对二甲苯吸附分离装置吸附剂水含量控制分析

摘要

In this paper, the water balance in para-xylene separation unit is discussed. The effect of water in adsorbent on the stability and selective adsorption performance of the adsorbent is analyzed, finally, measures for keeping the optimal water content of adsorbent are put forward, such as proper controlling the amount of water injection, monitoring the water content in feed and tracing water balance daily, to prolong the service life of adsorbent and ensure a safety running of the unit under optimum conditions.%讨论对二甲苯吸附分离装置的水平衡,分析水对对二甲苯吸附剂稳定性和选择性吸附性能的影响,提出保持吸附剂最佳水含量的措施:注水量控制、进料水含量控制和水平衡控制等,以保证吸附剂的运行安全,优化装置运行,延长吸附剂使用寿命.
