Theoretical analysis of impacts of packed tower sizes on heat and mass transfer performance of cross-flow dehumidifier

Adopting structured packing as gas-liquid contact medium, with 40% of the LiCl-H2O solution as desiccant solution, obtains rules of the influences from changes in the packing tower sizes (width, height or thickness) and from changes in the filler sizes (width, height or thickness) with a constant packing volume on the performance of the dehumidifier. A theory analysis shows that when individually increasing the height, width or thickness of the filler, the height and thickness of the dehumidifier affects evidently its performance, and when the packing thickness remains a constant, the performance of the packed tower with bigger aspect ratio is superior to that with smaller aspect ratio, and when the aspect ratio is 1.1 to 1.2, the performance of dehumidifier is better.
