H2S, mercaptans, THT, sulphides, total sulfur and odor measurement
Online analysis and monitoring of sulfur compounds in natural gas
Description :
The energyMEDOR is an automatic and isothermal gas
chromatograph dedicated to sulfur compounds analysis (H2S, mercaptans and sulphides) in different matrices.
Two versions exist : the energyMEDOR ppm which measures at ppm levels and the energyMEDOR ppb which measures at ppb levels.
Principle :
- Loop injection by automatic valve
- Detection is made by a gas-liquid reaction
- Sulfur specific detector – no interferences
- The detector life is in excess of 10 years
Features :
- Online, continuous sampling
- No interference from other compounds
- Low maintenance instrument – detector life may be up to 10 years
- Automatic Validation of results by Internal Permeation Tube
- Modifiable threshold alarms – High / Low alarm for odorising processes
VISTACHROM ® software
Chromatotec developed software system enables :
- Remote monitoring & injection control
- Full traceability with on board archiving of results
- QC Set up and control of threshold alarms
- Export of data MODBUS / MGS1 / 4-20mA / 0-10V
