For the absorption of water vapor into the aqueous lithium bromide aqueous solution, eight-carbon alcohols such as 2-ethyl-l-hexanol have been commonly used to improve the absorption process. However, as additives six-carbon and seven-carbon alcohols have not been tested experimentally very much. In the present study, absorption of water vapor into the 62 wt% lithium bromide aqueous solution with several additives such as 4-methyl-2-pentanol, 2-ethyl-l-butanol, 1-hexanol, 2,4-dimethyl-3-pentanol, 4-heptanol, 2-heptanol and 1-heptanol were investigated by using a simple stagnant pool absorber. Besides using the conventional method for adding additives into LiBr solution by liquid phase, the method for adding by vapor phase also was experimented. The result showed that the method for adding by vapor phase is effective for the absorption of water vapor into the aqueous LiBr solution.
