1.1 Zeodration and zeolites
Zeodration is a dewatering technique developed in the 1990s. It uses zeolites, i.e. a microporous mineral belonging to the silicate group, a subgroup of the tectosilicates in which they form a family including aluminosilicates.
A zeolite, whether natural or synthetic (more than 150 types of zeolite have been synthesized, and nearly 50 natural zeolites are known) is capable of selectively adsorbing or desorbing water as a function of temperature and relative humidity.
Zeolites used for zeodration take the form of microporous, three-dimensional granules about two millimeters in size. The diameter of the nanopores is around 400 picometers, corresponding to the size of...
