Performance analysis of hybrid solid liquid desiccant material: Dehumidification and CO₂ absorption

Abstract

As the population and living standard of human beings rises, energy requirement also increases rapidly. In developing country like India, a major part of energy requirement is fulfilled by thermal power-based plants. It generates pollutant gases and water vapor responsible for global warming and other environmental problems. To overcome these problems in controlled area, a continuous experimental investigation has been performed based on the hybrid solid-liquid desiccant (HSLD) containing CaCl 2 (0.33 M), lithium chloride (0.66 M), titanium dioxide (0.026 M), silicon dioxide (0.316 M), copper oxide (0.067 M) for dehumidification, and CO 2 removal from the atmospheric air. In addition, CO 2 removal capacity of HSLD has been performed from CO 2 + air mixture containing variable CO 2 to air as 0.33-5.46 (wt ratio). Present study suggest relative humidity of air is reduced from 75% to
