摘要
为实现高丰度^(13)C同位素的分离,本文基于Aspen Plus软件开展模拟计算,通过自定义组分补充了同位素分子的相关物性参数,建立了分离^(13)C同位素多级级联分离工艺模型并验证了其准确性。根据模拟计算的结果,确定了三塔级联的工艺路线,通过建立的工艺模型模拟了^(13)C同位素三塔级联过程的浓度分布规律,分析了原料进料量、加热功率、操作压强等单因素对塔底产品丰度的影响。最后考虑到多因素的交互作用,利用多元线性回归和规划求解的方法,得到了二塔塔底产品丰度值与原料进料量、一塔加热功率、二塔加热功率之间的关系式及最优解,模拟计算的结果可用于指导级联装置的设计和优化。
In order to realize the separation of high abundance ^(13)C isotope,this paper carries out simulation calculations based on Aspen Plus software,supplements the relevant physical parameters of the isotope molecules with custom components,establishes a multistage cascade separation process model for the separation of ^(13)C isotope and verifies its accuracy.Based on the results of the simulation calculations,the process route of the three-stage cascade was determined,and the concentration distribution law of the three-tower cascade process of ^(13)C isotopes was simulated by the established process model,and the influences of single factors such as raw material feed amount,heating power,and operating pressure on the abundance of the products at the bottom of the tower were analyzed.Finally,considering the interaction of multiple factors,the relationship equation and optimal solution between the abundance value of the product at the bottom of the two towers and the raw material feed amount,the heating power of the first tower,and the heating power of the second tower were obtained by using the methods of multiple linear regression and planning solution,the results of the simulations can be used to guide the design and optimization of cascade units.
