Hello,

 

Could you please share typical HETP values of packing for amine contactor?

I have found some information about efficiency of trays but not for packing. I've monoethanolamine solution and sour gas with mainly of H2S content. The target is removal of H2S.

 

Kind regards,

Nikolay

HETP in absorbers depends on many factors, such as packing type, liquid viscosity, absorption factor, et cetera,

Different packings give different interfacial areas (m2/m3) and liquid viscosity depends on temperature, amine type and amine concentration.

 

20 - 30 years ago, when I was often involved in the design of HDS and HCU which usually included an amine absorber, I remember that we used HETP = 3 m (three meters) for DEA or MDEA over 2 inch random packing (2" Pall rings or IMTP50).

This is just to give you a rough idea. For different amine and different packing type & area one would need to adjust that HETP.

 

You best contact the vendor of your particular packing for a more exact HETP number based on present knowhow.
