Hydrogen Dehydration Unit - Guarantee of Zero Carbon Hydrogen Energy

Fossil fuels are the backbone of today's world energy market and the driving force of global economic development. However, the widespread use of fossil fuels poses a great threat to the global environment. Therefore, developing carbon free hydrogen energy is an important way for humanity to get out of the predicament.
The IEA categorizes energy into three types based on its application forms: heat, electricity, and transportation fuels. For current energy sources, only hydrogen and oil can be used simultaneously as these three types of energy. This indicates that hydrogen energy is an "advanced" energy source that can be widely used in all categories.

The necessity and selectivity of hydrogen dehydration

The utilization of hydrogen is very extensive, so the treatment of hydrogen gas is particularly important. And hydrogen dehydration is an essential part of hydrogen treatment. Moreover, different utilization methods correspond to different processing methods. Choosing the appropriate hydrogen dehydration device for the corresponding production process is the only way to reduce production costs and improve production efficiency.
The most commonly used hydrogen dehydration devices at present are the "condensing hydrogen dehydration device" and the "adsorption hydrogen dehydration device". Adsorption dehydration has a deep degree of drying and is energy-saving, but the equipment maintenance workload is relatively large; However, condensation dehydration drying does not require regeneration, is easy to operate, and can cool down the dried hydrogen gas, but its drying degree is not as good as adsorption drying.

For example, some hydrogen cooled generators require a dew point between 2 ℃ and 25 ℃, so a condensing hydrogen dehydration device can meet the demand. In the field of brazing, high-purity hydrogen gas is used as a reducing protective atmosphere for stainless steel welding, and the dew point requirement is relatively high. Generally, the dew point of hydrogen is required to be below -40 ℃, so only adsorption hydrogen dehydration devices can meet the demand.

New energy 'hydrogen' is about to become the mainstream of the world

Hangzhou Linuo Company has been researching hydrogen dehydration for over ten years, committed to contributing to low-carbon environmental protection and creating value for customers. Linuo not only values providing more assistance in selecting devices for customers, but also pays more attention to safety, efficiency, and cost issues during the use of devices by customers.

1. High security:
(1) Due to its enormous energy, hydrogen is a hazardous medium. Therefore, Linuo adopts specialized explosion-proof hydrogen electric heaters, explosion-proof fans, etc., all of which comply with GB3836- National Explosive Environment Series Standards.
(2) The system adopts explosion-proof design and strictly implements the GB3836 National Explosive Environment Series Standards to ensure safe and reliable operation.

2. Efficiency:
(1) Linuo has added an oil and gas separator at the inlet of the device to prevent oil stains and pollutants from entering the device during the hydrogen pressurization process, ensuring the effectiveness of the adsorbent.
(2) A filter has been added at the outlet to prevent adsorbent debris from entering the generator or gas pipeline, ensuring the reliable and efficient operation of the system.

3. High economic efficiency:
(1) Linuo has improved the four-way valve commonly used in hydrogen dehydration units to a pneumatic valve, which reduces the cost of customer maintenance in the later stage without affecting the device's footprint and design aesthetics.
(2) In terms of selecting adsorbents, the selection of industrial adsorbents is mainly based on their economic viability, and "adsorbent dosage" and "adsorbent regeneration energy consumption" are the main factors affecting their economic viability. Therefore, the dynamic adsorption capacity and deactivation of adsorbents become the main basis for selecting adsorbents. Linuo's professional technicians will select the most suitable adsorbent for the hydrogen dehydration unit by comparing the various indicators of different adsorbents while meeting the dew point requirements.
(3) In terms of energy consumption, Linuo can add regeneration circulation fans, electric heaters, coolers, and separators during the regeneration cycle stage according to customer needs, and design a closed zero gas consumption hydrogen dehydration device to minimize energy consumption.
