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. 

Benefits

• High quality GC hardware
• Fast analysis of refinery gases
• Maximum system uptime 
• Representative injection of liquefied gases
• Standard methods compliance
• Automated reporting of gas calculations
• Guaranteed analyzer performance

Configuration

The DVLS Refinery Gas Analyzer is based upon the Agilent 8890 Gas Chromatograph (GC) with built-in intelligence and electronic pneumatic control (EPC). The Agilent Gas Chromatograph consists of three different channels; each channel is configured with its own detector. The system includes:

• a Flame Ionization Detector (FID)
• two Thermal Conductivity Detectors (TCD)
• a Split/Splitless injection port
• a DVLS Side Carrier with heated zones containing the valves and Molsieve columns
• Ultrasilc coated sample path
• PetroReporter software to report the composition and gas calculations

Da Vinci developed a DVLS Side Carrier with heated zones containing the valves and columns. This unique hardware design includes a built-in colum conditioning which reduces the system downtime during the periodical regeneration of the Molsieve columns.

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.

Options

To customize your refinery gas analysis we offer various hardware options:

• a Mode for extended refinery gas analysis up to BTEX
• Hydrogen Carrier
• a Liquid Sampling Valve (LSV) for the sampling of liquefied gases
• a Pressure Station for the sampling of (liquefied) gases
• a Vacuum Pump for sample introduction through the use of Tedlar bags
• Inert Valves for the use of corrosive gases
• Fourth Channel containing:
  • GSV- Column – Detector
  • Methanizer for the trace analysis of CO/CO2 conform UOP603 or SCD/PFPD for Sulfur analysis
