Analyser for Measurement of Sulphur and Natural Gas Energy

Emerson introduces the Rosemount™ 700XA gas chromatograph (GC), the industry’s first single-analyser solution to provide measurement of sulphur compounds as well as energy content of natural gas, delivering a cost-effective approach to meet gas quality and heating value requirements for pipeline distribution, processing of liquified natural gas (LNG), mixed and high-purity natural gas liquids (NGLs), as well as international LNG commerce. It also satisfies operational and safety standards that protect pipelines, processing facilities, distribution systems and workers using a single, compact, transmitter-style GC.

Field-mountable for higher flexibility

While previous generations of gas chromatographs have required the purchase of separate analysers for sulphur measurement and heating value analysis, the new Rosemount 700XA gas chromatograph is equipped with a micro flame photometric detector (FPD) allowing customers to reduce initial equipment cost by as much as 50% and footprint requirements by up to 40%. The field-mountable and transmitter-type configuration of the Rosemount 700XA makes it a far more flexible gas chromatograph because it allows close-to-tap mounting, reducing sample lines and delivering faster response. In addition, the 700XA is a Class 1, Division 1, explosion-proof, ATEX/IECEX safety-rated analyser, eliminating instrument air requirements for purging or the need for additional protection. This enhances the analyser’s safety profile and allows it to fit in challenging, space-constrained environments without costly infrastructure, delivering significant installation and operational savings.

The Rosemount 700XA GC is not only a practical solution to hydrogen sulphide and energy content measurement, it can also provide hydrocarbon dew point calculations for accurate energy content reporting in two-phase gas flow streams, as well as deliver speciation and quantification of total sulphur compounds to trace levels. This allows operators to replace up to four analysers with one gas chromatograph in specific applications, simplifying the scope of analysers and reducing overall cost and footprint.
