Abstract
A method and an apparatus are disclosed for analyzing an absorption filtering medium that filters volatile organic substances in a process gas in a dehumidification plant for dehumidifying polymer granules, with a fan that generates a flow of gas through the filtering medium, an analyzer for analyzing the concentration of total organic carbon, a sensor for detecting pressure downstream of the filtering medium, in which the state of saturation 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 the total organic carbon in the flow of gas upstream and downstream of the filtering medium.
Claims9
A method of analysis including the steps of:
- generating a flow of process gas through a separator from an inlet side to an outlet side of the separator;
- detecting limonene concentrations in the process gas on the inlet side and/or on the outlet side;
- introducing the process gas coming from the outlet side into a container of material to be processed;
- detecting a limonene concentration in the gas in the container or in the gas coming from an outlet of the container;
- determining at least one operating condition based on concentrations detected in the detecting steps.
