    Determination of Impurities in Dry Chlorine

    The purpose of determining impurities in dry chlorine (after compression) is a quality control measure to avoid contamination and off-spec product batches. Alternatively, chlorine purity can also be determined by measuring absolute levels of chlorine in dry chlorine, by means of multi-wavelength UV analysis.

    Background

    The on-line analyzer system uses gas chromatography for monitoring chlorine, hydrogen, oxygen, CO2 and nitrogen.

    Typical measuring ranges

    0 – 90 %vol chlorine

    0 – 1 %vol hydrogen

    0 – 5 %vol oxygen

    0 – 2 %vol CO2

    0 – 2 %vol nitrogen

    Parameters: Chlorine purity

    Product type: Process analyzers

    Type of application process: Chlorine drying compression

    Industries: Chlor-alkali
