Dehydration Column with gas feed not saturated with water

Dehydration Column with gas feed not saturated with water

(OP)

Hi

I am calculating the required height of a TEG column to dry gas. The incoing gas is NOT water saturated (due to pre heating). I see some methods (including Shell DEPs) assume saturated inlet feed. I am now using the methods in the Campbells gas course books. Does anyone know if this method relies on a water saturated gas feed, or not. I am assuming not as it does not state that, but wanted to chec as the example given has a water saturated feed. Same question for GPSA handbook I guess!


Cheers

RE: Dehydration Column with gas feed not saturated with water

Hi
Share some more data. Why are you heating the gas is it below Hydrate formation temperature?
I would ask packing vendors to do calculation for me.
