Removal of selected pollutants from air during dehumidification by lithium chloride and triethylene glycol solutions.

Author(s) : CHUNG T. W., GHOSH T. K., HINES A. L., NOVOSEL D.

Summary

An absorber-stripper system was used to study the removal of selected indoor air pollutants during the dehumidification process, using aqueous solutions that contained 95% triethylene glycol (TEG) and 40% lithium chloride. The removal of formaldehyde, toluene, carbon dioxide, and 1,1,1-trichloroethane using these two solutions is discussed. The mass transfer coefficient was measured over a wide range of flooding conditions. The heights of transfer units calculated from mass transfer coefficients at 50% flooding are 0.36 meter for the lithium chloride solution and 0.14 meter for the TEG solution. The column efficiencies ranged from about 65 to 70% for the lithium chloride solution and from 90 to 95% for the TEG solution.
