Hydrogen can be given off as a by-product of steel mill and chemical plant operations, and is also obtained from fossil fuels for industrial use. Some common applications in which hydrogen is used include desulfurization in the oil refining process, heat treatment in metal processing, as a reducing atmosphere and carrier gas in semiconductor manufacturing, and as a next generation fuel source. 

Why is gas monitoring necessary?

  • When a gaseous mixture containing 5% or more of oxygen and 4% or more of hydrogen is ignited, it can result in a hydrogen explosion.
  • Because it has the lowest density of all gases, hydrogen can leak very easily.
  • We need to know the grade of hydrogen used when forming substances and compounds.

    HOT TOPICS

    All eyes are on hydrogen and its potential as a new generation energy source on the path toward carbon neutrality. At the present stage, hydrogen is being used to develop fuel cells that generate electricity through a chemical reaction between hydrogen and oxygen. It is also being used in conjunction with fossil fuels to generate power in a process known as hydrogen co-firing. In order to use hydrogen co-firing as a stable energy source, it is important to control variations in calorific value as well as the mixing ratio with other fuels.
