摘　　要：以天津渤化永利化工股份有限公司#2丁辛醇装置中小板间距的丁醇异构物塔进料负荷提升为研究目标,结合实际生产装置调试结果,采用Aspen及KG-TOWER软件对丁醇异构物塔进行流程模拟及水力学计算,并根据研究结果采用VG固阀和弧形溢流堰对丁醇异构物塔进行优化改造,使丁醇异构物塔的进料负荷提高了20%上。本研究对提升丁辛醇装置中丁醇异构物塔的进料负荷具有重要的指导意义,为小板间距精馏塔的设计及优化提供了工程依据和研究基础。This study aims to improve feed loading capacity of a butanol isomer column in #2 butyl octanolunit of Tianjin Bohua Yongli Chemical Industry Co., Ltd. Following practical process adjustment, Aspen andKG-TOWER software were used to simulate the process and calculate related hydraulics, respectively.VG-fixed valves and arc-overflow weir were employed to optimize the inner structure of the butanol isomercolumn, and the feed loading capacity is increased by over 20%. This study is useful in improving feed loadingcapacity of butanol isomer columns in butyl octanol units, and provides guidance for the design andoptimization of distillation columns with small tray spacing.
