I want to use kinetic forms of reactions in aspen plus to simulate MSW gasification. I have already siumulated equilibrium form but the results were not close to experimental work. I would be so grateful if someone send me a step by step procedure to follow or some samples and files to help me. Many thanks.
Hello Shahin,
In "Solid Fuels Combustion and Gasification" Chapter 8, you can find a lot of information about chemical reactions in gasification systems (kinetics are included). In my opinion the easiest way is via a calculator block. So you can write a FORTRAN subroutine for the reactions rates calculations and declare it as export variable to a reactor model with kinetic (CSRT). A similar approach was used in Biogas Process Simulation Using Aspen Plus (available online). There you will find a subroutine for reaction rates calculation using Calculator Blocks. I hope it could help you.
Regards,
Junior
