Abstract
The present invention relates to a system for treating gaseous hydrogen, comprising an inlet (10a) for supplying gaseous hydrogen, a drying unit (30) with an active drying material for removing moisture from the supplied hydrogen, an adsorption unit (50) with an active adsorption material for adsorbing impurities from the dried hydrogen, and an outlet (10b) for drawing off treated hydrogen. According to the invention, the mass ratio between the active drying material and the active adsorption material is in the range of 1.5:1 to 50:1. The invention further relates to a plant comprising such a system for providing compressed treated gaseous hydrogen and a method for treating gaseous hydrogen.
Claims20
A system for treating gaseous hydrogen, comprising:
- an inlet for supplying gaseous hydrogen,
- a drying unit with an active drying material for removing moisture from the supplied hydrogen to produce dried hydrogen,
- an adsorption unit with an active adsorbent material for adsorbing impurities from the dried hydrogen to produce treated hydrogen, and
- an outlet for drawing off the treated hydrogen,
- wherein a mass ratio between the active drying material and the active adsorption material is in a range of 1.5:1 to 50:1.
A method of treating gaseous hydrogen by means of a system for treating compressed gaseous hydrogen, the method comprising:
- supplying the gaseous hydrogen at an inlet of the system,
- removing moisture from the supplied hydrogen in a drying unit of the system to produce dried hydrogen,
- adsorbing impurities from the dried hydrogen in an adsorption unit of the system to produce treated hydrogen, and
- drawing off the treated hydrogen at an outlet of the system,
- wherein a mass ratio between the active drying material and the active adsorption material is in a range of 1.5:1 to 50:1.
