Measuring hydrogen quality in real time

Enapper company uses our optical analysis measurement technology to determine the purity of hydrogen gas

In the production of hydrogen, its purity must be measured with high precision. The measurement is carried out indirectly by measuring its contamination with trace moisture and trace oxygen, which are only present in the medium in the ppm range - a challenging task for the process measurement technology used.

Measuring the purity of the produced hydrogen is a challenging task. To ensure optimal process efficiency, the measurement of traces of moisture and oxygen must be carried out reliably and in real time. Enapter was looking for a measurement solution to test the process in their AEM (Anion Exchange Membrane) electrolyzers. It was also important to Enapter to find a reliable partner able to support the company beyond gas analysis at all measurement points.

Enapper chose our solution for purity measurement. The core of quality measurement consists of a combination solution of J22 TDLAS gas analyzer and OXY5500 oxygen analyzer, which has the function of joint gas sample adjustment and is used to determine trace moisture and trace oxygen. The testing factory also installed many other pressure, conductivity, temperature, and flow parameter measurement devices to ensure smooth interaction between all components.

The realization

▖Jointly developed solution enables the required purity (industrial gas quality) to be verified

▖Enapter's AEM electrolyzer production now ready for scale-up thanks to proven process efficiency

▖All devices meet the highest safety standards and specific requirements (e.g.                    pressure transmitters with gold-plating to avoid permeation)
