摘　　要：针对扬州石油化工厂常压催化热联合装置存在常压塔侧线组分分割不清、重叠较大等问题,选用一种新型LLC-Tray高效立体传质塔盘代替常规的条形塔盘;对比了塔盘改造前后装置的运行效果,并对改造后的装置进行了经济技术分析。Aiming at problems existing in the atmospheric catalytic combination units of Yangzhou Petrochemical Complex,such as ambiguous incision,large superposition of side-cut distilates in the atmospheric tower,new LLC-Tray stereomass-transfer tower plates were applied in the atmospheric tower to substitute conventional bar-shaped tower plates.Running effects of the modified units were compared,and economic results and technical analysis were made too.
