Issues related to simulating reactors for methanol utilization kinetics
Thread Content
1. I used Comsol to simulate the reactor for methanol synthesis. There are three reactions involved in methanol production: CO + 2H2 → CH3OH, CO2 + 3H2 → CH2OH + H2O, and CO2 + H2 → CO + H2O. How many of these reactions should be used at the beginning?2. During the simulation, whether two or three of these reactions are chosen, how should the units of the fugacity coefficients and the reaction equilibrium constants for each substance be determined? 3. During the simulation, a convergence issue is always indicated – how should this be resolved? I hope the experts can give some advice
Those who do this kind of work should be graduate students at school. The answers to your first two questions can be found in professional books; look up information on the design of methanol reactors. It is still very difficult to complete this task; knowledge of programming is required for dynamics, thermodynamics, the calculation of material properties, reactor design, as well as the implementation of process calculations. It is very difficult to do well; if it’s just for graduation, it can still be accomplished using some simplified models.
