摘　　要：建立了脱单塔系统的费用模型,确定影响脱单塔设计优化的关键变量为废水进料温度、塔内件型式和丙烯腈脱除率,对一步法蒸发冷凝水脱单塔系统的操作与设备费用进行分析。以总成本最小为目标,完成三个关键变量与系统总成本的关联,以操作费用和设备成本最小确定关键变量的选择方案,并对工业设计进行指导。结果表明,当选择圆筒型散装填料作为塔内件时,系统的总费用比选择板式塔要低。将理论计算结果用于工业设计,优化设计点是若干设计工况中的最佳点。A cost model of the single tower is established,in which feed temperature of wastewater, column internal and acrylonitrile recovery are determined as key variables to analyze the operation and capital costs of acrylonitrile removal system for one-step condensate. To obtain the minimum total cost, the correlations between these three key variables and the total cost are analyzed. The operation and capital costs are minimized to choose the optimal case which could conduct industrial design. The results show that the total cost of the plant using random cylindrical packing column is lower than that using tray column. Applying the optimization results to industrial design, the optimized point is the best circumstance of several design conditions.
