The energyMEDOR® is an autoGC-ED (MEDOR® Electrochemical wet cell Detector) for the analysis and monitoring of sulfur compounds in natural gas and gaseous fuels: H2S, Mercaptans, Sulfides.
Gases Measured
- In standard : THT / H2S / DMS / Mercaptans: MM / EM / IPM / TBM /NPM/ MES
- In option: 2BM / IBM / NBM
Two versions exist:
- The energyMEDOR® ppm (which measures at ppm levels)
- The energyMEDOR® ppb (which measures at ppb levels).
Principle:
- Automatic sampling using a loop
- Automatic loop injection on metallic capillary column
- Isothermal gas chromatograph
- Detection of all compounds eluting from the column performed by MEDOR® Detector: Electrochemical wet cell Detector which is SSD Sulfur Specific Detector.
- Signal provided by electrochemical reaction between the wet cell electrolyte and the sulfur compounds
Features:
- Fully compliant with ASTM D 7493-08 : Standard Test Method for Online Measurement of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatograph and Electrochemical Detection
- Continuous monitoring with automatic online sampling
- Analytical performances:
- Specific, linear and very sensitive to sulfur compounds
- Results validation by automatic standard injection
- Long term stability using wet cell detector installed in reservoir
- Extremely low maintenance
- Very long life time detector with electrolyte, up to 10 years
- Low gas consumption, can be reduced in option
- More than 10 years data storage
- No cylinders required thanks to internal calibration tube
- Automatic control with process device
- Intelligence system with tunable and interactive alarms levels
- Powerfull VISTACHROM Chromatotec® software:
- Remote monitoring & injection control
- Full traceability with on board archiving of results and chromatograms
- QC Set up and control of threshold alarms
- Data export by MODBUS / 4-20 mA / 0-10 V
- Time stamp results
Applications:
