CO2 Absorption from flue gas HYSYS
CO2 Absorption from flue gas HYSYS
(OP)
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! :(

BRE people provides all the required technical assistance (if you post here I must suppose that Aspen is not helping)
For a real application (not a student work) technical assistance and support has a value.

RE: CO2 Absorption from flue gas HYSYS
the selection of partial or total condenser can depend from presence (or not) of incondensables (as for other separations),
it may seem that you have not experience with these simulations, if that is the case better to ask for specific technical assistance as suggested by xeng,

FYI, I'm actually working in and Oil & Gas Company but I don't have the expertise in this item. Thank you for your advice.
