Is the main reason for your amine to be loaded up with H2S Co2 the low temperature or is it that the percentage of amine is higher then normal 50 50?

Answer 1

To me both reason can incresed acid gas loading in lean amine.

1.When lean amine temperature is low then then amine absorb more quantity of H2S,CO2 which result high acid gas loading in lean amine.

2.When amine solution concentration is hiegher than 50/50 then slow absorption of CO2 but H2S absorption incresed which result high acis gas loading in lean amine.

Note: Lean amne temperature is the main thing to increase acid gas loading.

My take is that if your amine titration is higher than 50%, and are having trouble with loadings, then you are probably running out of regeneration (still/reboiler). It is critical to maintain a good overhead temperature and reboiler temperature so that the amine can be regenerated. Proper titration and lean amine temps tie back into this...

Answer 2

The main reason for loading up with H2S and CO2 is typically the higher than normal amine concentration rather than the lower temperature. A higher amine concentration allows for better absorption of acidic gases like H2S and CO2, which is necessary for effective gas sweetening processes.
