Dear all,
I'm designing the Amine Contactor for removal of Acid Gases (CO2 & H2S) from the sour gas using MDEA and/or MDEA based solvents. In this regard I need simplified design procedure especially for:
1) Establishment of Amine circulation rate: the steps involved to determine the required circulation rate based on the Rich Amine solution Equilibrium and Design Loadings.
2) from the Literature, I understood that the operating rich loading will be 70 to 80% of Equilibrium Rich Loading. But I'm unable to fix/find Equilibrium Rich Amine Loadings.
Thanks in advance.
Regards,
Ravi

For gas scrubbing applications, equilibrium loading is strongly dependant on system operating pressure. Vapour-liquid equilibrium data is the basis for selecting the maximum loading and is the most important piece of data required to design any amine plant. These data account for the pressure and temperature of the specific application.

For more information, there is very good article published in PTQ, winter 2001/2, "Understanding Gas Treating Fundamentals", by James L. Jenkins and Randy Haws, CCR Technologies Inc. The article is available for direct download at: http://www.reclaim.c...undamentals.pdf
