LDetek technology to trace impurity measurements at Air Liquide hydrogen complex

LDetek’s HyDetek system will provide trace impurity measurements in hydrogen produced at Air Liquide’s hydrogen unit in Bécancour, Quebec, Canada.

The HyDetek system is used to detect traces of oxygen, nitrogen and carbon dioxide in the hydrogen produced at the plant.

It uses LDetek’s patented plasma emission detector configured with the right selective optical filters for measuring ppb/ppm oxygen, nitrogen and carbon dioxide – the main contaminants to be controlled and measured for the hydrogen produced by water electrolysis .

The gas chromatograph uses Argon as carrier gas which reduces the operation costs by a factor of 4-5 times, compared to instruments that use helium.

Air Liquide is investing in its existing hydrogen plant to install the 20 MW PEM electrolyser which will produce around 3,000 tons of hydrogen each year.

The PEM electrolyser was installed during Autumn 2020, with particular safety precautions in place due to the 2020 Covid-19 pandemic situation.
