Hi All,
I'm struggling to find a reference reporting a figure related to the CO2 capture capacity for MEA (moles of CO2/mole of MEA).
Could you please recommend any?
Thanks,
Antonio
U can find it anywhere, just google it. Rate is 0.5 in theory, in order to remove 1mol of co2 u will need 2 moles of MEA. But in real life it is litter lower, around 0,45 - 0,48
Check papers by Gary Rochelle - Utexas
The problem raised by Vuk (effective absorption capactity lower than the theoretical of 0.5 carbamate / MEA molecule) is primarily related to the degradation of some MEA molecules (thermal and chemical reasons).
Check these refs for the degradation mechanisms

And that one for the purification techniques http://www.sciencedirect.com/science/article/pii/S1750583612001624

Joao F Gomes,
We are also actively research in the are. The litrature you mentioned seems good to read, would you mind sending them too.
Thanks
