Title:
MEMBRANE GAS DRYERS INCORPORATING ROTATABLE FITTINGS
Document Type and Number:
WIPO Patent Application WO/2011/106305
Kind Code:
A3
Abstract:
A membrane gas dryer includes an upstream fitting assembly, a downstream fitting assembly, a purge tube, and a sample element. The upstream fitting assembly and the downstream fitting assembly include fitting bodies and barrier sleeves. The fitting bodies and the barrier sleeves form purge plenums that are in fluid communication with the purge tube. Sealing interfaces on the fitting bodies maintain fluid-tight seals around the purge plenums as the barrier sleeves rotate about fitting bodies. The sample element includes a water-permeable membrane and passes inside the purge tube such that moisture in a sample gas flowing in a downstream direction through the sample element between the fitting body to the downstream fitting body passes moisture through the water-permeable membrane and into a purge gas flowing in the purge tube in one of an upstream direction or a downstream direction between the purge plenums.
