摘要
以乙醇、丙醇及丁醇为例,对分隔壁精馏塔用于三元混合物分离的操作特性及节能效果进行了模拟分析与研究。确定了分隔壁精馏塔的优化操作条件,即回流比为10、中间出料位置为第16块理论板、进入分隔壁进料侧的汽液相流量分别为30 kmol/h和80 kmol/h,分隔壁的上下部连接位置分别为第10块板和第23块板。结果表明:与常规精馏流程相比,采用分隔壁精馏塔可节能30.49%上。
With the separation of ethanol, propanol and butanol as an example, the operational performance and the energy saving effects of the divided wall distillation column were simulated and analyzed. The optimum operation condition was ascertained. The reflux ratio was 10 the middle outlet position was the 16th theoretical plate the vapor flow and liquid flow to the divided wall feed side were 80 kmol/h and 30 kmol/h, respectively. The upper and lower location of divided wall was the 10th and 23th theoretical plate, respectively. The result showed that applying the divided wall distillation column, the rate of energy saving is about 30% compared with the conventional distillation process according to the separation requirements.
