稳定同位素^(13)C分离二塔级联耦合优化设计与实验研究

Coupling Optimization Design and Experimental Study on Stable Isotope ^(13)C Separation of the Double-stage Cascade

采用均匀实验与Aspen Plus模拟耦合的计算方法优化13 C分离二塔级联工艺操作参数。经实验验证,实验值与耦合优化的模拟值吻合较好,相对误差为6.5%;在不增大能耗费用的同时,优化实验得到二塔釜的13 C丰度为14.1%,较二塔级联初始实验结果提高25%以上。结果表明,建立的耦合优化设计方法经实验验证可行,可为13 C产业化级联工艺设计提供理论参考,也可为其他传统精馏工业优化设计提供指导。

A coupling optimization design and experimental study method with uniform experimental and Aspen process simulation was established in this paper,which was used for stable isotope ^13C separation of the double-stage cascade.Based on the above method,the optimization operating parameters were received.The coupling optimization simulation value showed good agreement with the experimental dates,and the average relative error was only 6.5%.On the other hand,compared with the initial test result,the ^13C abundance of optimized experimental was 14.1%,and the actual growth rate of ^13C abundance was more than 25%.More importantly,The optimization experimental did not increase energy consumption.The method confirmed by the experiment could provide a solid foundation for the cascade process of ^13C industrialization,and it could also be applied to other traditional distillation industry.
