Chemical dehumidification by liquid desiccants: theory and experiment.

Author(s) : LAZZARIN R. M., GASPARELLA A., LONGO G. A.

Summary

Chemical dehumidification of air by a liquid desiccant in packed tower has been investigated both theoretically and experimentally for air conditioning and industrial applications. A computer model of a packed tower, able to determine the heat and mass transfer between air and desiccant, has been developed and a parametrical study was carried out considering the solutions water-lithium bromide and water-calcium chloride to determine the optimum operative conditions. An experimental apparatus including a packed tower and a desiccant regenerator has been described together with experimental results: a set of 70 experimental runs with water-lithium bromide. Data have been reported and compared against the results of the computer code simulations.
