Room Temperature Ionic Liquid (Rtil) Membranes For Bio-Methane Dehumidification
… and small percentages of hydrogen sulfide and water vapor. Before this biogas—predominately bio-methane—can be converted to fuel, it must be dehumidified to become useable. Typically membrane-based gas dehumidification uses hydrophilic polymer membrane materials, such as polydimethylsiloxane …

Layer-by-layer assembly in confined geometries
… which exhibited high salt rejection and high water permeance. These membranes were compared with theoretical models and with commercially available reverse osmosis membranes.

Nanoporous monolayer graphene membranes for water purification : from concept to realization
… a new class of highly permeable membranes for water purification and desalination. Though atomically thin, graphene exhibits both exceptional mechanical strength and imperviousness to atoms as small as helium. High-density, subnanometer pores within graphene have the potential for ultra-fast …

Molecular Separation and Power Generation by Carbon Nanomembranes
… measurements of free-standing membranes with water and noble gases are studied by two methods, i.e., mass loss and vacuum mass spectrometry. The result revealed that the CNMs were intrinsically microporous. While the permeance of helium remains almost the same for 6.5 and 3.0 nm thick CNMs, …

Designing a Membrane Module for Determining the Permeance of High Fluxing Membranes and the Testing RTIL-Membranes for Dehumidification.
… operate, and take low process cost. Removal of water vapor from gases constitutes a significant expenditure of energy in our society. Dehydration via a membrane process would constitute wide spread energy savings. This thesis explores experimental issues involved with testing Room Temperature …
