Thermoresponsive polymer desiccants for water harvesting
… underutilised source of potable water. Polymeric desiccants are a particularly promising candidate for atmospheric water harvesting given their adaptability and scalability. However, the relative nascency of the field leaves many classes of polymers yet unexplored. This thesis details efforts into …

Studies on the Degradation of Desiccants in Temperature Swing Adsorption Processes and the Adsorptive Separation of Sulfur Compounds from Industrial Fluids
Adsorptive technologies are essential to the natural gas industry and environmental protection. In natural gas systems, adsorbents remove water, carbon dioxide (CO2), and hydrogen sulfide (H2S) from natural gas through dehydration and sweetening processes. Adsorptive separation also can remove CO2 …

Physico-chemical studies of solutions of some acids in acetone
… undertaken in which the efficiency of various desiccants was studied in producing acetone as anhydrous as could be obtained. A very efficient still was designed and the average water content of the acetone produced was of the order of 0.006 per cent which is much lower than reported by any …

Design and analysis of the power electronics system for the Lean Operation Rotary Adsorption Cooling System
… leverages thermal properties of water and desiccants to create cooling power from low-grade waste heat sources. Although low-grade waste heat comprises of the majority of the LORACS power input, electrical power is still necessary to drive critical system components such as the fans, pumps, …

Selection of the liquid desiccant in a run-around membrane energy exchanger
In this thesis, several possible liquid desiccants (aqueous solutions of LiCl, LiBr, MgCl2 and CaCl2) are investigated to find the most appropriate working fluid to be used in a run-around membrane energy exchanger (RAMEE). The liquid desiccant is one of the main components of the RAMEE and …

Heat and Mass Transfer Characteristics of Desiccant Polymers
Desiccant-enhanced air conditioning equipment has exhibited both the capability to improve humidity control and the potential to save energy costs by lowering the latent energy requirement of the supply air stream. The resulting increasing popularity of desiccant-enhanced air conditioning systems …
