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 & Benefits

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.

1. Test method

- Refinery Gas : ASTM D1946, D2504, D7833, DIN51666, EN 15984, UOP539, UOP603

- LPG : ASTM D2163, D2593, D4424, IP 405, ISO 7941, EN 27941

- Gascalculations : ASTM D2598, D3588, EN 589, ISO 8973

2. 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 & Options

1. 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:

- Flame Ionization Detector (FID)

- two Thermal Conductivity Detectors (TCD)

- Split/Splitless injection port

- DVLS Side Carrier with heated zones containing the valves and Molsieve columns

- Ultrasilc coated sample path

- Controlled by the Agilent OpenLab software

- PetroReporter software to report the composition and gas calculations

  (Examples of the included calculations are Liquid Volume, Molar Weight, Real 

   Specific Gravity, CV, BTU etc)

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. 

2. Options
