“…Most of the membranes thus far have been constructed in a composite structure comprising support layers and an active layer [6,13,14,16]. The support layers provide the high mechanical strength and eventual chemical stability to the membrane.…”

“…Composite membranes have higher permeability and mechanical strength than single-layer membranes with the same thickness. Therefore, the development of inexpensive and high performance composite membranes has attracted much research interest in the field of isothermal air/gas dehumidification [1,6,[12][13][14]16].…”

a b s t r a c tThin and robust composite membranes comprising stainless steel scaffold, fine and porous TiO 2 and polyvinyl alcohol/lithium chloride were fabricated and studied for air dehumidification application. Higher hydrophilicity, sorption and permeation were observed for membranes with increased lithium chloride content up to 50%. The permeation and sorption properties of the membranes were investigated under different temperatures. The results provided a deeper insight into the membrane water vapor permeation process. It was specifically noted that lithium chloride significantly reduces water diffusion energy barrier, resulting in the change of permeation energy from positive to negative values. Higher water vapor permeance was observed for the membrane with higher LiCl content at lower temperature. The isothermal air dehumidification tests show that the membrane is suitable for dehumidifying air in high humid condition. Additionally, results also indicate a trade-off between the humidity ratio drop with the water vapor removal rate when varying air flowrate.

“…Dehumidification can be accomplished using cooling cycles [1], including those based on vapor capillary condensation effect [2,3], vapor absorption [4] or adsorption [5] with desiccants and exploiting membrane separation equipment [6]. Among the methods mentioned, gas, dehumidification by vapor absorption with hygroscopic liquids gained most widespread use due to low energy consumption, the absence of water droplets and its high efficiency.…”

We report the application of porous polypropylene hollow fiber membranes with 100×500 nm slit pores in membrane contactor for air dehumidification using triethylene glycol (TEG) as an absorbent. Experiment geometry with gas flow through the lumen of fiber and absorbent circulated on the shell side was utilized to enhance water vapor stage cut. The influence of gas flow rate, liquid circulation rate and water content in triethylene glycol solution on the performance of membrane contactor was studied. The obtained results reveal that the limiting step of water vapor absorption for lumen gas flow configuration is the diffusion of water into TEG volume. Using dry TEG solution and high circulation rate the dew point of feed gas can be decreased down to ∼ −30• C for the membrane contactor performance of 30 -60 l/(m 2 h), while with reducing dew point requirements to −10• C the performance of the contactor over 1 m 3 /(m 2 h) is achievable.

“…A földgáz szárítására többféle módszer létezik [69,70], a leggyakoribbak az abszorpció és az adszorpció [71], de megemlíthető még a membrános eljárás [72,73] is. Abszorpció esetén folyékony szárítószert alkalmaznak, amely az esetek döntő többségében trietilén-glikol, ritkábban di-, esetleg tetraetilén-glikol (rövidítéseik rendre TEG, DEG, TREG).…”
