DVLS Impurities in Ethylene & Propylene Analyzer

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

• Applications

  The DVLS Impurities Analyzer determines traces of Arsine, Phosphine & Permanent Gases in Ethylene and Propylene.

  The typical working range of the permanent gas impurities is low ppmV to 100 ppmV and Arsine/Phosphine is low ppbV to 10 ppmV.

• Benefits

  • Dedicated analysis of Arsine, Phosphine and 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 arsine, phosphine and permanent gases
  • a G-CAL permeation device to calibrate the system using the permeation tubes or a calibration gas
  • OpenLAB CDS Chemstation or EZChrom software for instrument control, data acquisition, peak integration and calibration.
