Amine solution issue
Thread Content
Recent device analysis results show that the MDEA concentration in the rich amine solution is higher than that in the lean solution. Why? Has anyone encountered this situation? The normal amine-poor solution concentration should be higher than that of the amine-rich solution!
It is possible for the rich amine solution to have some of its water evaporated, resulting in an increased concentration
Isn’t the regeneration of rich amine solution just lean amine solution?
Isn’t the regenerated rich amine solution just the lean amine solution? The concentration of the lean amine solution is still high!
The rich amine solution contains H2S gas; during steam regeneration, this H2S gas is released, and at the same time the water in the solution also evaporates, resulting in an increase in the concentration of the amine solution.
I know this, but others ask why the concentration of the active components in the rich amine solution is higher than that in the lean amine solution!
