Biomethane production from biogas requires strict quality control to meet regulatory standards for gas grid injection, transportation, or liquefaction into bio-LNG. Critical parameters such as H₂S, water dew point, CO₂ and oxygen must be continuously monitored to ensure compliance and safe operation. 

Operators face challenges including corrosive impacts of impurities on pipelines and equipment, undetected wet gas leading to shutdowns or flaring, and varying national standards and grid requirements. Additionally, maintaining reliable measurements while minimizing operational costs and avoiding complex calibration procedures remains a key concern. 

A robust solution is required to verify the performance of upgrading units, ensure compliance with gas quality specifications, and provide continuous, accurate data for safe and efficient biomethane processing.

Fast and accurate biomethane quality analysis with turnkey measurement solution

The Endress+Hauser solution provides a turnkey system for continuous biomethane quality analysis, ensuring reliable monitoring of H₂S, water dew point, CO₂, O₂ and calorific parameters. Based on tunable diode laser absorption spectroscopy (TDLAS) technology with a patented differential system, it enables high-resolution measurements without interference, eliminating the need for consumables or frequent recalibration. 

Installed close to upgrading units or grid injection points, the solution ensures compliance with gas quality standards, protects infrastructure from corrosion, and supports stable operation of biomethane plants. Integrated digital services such as Netilion and Heartbeat Technology enhance maintenance efficiency, reduce downtime, and provide lifecycle support across operations.
