How to obtain the parameters for simulating the reaction kinetics of methanol production from syngas using Aspen

Generally, based on experience, the tear flow paths that need to be torn first are identified first; for the modules for which calculations are possible, an approximate initial value is assigned if no exact initial value is available (or a range of values is given). Multiple calculations are performed (to optimize and assess sensitivity) until convergence is achieved, and the results are analyzed to obtain a more accurate initial value. Nevertheless, experiments are still required to further confirm the initial parameter values as well as the results of other theoretical calculations. If the degree of alignment between the two is very high, it can be determined to be correct ； If the difference is significant, it is possible to use the initial values from the experiment for calculation, and then compare the results. Theory and practice complement each other.
