How do the simulation results correspond to the distillation experiment data?
Thread Content
Hello, Sea Friends. Recently, I conducted distillation experiments as well as Aspen simulations on a certain raw material, and I have the following questions for which I hope you can help answer them: ① Some substances do not have CAS numbers, so structural formulas were used along with estimation methods for the simulations. The simulation results show a bottom temperature of 130°C, whereas the bottom temperature in the distillation experiment tower reached 155°C. How can I adjust the simulation file so that the bottom temperature matches the actual value? ②The experimental results regarding the distribution of various substances at the top and bottom of the tower do not match the simulation results; should the component distribution be adjusted by modifying the parameters for binary interactions? Due to limited resources that prevent the conduct of gas-liquid equilibrium experiments, my approach is to adjust the binary interaction parameters based on the results of distillation experiments. However, since there are multiple binary interaction parameters between each pair of components, is it necessary to rely on manual trial and error? Thank you all!
Why align? Simulation merely provides tools or methods to save time on experiments and trial and error. It is recommended to change the approach; in this case, simply conducting experimental operations will suffice.
