In spite of its common use, the kinetics of liquid drying by solid desiccants is not well known, and scale-up of industrial drying processes using such materials is always problematic. In this study, the kinetics of drying of two organic liquids, dipropylene-glycol (DPG) and toluene, with some classical "type-1" desiccant materials is analysed. The experiments were done on three different scales, by using different appropriate apparatus: a laboratory stirred reactor, a small pilot and a semi-industrial pilot. The results show that dehydration kinetics is driven by a strong mass transfer limitation. Based on these results, a simple model is developed in order to design industrial drying columns from pilot data. This model is able to predict the time evolution of the water content at the outlet of the column, and the resulting simulations are in good agreement with experiments. 6 63 Oil and Gas Science and Technology http://ogst.ifp.fr/index.php?option=article&access=standard&Itemid=129&url=/articles/ogst/pdf/2008/06/ogst07125.pdf ARTICULO ddc 169121 169121 0 0 0 0 236940 BVIAPG BVIAPG 2026-03-05 200043912 0 200043912 2026-03-05 15:11:20 2026-03-05 ARTICULO
