摘要
以水作为吸收剂,利用ASPEN PLUS软件对丙酮回收系统进行了优化分析,其结果为:吸收塔塔板数为10,吸收剂流量为2.30kmol/h,吸收剂温度为20℃;蒸馏塔理论板数为17,回流比为1.5,进料位置为第10块,再沸器热负荷为-32.21kW,冷凝负荷324.63kW,在保证丙酮纯度和收率的前提下,有效地降低了设备费用和操作费用,可为实际装置的运行提供一定指导。
Taking water as acetone absorbent,the optimization analysis of acetone recovery system was conducted with ASPEN PLUS.The results are as follows： the number of tower plates in absorption tower is 10,the absorbent flow and the absorbent temperature in absorption tower are 230 kmol/h and 20 ℃,respectively.In distillation tower,the number of theoretical plates is 17,the reflux ratio is 1.5,the feed stage is at 10th plate,and the heat duties are-33.85 kW（at the top） and 317.30 kW（at the bottom）.Equipment and operating costs were effectively reduced,providing the guidance for practical equipment operations with the satisfactory purity and yield of acetone.
