Monitoring natural gas quality

News Editor
ABB’s Sensi+ analyser offers a reliable new solution that simplifies and reduces the cost of pipeline operation and maintenance. It enables safer, easier and more efficient pipeline monitoring and operations through a single device that can analyse up to three contaminants (H2S, H2O, 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.
“With the new Sensi+ and the natural gas chromatograph series, we can offer customers a comprehensive gas quality solution that combines composition and contaminant measurements into a compact, modular, economical and reliable system,” said Jean-Rene Roy at ABB. “The new analyser also helps customers to meet custody transfer requirements, minimise internal corrosion in system infrastructure and prevent physical damage to mission-critical assets.”
Its makers say that Sensi+ requires about six times less sample flowrate for its measurement than some other technologiesm reducing the total carbon emission of the analyser and natural gas wasting in the atmosphere. This reflects ABB’s commitment towards enabling a low-carbon society by helping to reduce carbon emissions and support sustainable operations in key industries.
Natural gas pipeline operators have the critical task of managing their installed base of analysers to ensure the necessary reliability, system integrity, and performance for their custody transfer, emissions reduction and process control applications. The hazardous area compliant analyser needs only a simple wall mount installation and process tie-in without complex system purging. Following installation and validation, the analyser will deliver fast and reliable measurements in the field without calibration.
