Open the CIPO recordAbstract From the Canadian patent
A fluid drying system comprising a molecular sieve bed of crystalline metal aluminosilicate zeolite particles for removing water from a moisture-laden process stream. The improved apparatus and methods provide means for measuring electrical conductivity of the zeolite particles and generating a signal representative of sorbed water content. Means responsive to the signal is provided for interrupting process fluid flow through the bed at a predetermined bed water content. In the preferred embodiment a high voltage is imposed across the bed for regenerating the bed to separate sorbed water from the zeolite particles. - 1 -
