Why does hydrogen need to be dehydrated?

Since the national "dual carbon" target was proposed in 2021, various industries have attached great importance to building a green, low-carbon, and circular development economic system. Hydrogen energy, as an emerging clean energy source, is widely used in transportation, energy storage, and industrial manufacturing due to its advantages of non pollution and high utilization rate.

Electrolysis of water to produce hydrogen is a common method for producing hydrogen, and the hydrogen produced by this method inevitably contains some water vapor. Hydrogen containing water vapor will have adverse effects on the gas end in the following aspects:
1. The moisture contained in hydrogen gas will produce condensation water when the temperature of the gas supply pipeline decreases, and sometimes even freeze, thereby affecting normal gas supply;
2. The presence of water in hydrogen gas can reduce pipeline transportation capacity, and the formation of hydrates by water vapor under certain conditions can shorten the service life of pipelines, affecting pipeline pressure and stable gas supply;
In the production processes of metal high-temperature heat treatment, powder metallurgy, microelectronic circuits, optical components, chemical synthesis, etc., the moisture in hydrogen gas can easily oxidize raw materials at high temperatures, seriously affecting product quality;

It can be seen that hydrogen dehydration is an important part of hydrogen energy utilization. High quality hydrogen can improve energy utilization, ensure subsequent production quality, and enhance production efficiency.

The hydrogen three tower energy-saving purification and dehydration device produced by Hangzhou Linuo Machinery Equipment Co., Ltd. adopts the three tower adsorption dehydration process. With full consideration of the explosion-proof level of the medium, zero gas consumption and zero emissions, and the guarantee of high-quality product performance and safety, the device effectively utilizes waste heat through heat exchange and storage between the three towers, achieving a pressure dew point of -70 ℃ and saving 90% energy consumption, safeguarding the green environmental protection cause.
