ABB Sensi+ hazardous area compliant analyser

ABB says its Sensi+ analyser offers a reliable solution that simplifies and reduces the cost of gas pipeline operation and maintenance. It is designed to enable safer, easier and more efficient pipeline monitoring and operations through a single device that can analyse up to three contaminants (H₂S, H₂O and CO₂) in any natural gas stream accurately and in real time. Its fast response also enables quick reaction to process upsets, thus helping to reduce waste and methane emissions.

Mitigating the risk and effects of natural gas contaminants can often present a challenge to natural gas pipeline operators, process industries and natural gas utilities, with companies required to manage numerous technologies and devices to obtain a complete analysis. This legacy approach is complex, failure-prone and expensive. Traditionally, each contaminant has often required a separate analyser, maintenance schedule and specific skill set to operate, validate and service.

ABB says that Sensi+ requires about six times less sample flowrate for its measurement than other technologies, reducing the total carbon emission of the analyser and natural gas wastage in the atmosphere.

The hazardous area compliant analyser needs only a simple wall-mount installation and process tie-in without complex system purging. Following installation and validation, ABB says the analyser will deliver fast and reliable measurements in the field without calibration.

The Sensi+ analyser includes ABB’s AnalyzerExpert features that provide experts with actions and insights directly from the device. Capabilities include built-in self-diagnostics, automated laser line-locking, real-time cross-interference compensation and health monitoring.
