Amine loading value
Amine loading value
(OP)
Hi dears,
I am a new member in this forum.
I apologize for my English language.
I have a question about amine regeneration unit design.
What is the best value for lean and reach amine loading (mol H2S/mol MDEA) for amine regeneration unit (stripper column) design?
what is your idea about this parameter?
I thank all friends in advanced.

RE: Amine loading value
Lean AG loading = 0.01 mol/mol max
Rich AG loading = 0.40 mol/mol max
RE: Amine loading value
Lean solvent loadings for MDEA are in the range <0.005 mol/mol, while rich solvent loadings depend on the operating pressure of absorber (and corresponding acid gas partial pressure). One should never exceed the value of 70% of theoretical equilibrium at given conditions, in spite of the fact that rich amine loading sometimes can be even higher than 1. For pure MDEA at elevated pressures, these values can reach 0.5-0.6 mol/mol, with 0.5 mol/mol being recommended as the safety operating limits.

Usually the know-how company will advise the recommended loadings.
We are using DEA with lean 0.005 and rich 0.3 mol/mol.

RE: Amine loading value
So, thank you so much for your data.
Please let me know if, which design parameter shall been considered for determination of Amine Loading?

Then things like percent slip of CO2 desired...
