DVLS Refinery Gas Analyzer


Da Vinci Laboratory Solutions (DVLS) offers an automated gas solution to characterize the composition of refinery gases and liquefied gases under pressure such as LPG in 6 minutes. Next to determining the hydrocarbon content, permanent gases and hydrogen sulfide the RGA also reports calculation parameters such as Calorific and BTU Value.

Refinery gas analysis in 6 minutes

The Refinery Gas Analyzer (RGA) is based upon the Agilent GC configured with dedicated columns, valves, inlet and detectors. The multi-channel configuration allows to inject the gas samples into the separate channel at the same time. All channels operate simultaneously to determine:

  • C1 – C5 Hydrocarbons
  • C6+ Hydrocarbons
  • Permanent gases: Hydrogen, Oxygen, Nitrogen, Carbon Monoxide and Carbon Dioxide
  • Hydrogen Sulfide (analysis time of 8 minutes)
  • Extended refinery gas analysis up to BTEX (optional)
  • Customized gas components (optional)
  • Applications

    The DVLS RGA systems comply with the various standard test methods to determine the composition of the refinery and liquefied gases and to report the gas calculations.

    DVLS RGA Side CarrierThe Refinery Gas Analyzer (RGA) is based upon the Agilent GC configured with dedicated columns, valves, inlet and detectors. Da Vinci developed a DVLS Side Carrier with heated zones containing the valves and columns. This unique design reduces the system downtime during the periodical regeneration of the separation column.

     

    The Agilent GC is controlled by the Agilent OpenLab software. The DVLS PetroReporter software automates all aspects of the calibration, gas analysis through customized data reporting. Examples of the included calculations are Liquid Volume, Molar Weight, Real Specific Gravity, CV, BTU etc.
