DVLS Impurities in Ethylene & Propylene Analyzer

To prevent poisoning of the catalysts it is essential to check the feedstock contaminants. Da Vinci developed a GC application to determine traces of Permanent Gases and Hydrocarbons in Ethylene and Propylene.


  • Applications

    The DVLS Impurities Analyzer determines traces of Permanent Gases and C1 - C6+ hydrocarbons in Ethylene and Propylene.

  • Benefits

    • Dedicated analysis of permanent gases
    • Excellent performance specifications
    • High level of automation through the OPENLAB software
    • Use of diaphragm valves eliminates the need for air actuators and saves space
  • Configuration

    The Impurities in Ethylene/Propylene application is based upon an Agilent Technologies Gas Chromatograph

    • a pre-column to backflush the hydrocarbon matrix
    • an analytical column
    • a heated Side Carrier that contains:
      • a gas sampling valve to inject the gas sample
      • several switching valves to isolate various components and to backflush
    • a Pulsed Discharge Helium Ionization Detector (PDHID) to detect the traces of permanent gases
    • OpenLAB CDS Chemstation or EZChrom software for instrument control, data acquisition, peak integration and calibration.
