摘　　要：在间歇精馏釜内具气液分布器,并增设持液收集器,使在精馏末期的填料层持液不与釜内已提纯的纯组分相混合,减少塔顶产品损失,可省时又节能。实践证明该技术在化学工业中很有推广应用价值。A liquid collector was added to an intermittent type of rectifying column to prevent the reefing material from intermiting with the stuff raw material near the end of the process. This technical can reduce the product loss, lessen the product time and save energy. The new technique is proven to be practical and have big potential for extending application in the chemical industry.
