摘　　要：利用流程模拟软件Aspen Plus对丁辛醇装置中丁醛异构物分离塔进行了流程模拟,建立了与装置实际参数相吻合的理论模型。根据模型,以节能降耗为研究目标,采用灵敏度分析的方法,对丁醛异构物分离塔的进料位置和塔顶冷凝器的冷凝温度进行了调整。累计节约冷却水101.5t/h,低压蒸汽1.33t/h,降低了生产成本,提高了装置的盈利能力。Process simulation of the separation process of n-butanal and isobutylaldehyde was conducted by using Aspen Plus.The flow model was established with the actual parameters of the device.According to the model,taking the energy saving and consumption reduction as the research object,the feed position and the condensing temperature of the condenser at the top of the tower were adjusted by the method of sensitivity analysis.Saving cooling water consumption 101.5t/h and low pressure steam 1.33t/h,thus reduced production costs,improved the profitability of the device.
