Adsorption Device for Adsorbing CO2, Elemental Analyzer and Method for Removing CO2 From a Fluid Stream

Abstract

An adsorption device for adsorption of CO2 for an elemental analyzer includes a filter having an inlet for a fluid, an outlet for the fluid, and an adsorbent material through which the fluid can flow, and a heating device for heating the adsorbent material. The adsorption device is characterized in that the heating device extends along a longitudinal axis and the filter is arranged coaxially with the longitudinal axis and at least partially radially surrounds the heating device. In addition, an elemental analyzer includes a combustion reactor for burning a sample, an optional reduction reactor, an optional water separator, and a detector. The elemental analyzer further includes the adsorption device for adsorbing CO2 and a valve control for alternately passing an analysis fluid from the combustion reactor through the adsorption device for adsorbing CO2 and to the detector, or a flushing fluid through the adsorption device for adsorbing CO2.
