摘　　要：针对重整变压吸附(PSA)装置系统压差异常升高问题,分析发现原料气中的氯离子和铵离子反应生成氯化铵,导致管线、吸附塔入口筛网及吸附剂孔隙堵塞,同时吸附剂中的硅胶发生破裂。通过实施优化吸附剂装填方案、对吸附塔进行水洗及加强原料杂质控制等措施,有效延缓了PSA装置压降的上升趋势,保障了装置的长周期平稳运行。To address the abnormal pressure differential increase in the reforming Pressure Swing Adsorption(PSA)unit,analysis revealed that chloride and ammonium ions in the feed gas reacted to form ammonium chloride,causing blockages in pipelines,inlet screens of adsorption vessels,and adsorbent pores,along with fragmentation of silica gel in the adsorbent.By optimizing adsorbent loading procedures,implementing water washing of adsorption towers,and enhancing feed impurity control,the measures effectively mitigated the PSA unit's pressure drop increase,ensuring long-term stable operation.
