Wet Gas Dryer
Wet Gas Dryer
(OP)
Hi, I am looking into a project where an existing pipeline/gas field will tie-in to a gas delivery station. However the gas is wet and I need to select a dryer. I haven't done much with driers before.
Flow rate on this pipeline is not much (normal operation is only 100,000 standard cubic feet/2830 Sm3 per day).
Also the pressure is not much either (normally 180 psi/1400 kPag.
I did some research on the net but most of the available units are for large flow rates.
Does anyone know of any proprietary gas driers that I can look into? Or any guidance?

From what i can figure, the small unit does 120,000 at 200 psig. You usually need a pair to blow the other one dry on a regular basis.
Others are available. You also need a vent or a flare as the unit dries itself by running dry gas thought it which is then flared.

Also: There's usually a good reason why everyone does it that way

I do an exercise in my class where you are using one for 250 MSCF/d at 50 psig and 100°F. In this example the dryer is able to get the water content from 743 lbm/MMSCF down to 398 lbm/MMSCF, but you have to us 30 lbm/day of salt. Where I've seen this tried for applications like the OP, the field guys get really sick of schleping bags of salt pretty quickly.
