利用Aspen Plus结合工厂的实际设备和工艺参数以及生产数据建立了电石法氯乙烯精馏工艺的模拟流程,分别对低沸塔和高沸塔的进料位置、回流比等主要操作参数进行了灵敏度分析和优化计算,获得了一致的最佳工艺参数。低沸塔进料位置为4块板,回流比为6;高沸塔进料位置为21块板,回流比为0.3。
Using Aspen Plus combined with the actual plant and process parameters and production data to establish a calcium carbide process for the distillation of vinyl chloride process, respectively, the low boiling point and high boiling point of the feed position, the reflux ratio and other major operating parameters of the sensitivity Analyze and optimize the calculation, get the best of the best process parameters. Low boiling tower feed location for the four plates, the reflux ratio of 6; high boiling tower feed position of 21 plates, the reflux ratio of 0.3.
