以改善催化剂后期活性降低、氯吸附效果变差等问题。

COMMERCIAL APPLICATION OF CHLORSORB TECHNOLOGY IN CCR UNIT

The process principles and characteristics of the conventional caustic wash and chlorine adsorption(Chlorsorb) technology were compared briefly,and the application of Chlorsorb technology in a 1.2 Mt/a CCR unit was introduced.Operation results showed that with the increase of temperature,the efficiency of chlorine adsorption dropped,the optimum temperature for chlorine adsorption of the catalyst were in the range of 138—148 ℃;the chlorine content of catalyst after passing adsorption zone increased by 0.26 percentage point.The chlorine corrosion of vent gas cooler at 138 ℃ was analyzed and countermeasures were adopted.The effect of Chlorsorb technology under high temperature and high humid conditions on the activity of CCR catalyst was discussed and suggestions,such as adding a dechlorination tank and selecting high temperature chlorine adsorbent,to improve the operation during final stage were proposed.
