I´m having problems with my simulation in HYSYS. I'm simulating CO2 absorption from flue gas with MEA 30%w, my problem is the stripping section. I only specifying in the stripper the reflux ratio =0.3, temperature in the reboiler=120 °C, pressures around 180 psi, and stages=20. I found in different sources that typically reflux ratio is 0.1 to 0.3 but with this ratio I have high temperatures in the condenser and the stream that suppose to be CO2, it's 80% mol water. Another doubt is that in some articles, I read that the condenser is partial and I'm specifying reflux total. The diameter in my tower is the default value, I don't know if this is a problem too.
Please help me! :(
