摘要
本工作对低温精馏分离13 C同位素的稳态模拟与动态模拟进行了研究。使用商用流程模拟软件Asp-en Plus建立低温精馏过程的稳态模型,通过对比模拟数据与实验数据,验证物性参数和模型的可靠性。使用Aspen Dynamics建立低温精馏过程的动态模型,动态模拟结果与实验数据吻合良好。结果表明,可以使用Aspen Dynamics对碳同位素分离过程进行动态特性研究,并对精馏过程进行开车时间预测、控制方案分析、操作性分析和安全性分析等。
The steady-state and dynamic process simulation of the cryogenic rectification process of isotope C-13 was researched.The commercial process simulation software Aspen Plus was used to establish the steady-state model of the cryogenic rectification process.The reliability of the model was validated by the comparison of the simulation result and the experimental data.It showed that the technological process design of high quality C-13 can be conducted with software Aspen Plus.The dynamic process model was built with software Aspen Dynamics.The simulation results with the models were well supported by experimental ones.It showed that the dynamic characters of the separation process can be investigated with Aspen Dynamics.Then,the dynamic start-up time,control scheme analysis,operability analysis,and safety analysis etc.can be implemented with dynamic simulation.
