ESEGAS proudly announces the release of its next-generation Online Biogas Monitoring System ESE-6040, designed to deliver precise, continuous, and maintenance-friendly gas analysis for modern biogas upgrading applications.
To meet diverse project needs, ESEGAS offers two models of the Online Biogas Monitoring System, allowing users to select the most suitable configuration based on their process requirements.
Advanced Biogas Monitoring for Upgraded Biomethane
The ESEGAS Online Biogas Monitoring System is primarily engineered based on Electrochemical Detection (ECD) technology to achieve highly accurate H2S measurement both before and after H2S scrubbers—a critical step in ensuring gas quality and protecting downstream equipment.
To further enhance performance, the system integrates a modular multi-technology platform, combining:
- CH4 measurement via TDLAS (Tunable Diode Laser Absorption Spectroscopy)
- CO2 measurement via NDIR (Non-Dispersive Infrared)
- O2/ H2S measurement via ECD
This unique combination enables real-time, continuous monitoring of biogas composition without the need for a purging cycle, significantly improving operational efficiency and reducing maintenance requirements.
Key Features & Advantages
1. Multi-Technology Integration
A powerful combination of TDLAS, NDIR, and ECD technologies ensures high selectivity, stability, and accuracy across multiple gas components.
2. Dual-Range H2S Measurement
- High (%) and low (ppm) concentration ranges available
- Switchable measurement points (before & after scrubber)
- High-precision ECD H2S sensor with extended lifespan
3. Continuous Multi-Gas Monitoring
Simultaneous, real-time measurement of: CH4, CO2, H2S, and O2.
This enables optimized process control and improved biomethane quality consistency.
4. Long Service Life & Low Maintenance
- CH4 & CO2 sensors: up to 5 years’ service life
- Modular design for easy calibration and replacement
5. Flexible System Configuration
- Customizable gas conditioning system tailored to site conditions
- Adaptable to different process environments and installation needs
6. Industrial-Grade Design
- Stainless steel protective cabinet for corrosion resistance
- Designed for long-term operation in harsh biogas environments
- Optional explosion-proof (Ex-proof) design for hazardous areas
Application: Upgraded Biomethane Gas
This system is specifically developed for biogas upgrading processes, where accurate gas composition monitoring is essential for:
- Ensuring biomethane purity
- Optimizing scrubber performance
- Protecting compressors and pipelines
- Meeting grid injection or fuel standards
