Water removal membranes

Water removal membranes

Water removal membranes

(OP)
My objective is to separate water from wet air for an air conditionning system and i'm searching for manufacturers of membrane fibres that could be used for this application. Furthermore, is there anybody who can give me any information about the maximum temperature that this type of membrane can handle?

RE: Water removal membranes

Are you looking to reclaim the water, or only to dehumidify the air?

RE: Water removal membranes

Second set of questions (#1 needs to be answered as well)

high volume or low volume application?
how dry is dry?
can you afford some relative loss of O2?

RE: Water removal membranes

(OP)
I'm looking to dehumidify air only; the volume of air to be thread is about 29 kg/min and the humidity of the air is about 19 g/kg; the goal to reach is 7g/kg. We cannot accept some relative losses of O2 because this air is sent directly to the people.

RE: Water removal membranes

Must it be a membrane, or can you flow through a dessicating chamber?  Silica Dessicant (Like those "sugar" packets used to keep shoes from getting musty and keeping your beef jerky from growing critters) is relatively cheap and often times reuseable after drying in an oven.  I also have a colleague who worked in a cartridge designed to remove water from dry cleaning solvents to recycle the solvent.  It worked basically the same as a disposable diaper, super absorbent polymer powder.  The product was patented by Proctor and Gamble, but I'm not sure who markets it, or what the trade name is.
