On-line natural gas analysis.

The new gas analyzer DynamiQ-X NG2210 from Sensirion, provides fast and accurate on-line monitoring of natural gas and delivers calorific values for composition control and custody transfer purposes. Meanwhile, the DynamiQ-X NG2220 performs the same analysis for natural gas containing hydrogen at concentrations as high as 20 % using only one carrier gas. The DynamiQ-X NG2210 and DynamiQ-X NG2220 can be integrated into many locations of the natural gas infrastructure, including natural gas city gate stations, blending stations, natural gas conditioning stations, offshore systems and power-to-gas systems.

With a volume of only 10 L and weighing less than 15 kg, the instruments are easy to transport and can be deployed anywhere for analyses, if local power and gas bottles are available.

The instruments can accommodate two or three gas chromatograph (GC) units working in parallel, each performing a different GC analysis under individually optimized conditions. Each GC unit contains a state-of-the-art microchip-based injector and a thermal conductivity detector (TCD) combined with a proven microbore GC column and is set with optimal chromatography conditions. This configuration enables an accurate instrument as well as a very short analysis time of less than a minute.

DynamiQ-X is designed as a stand-alone working instrument that uses an integrated processor on a future-proof platform, so that it can carry out continuous monitoring. The instrument contains an easily exchangeable GC cartridge that allows fast local maintenance. In addition, a PC can be connected to the analyzer at any location via a network connection.

Sustainability and the facilitation of the energy transition are of global importance today. Qmicro by Sensirion has therefore developed the DynamiQ-X NG2210 and NG2220: as solutions to increase gas analysis capabilities and cover green gases, minimizing the total cost of ownership to gas distributors. The analyzers’ ability to store data for at least two years, also facilitates compliance with legislation and enables observation of long-term trends.
