Physical Properties of LiCl Solution for Vacuum Regeneration

Abstract

Boiling regeneration of dehumidified solution under vacuum condition has a good research prospect due to its advantages of being free from environmental effect and low requirement on the temperature of the heat source. However, the physical parameters of the solution under vacuum condition are not sufficient at present. In this paper, the surface vapour pressure and boiling point of the LiCl solution under vacuum condition are studied, and the variation of the solution viscosity and surface tension with the concentration are given, which has a certain guiding significance to the study on the vacuum regeneration of the LiCl solution.
