Abstract
A method for indirectly monitoring and controlling an electrically resistive adsorption system. Adsorption of a predetermined adsorbate is conducted while indirectly monitoring electrical resistance of a unified adsorbent element. Breakthrough is predicted based upon the indirectly monitored electrical resistance and a previously measured mass loading relationship between the resistance of the unified adsorbent element and the loading of the unified resistance element with the predetermined adsorbate. Adsorption, regeneration and cooling cycles are controlled by a controller without any direct measurement of temperature or resistance of the element and characterizations of mass loading and temperature. Systems of the invention can have no sensors that contact the element, are in an adsorption vessel, and/or are downstream adsorption vessel.
