The bioenergy sector is setting stringent standards for biogas quality to optimize production efficiency and ensure safe operation. In response, Chromatotec has developed an online gas chromatography system. This solution, exclusively distributed by Reecotech, integrates GC-TCD gas chromatography technology along with a hydrogen generator, enabling continuous, high-precision analysis of gas components. Thanks to its fully automated design, the system minimizes background interference and optimizes the monitoring process without the need for manual intervention.

In the process of producing bioenergy, monitoring the main components of biogas—including CH₄, CO₂, H₂S, and others—is crucial for ensuring energy conversion efficiency and meeting safety standards. Traditional gas analysis systems often face limitations in automation and continuous monitoring capabilities, making them unable to promptly satisfy the real-time monitoring demands of large-scale production processes.

Chromatotec’s system applies GC-TCD gas chromatography technology, which enables the separation and quantification of gas components based on differences in their physical and chemical properties. Specifically:

• Sampling: Gas samples are drawn through a sampling tube and injected directly into the chromatography column.
• Separation: Within the separation column, gas components are isolated based on differences in adsorption properties and volatility, after which the TCD detector accurately determines the concentration of each gas without cross-interference.
• Hydrogen Generation: The system utilizes an internal hydrogen generator to supply the necessary carrier gas for the chromatography process, allowing the device to operate independently with only a power source.

System Features:

• Multi-Channel Analysis: Supports 1 to 32 analysis channels, enabling simultaneous monitoring at multiple sampling points, which is ideal for industrial gas analysis processes.
• Compact and Durable: Thanks to miniature technology and reinforced construction, the device is compact and lightweight, reducing maintenance needs and enhancing operational durability.
• Flexible Installation: The device can be mounted on a standard 19-inch rack or installed in a wall-mounted protective cabinet with protection ratings from IP54 to IP66. Additionally, the cabinet is equipped with a temperature control system to ensure stable performance under harsh environmental conditions.
• ATEX Certification: An ATEX-certified version for Zone 1 is available, designed to meet the safety requirements in explosion-risk environments.

Practical Applications:

Chromatotec’s online gas chromatography system has been successfully deployed at organic waste treatment facilities through anaerobic fermentation processes. The device is used for:

• Continuous Monitoring: Accurately tracking the concentration of the main gas components in biogas, ensuring output quality and compliance with safety standards.
• Early Warning: Automatically triggering alerts when gas concentrations exceed permitted limits, thereby supporting timely process adjustments and equipment maintenance.
• Simultaneous Multi-Channel Analysis: Monitoring multiple gas streams via independent analysis channels, providing comprehensive data on the variations of gas components throughout different stages of the production process.

Chromatotec’s online gas chromatography solution, built on a GC-TCD technology platform with an integrated hydrogen generation system, offers continuous, automated, and precise analysis. This contributes to enhanced bioenergy conversion efficiency, optimized biogas quality, and improved safety in the bioenergy production process.
