Monitoring the integrity of natural gas pipelines during extraction and processing requires continuous tracking of Hydrogen sulfide (H₂S) and Total Sulfur (TS) levels to ensure compliance with standards and to prevent equipment corrosion. Chromatotec® provides reliable online analyzers for the safe quantification of these compounds, employing the specialized MEDOR® Electrochemical Detector (ED) to detect H₂S every two minutes. Should the concentration exceed the allowable limits, the gas gathering line can be isolated until the H₂S levels return to acceptable standards.
Product

energyMEDOR
The energyMEDOR is an automatic, isothermal gas chromatograph (autoGC-ED) specifically designed for the analysis of sulfur compounds such as H₂S, mercaptans, sulfides, total sulfur, and odor in natural gas and gaseous fuels.
The device provides online and continuous monitoring capabilities, available in two main versions:
- energyMEDOR ppm: Measures sulfur compounds at ppm levels.
- energyMEDOR ppb: Measures sulfur compounds at ppb levels.
Applications
- Detection of impurities in natural gas, LPG, propane, and butane.
- Odor removal control at ppb levels.
- Catalyst protection in chemical processes.
- Odorization control in natural gas or LPG at ppm levels.
Target Compounds
- Standard compounds: THT, H₂S, DMS, and mercaptans (MM, EM, IPM, TBM, NPM, MES, 2BM).
- Optional compounds: IBM and NBM.
Overview
During the extraction and processing of raw natural gas, midstream providers must rigorously monitor H₂S and TS concentrations. Accurate analysis of these parameters is essential to ensuring that natural gas meets quality standards, prevents equipment corrosion, and maintains the integrity of transmission pipelines.
Reecotech introduces a highly reliable, continuous online analysis solution from Chromatotec that enables the safe monitoring of H₂S, TS, and other sulfur compounds present in natural gas and gaseous fuels. The system utilizes the specialized MEDOR® Sulfur Specific Electrochemical Wet Cell Detector (ED) for H₂S detection. If concentrations exceed permitted levels, the midstream provider can promptly isolate the gas gathering line until H₂S levels are within the required specifications.
Key Features:
- High Specificity and Sensitivity: Offers highly specific H₂S and TS analysis with stable linearity and superior sensitivity to ensure accurate and reliable measurements.
- Low Maintenance Requirements: Designed for minimal maintenance.
- Internal Calibration System: Eliminates the need for standard gas cylinders through an internal calibration system featuring a calibration diffusion tube and an integrated gas generator.
- Remote Monitoring: Provides easy remote access for monitoring all parameters and controlling alarm thresholds.
- Extended Detector Lifespan: The MEDOR® electrochemical wet cell detector, including its electrolyte, boasts a lifespan of over 10 years.
- Comprehensive Technical Service Package: Chromatotec® offers an in-depth Technical Service Package (TSP) tailored for H₂S/Total Sulfur analysis systems.
