| 摘 要： | 针对合成气一步法合成二甲醚的精馏精制过程,研究分离二甲醚-二氧化碳-甲醇-水混合物的顺序问题.根据精馏分离过程特点,将二甲醚混合物精馏精制分离过程分成多阶段的决策过程,建立相应的分离工艺方案动态规划模型.在模型求解过程中,提出年操作费用最小准则,并利用动态规划算法计算出不同阶段、不同决策下的目标函数最优解,得到最优的分离序列.结合研究体系的特点,将动态规划结果加以改进,给出二甲醚精馏精制最优分离方案.

| Abstract: | It is economical for practical investment and operating cost to study on the separation sequences for dimethylether-CO2-methanol-water separation.The dynamic programming model for the separation project is developed while the research system is separated into multistage decision process according to distillation separation features.The minimum annual cost of separation sequence is as the object function,and the optimum separation sequence is obtained through the dynamic programming algorithm.By modifying th... |
