Abstract
An analysis method and apparatus are disclosed for analysing an absorption filtering medium that filters volatile organic substances in a process gas in a plant for dehumidifying polymer granules, with a fan that generates a flow of gas through the filtering medium, an analyzer of the total concentration of the organic carbon, a sensor to detect the pressure downstream of the filtering medium, in which the saturation state and/or the absorbent capacity and/or the deterioration over time of the filtering medium is determined by a comparison of the measured concentrations of total organic carbon in the flow of gas upstream and downstream of the filtering medium.
