The Aspen simulation for the organic amine-based CO2 capture process keeps giving errors; I don’t know how to fix it.

I created a new file, and the components, methods, chemical reactions, etc. used were all based on the data from the MEA CO2 absorption examples provided by the software. I set up a simple system for using MEA to absorb carbon dioxide from flue gas; however, once it was run, errors appeared – the process couldn’t converge after 200 iterations, and there was an imbalance in the materials involved. Complete beginners have no idea how to make modifications and are hoping very much to get help from experts.
