采用精密精馏从碳五馏分中分离1-戊烯的流程模拟

Process simulation of rigorous distillation for separating 1-pentene from mix C5 hydrocarbon

利用Aspen模拟软件,为获得1-戊烯产品对轻组分及重组分分离进行优化设计,形成建议的1-戊烯生产工艺路线。得到最佳的分离组合为脱重-脱轻组合,其中脱重塔理论板数145块,回流比23.0;脱轻塔理论板数130块,回流比73.1;1-戊烯产品收率80%是合理的。

Using Aspen plus software, the process for separation of 1-pentene from mix C5 hydrocarbon is proposed. Based on the simulation results ,the optimal separation process is determined as the coupe of heavy and light component removal columns. The theoretical plate numbers of heavy and light component removal columns are 145 and 130, respectively. Their corresponding reflux ratio is 23.0 and 73.1 mol/mol. The acceptable yield of 1-pentene （80% , mass fraction） is also achieved.
