摘　　要：进行DWC分离苯/甲苯/二甲苯3组分混合物实验:在相同操作条件下,与常规侧线采出精馏塔进行对比,并通过改变DWC的进料位置、侧线采出位置及隔板位置等条件,考察对分离效果的影响。实验结果表明,分隔壁精馏塔侧线采出产品纯度高出常规侧线采出塔28个百分点以上,达到96.4%。同时,侧线进料口位置、采出口位置及隔板位置等均对分离效果产生明显影响,在分离上述3组分芳烃混合物时,当进料位置取进料口2,采出位置取采出口2,隔板位于塔中部时,分离效果最佳。A dividing wall column was used to separate mixture of benzene/toluene/dimethyl benzene and compared with traditional side run-off tower in the same operational condition.Influences of feed position,side-draw position and dividing wall position on separation effect were investigated.The results indicated that side-draw product＇s purity of DWC was 28 percent higher than traditional side run-off tower,could reach 96.4%.Meanwhile,influences of feed position,side-draw position and dividing wall position on separation effect were obvious.The optimal separation condition was that when the feed position and sidedraw position all were position 2,and the dividing wall was in the middle of the DWC to separate above-mentioned arene mixture,the result of separation was optimal.
