Abstract: Water removal from humidified air and other water-laden gases may be complicated due to the need for large and expensive capital equipment or use of powder-form desiccants that may lead to pressure drops, poor throughput and energy-intensive recovery of water. Reversible water-absorbing constructs may alleviate these difficulties and comprise: a phase change polymer exhibiting a reversible hydrophilic-hydrophobic phase transition, and at least one additional material in contact with the phase change polymer, such as a water-sorptive material. The phase change polymer and the at least one additional material are formed as a plurality of filaments. Filaments formed from the phase change polymer may be generated through an electrospinning process, which may be arranged in various higher level constructs, such as in fibers, fabrics and non-woven filament mats capable of absorbing water from humidified air or other water-laden gases.

Abstract: A system and method utilize one or more fans each having fan blades. The fan blades have a desiccant material on an outer surface. The desiccant material is operable to adsorb airborne moisture in an ambient airflow and desorb moisture in a heated airflow. The fan blades are operable to drive one or both of the ambient airflow and heated airflow via rotation of the fan.

Abstract: A gas separation system has system input inlet configured to receive a stream mixture including a target gas, one or more spray generators positioned to spray a non-sprayable liquid to change a concentration of the target gas in the non-sprayable liquid, one or more system outlets positioned to outlet an output material, wherein at least one of the system outlets outputs a material having a lower amount of the target gas than the input stream mixture, and a recirculating path connected to the one or more outputs and the input inlet to allow recirculation of the non-sprayable liquid. A method of performing gas separation includes absorbing a target gas from an input stream in a non-sprayable capture liquid, and releasing the target gas in an output gas stream by spraying the non-sprayable capture liquid into a heated volume using a spray generator. A method of performing gas separation includes receiving an input stream that includes a target gas, using one or more spray generators to apply a non-sprayable liquid as a spray to the input stream to change a concentration of the target gas in the liquid, and outputting the liquid with the changed concentration through an outlet.
