Clora Online Chlorine Analyzer

Online Chlorine Analysis in Liquid Hydrocarbon Process Streams

  1. General Details

    Chlorine contributes significantly to the corrosion of plant equipment and must be treated accordingly. With ever-changing crude quality and potential for process upsets, chlorine levels can shift quickly, making real-time analytical results invaluable. Powered by MWDXRF®, Clora® Online uses ASTM D7536 technology and delivers real-time, continuous analysis of total chlorine from 0.2 ppmw up to 3000 ppmw. By monitoring desalted crude, a plant can optimize performance and immediately see impacts of crude changes (including organic chloride). This process analyzer is ATEX and NEC certified for hazardous area locations.


    Applications:

    • Upstream desalting, refining, power generation and effluent management
    • Total chlorine analysis in:

      – Raw and desalted crudes

      – Water and effluent streams

      – Refinery process streams

      – Finished product


    Features:

    • Uses ASTM D7536 technology
    • ATEX Zone 1 and NEC Cl | Div 2 Certified
    • LOD: 0.2 ppmw in hydrocarbon matrices @ 300 s
    • LOD: 0.6 ppmw in aqueous streams @ 300 s
    • Dynamic range: 0.2 ppmw – 3000 ppmw
    • Calibration is linear up to 3000 ppmw and one calibration curve runs all hydrocarbon matrices
    • Robust industrial design: wall mounted or stand alone

    Benefits:

    •  Continuous, real-time analysis
    • Rapid response to upsets
    • Easy to use with intuitive touch screen interface
    • Direct measurement in ppm wt
    • Low Maintenance: no consumable liquids, gasses, combustion, or sample conversion
    • Not sensitive to sample temperature changes
