通过分析确定了二氧五环和水液相活度系数计算模型为NRTL,采用Aspen Plus软件数据回归功能得到了二者的二元交互作用参数。在此基础上，建立了二氧五环合成与浓缩工序的计算机模型，运用灵敏分析功能优化了精馏塔的进料位置和回流比。由回归参数计算的汽液平衡数据与实验数据误差较小，说明回归的参数可信度较高，同时计算机模拟结果与实际工艺数据吻合良好，表明该模型较好的反映了实际的生产过程。优化结果显示，精馏塔适宜进料位置为第22块塔板、适宜回流比为0.9。
通過分析確定瞭二氧五環和水液相活度繫數計算模型為NRTL,採用Aspen Plus軟件數據迴歸功能得到瞭二者的二元交互作用參數。在此基礎上，建立瞭二氧五環閤成與濃縮工序的計算機模型，運用靈敏分析功能優化瞭精餾塔的進料位置和迴流比。由迴歸參數計算的汽液平衡數據與實驗數據誤差較小，說明迴歸的參數可信度較高，同時計算機模擬結果與實際工藝數據吻閤良好，錶明該模型較好的反映瞭實際的生產過程。優化結果顯示，精餾塔適宜進料位置為第22塊塔闆、適宜迴流比為0.9。

Chosen the NRTL equation as the liquid activity coefficient computation model for 1, 3-Dioxolane and water, the binary interaction parameters for these mixtures were regressed using aspen plus. On that basis, a simulation model was built for the 1, 3-Dioxolane synthesis and concentration process and the optimization for the distillation process was did with the sensitivity analysis function. Simulation results were identical with experimental data from literatures and industrial site, indicating that the factory production processes were well reflected by this simulation model. Through this model, some distillation operation parameters were optimized including feed stage and reflux ratio.
