Abstract:
Results of an experimental study of water-vapor absorption by a stagnant layer of the aqueous solution of LiBr with admixed octanol, used as a surfactant, are described. Time dependences of temperature at various heights of the layer, time dependences of absorbed mass, and temperature and concentration profiles at various times are reported. A comparison with experimental data for surfactant-free solutions reveals an enhanced action of octanol on water-vapor absorption and an increase in the absorbent surface temperature at the initial stage of the process.
Keywords:absorption, heat and mass transfer, diffusion, solution, surfactant.
