Abstract
Removal of small amounts of water from organic
liquids is normally handled by adsorption or by azeotropic
distillation. The latter method is well
documented and analysis or design is straightforward
so long as the azeotrope is properly defined. The
former method, adsorption, is not well documented or
understood even though it is practiced fairly extensively.
The purpose of this paper is to review
the state-of-the-art on adsorptive drying of liquid
organics having limited water solubility and to make
appropriate comparisons with the distillation method.
A few other drying methods will also be discussed.
Included in the presentation will be information
on the determination of adsorption isotherms
and the modeling of adsorption kinetics. A description
of an experimental program at The
University of Texas at Austin will also be given.
