energyMEDOR

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. Two versions exist:

• The energyMEDOR® ppm (which measures at ppm levels)
• The energyMEDOR® ppb (which measures at ppb levels)

Principle

The energyMEDOR is the fully automated Gas Chromatograph for sulfur monitoring. With only a need for nitrogen carrier gas and standard electrical power, installation can be made into your current monitoring enclosure or installed in a standalone system.The energyMEDOR is equipped with two columns, heated in isothermal oven with a preset temperature of 45°C, a 10-ports pneumatic valve, electrochemical detector and an internal permeation standard or external cylinder to validate your results.The energyMEDOR automatically samples the NG from the pipeline continuously in low volume, the NG travels through a loop, the loop is injected onto the chromatographic columns where the sulfurs are separated, after the columns the sample is detected on the electrochemical detector without additional conversion or sample manipulation. Following the detection of the compounds the onboard system processes the data and provides the operator with data in either analog or digital formats. In addition the operator can review all data with the software installed into the energy MEDOR.
