Of course the hydrological cycle depends crucially on the evaporation of water from the warm oceans of Earth and the eventual condensation of water vapor to generate precipitation; and one of the key pathways for precipitation formation depends on the differential equilibrium vapor pressure of liquid and solid phases of water.
and "What physical principles determine the form of the curve describing equilibrium vapor pressure versus temperature?
The desiccant is regenerated by first heating it to raise its equilibrium vapor pressure.
As the fraction of calcium chloride to lithium chloride increases from 0% to 50%, the equilibrium vapor pressure for the solution more closely matches the value for pure lithium chloride.
The equilibrium vapor pressure of the hot desiccant is much higher than the partial pressure of water vapor in the air, so water evaporates from the desiccant into the air.
For a 39% lithium chloride solution at regeneration conditions, the equilibrium vapor pressure will drop by a factor of two with a 26[degrees]F (14.
