How ABB Sets a Competitive Benchmark in Biogas and Natural Gas Contaminant Monitoring

ABB has introduced Sensi+ NG, a next-generation multi-gas contaminant analyzer designed for biogas upgrading facilities, natural gas processing plants and pipeline injection points. The device strengthens operational safety and gas quality assurance by offering continuous, real-time measurement of four critical contaminants—oxygen (O₂), hydrogen sulfide (H₂S), water vapor (H₂O) and carbon dioxide (CO₂)—in a single compact system.

A 4-in-1 System that Reduces Operational Complexity
Natural gas contaminants pose significant risks to safety and pipeline integrity. Sensi+ NG consolidates several measurement functions traditionally performed by multiple analyzers, enabling operators to monitor trace-level contaminants without consumables, frequent calibration or complex maintenance. This integration reduces equipment count, minimizes product waste and helps maintain uninterrupted operations, even in remote or rural biogas facilities where reliability and simplicity are essential.

Enhanced Performance Powered by OA-ICOS Technology
The system builds on ABB’s OA-ICOS laser-based measurement technology, delivering rapid response times, stable readings and minimal long-term drift. By adding oxygen measurement to the established H₂S, H₂O and CO₂ capabilities, the upgraded solution enhances process optimization and early fault detection, supporting operators in preventing upset events and avoiding false alarms or unnecessary shut-ins.

Designed for Gas Grid Compliance and Real-World Industrial Conditions
Sensi+ NG helps ensure that biogas and biomethane meet stringent pipeline quality requirements before injection into the grid. The analyzer’s rugged design and ability to run multiple applications from a single device stem from ABB’s earlier deployment of the technology in collaboration with a major North American pipeline operator. The improved version strengthens that foundation by continuously monitoring the contaminants that matter most for asset protection and environmental safety.

Differentiation in a Competitive Market
What distinguishes Sensi+ NG from conventional analyzers is its ability to combine multi-gas capability, fast laser-based detection, negligible cross-interference and low maintenance into one instrument. Competing systems often require separate analyzers, higher maintenance cycles or consumable-based methods, increasing overall operational burden. Sensi+ NG offers a smaller footprint and lower total cost of ownership while improving productivity and regulatory compliance.

A Streamlined Approach to Reliable Gas Quality Measurement
For operators seeking a dependable, efficient way to monitor contaminant levels in natural gas or biogas streams, Sensi+ NG provides a practical solution. By merging four key measurements into a single device and maintaining high accuracy with minimal upkeep, ABB positions this technology as an effective alternative to more complex or fragmented monitoring systems commonly used in the industry.
