ABB unveils advanced single-device analyzer for measuring four gas contaminants

The next-generation Sensi+ NG measures oxygen (O₂) in natural gas and biogas alongside hydrogen sulfide (H₂S), water vapor (H₂O) and carbon dioxide (CO₂).

ABB has launched Sensi+ NG, the latest evolution of its innovative multi-gas contaminant analyzer for the biogas and natural gas industries. Building on the success of its first solution, ABB continues to innovate by adding oxygen (O₂) measurement to Sensi+ NG's existing capabilities for trace-level measurement of hydrogen sulfide (H₂S), water vapor (H₂O) and carbon dioxide (CO₂). This addition enables continuous, real-time monitoring of the four most critical gas components in a single device. The 4-in-1 analyzer is engineered to support operational safety, enhance productivity and reduce maintenance, contributing to more efficient and reliable performance in industrial environments.

Natural gas contaminants are a significant challenge to an operator’s business as they represent both a safety and pipeline integrity risk due to corrosion. Sensi+ NG ensures that before biogas or biomethane is injected into the gas grid, gas quality meets strict pipeline standards, allowing for safe and reliable transmission.

ABB developed and deployed the original multi-gas contaminant analyzer as a collaborative project with a North American natural gas pipeline leader.

“The original solution was already a revolution in the market with its multi-gas analysis ability, ease of installation, operation and maintenance as well as its reduced footprint and cost of operation,” said Stefan Parmentier, Global Product Manager, Industrial ICOS at ABB’s Measurement & Analytics division. “The enhanced Sensi+ NG is a rugged and intelligent device that builds on that legacy by continuously monitoring the four most critical gas contaminants, ensuring product flow and protecting the safety of assets, environment and people.”
