Hydrogen purification unit

The hydrogen purification unit uses hydrogen from water electrolysis as raw material. The hydrogen enters the gas-water separator of the purification unit, and after separating free water, it enters the deoxygenator. Under the action of palladium-platinum catalyst, impurity oxygen in the raw hydrogen reacts with hydrogen to form water vapor. After removing impurity oxygen, it passes through a hydrogen cooler and a hydrogen condenser (using cooling water) and an automatic gas-water separator to separate free condensate. It then enters the molecular sieve adsorption dryer (I) for dehumidification, and then adjusts the purification working pressure through a pressure regulating valve and removes dust through a high-efficiency filter to obtain pure hydrogen product.

Product Description

Product Introduction

The hydrogen purification device uses electrolyzed water hydrogen as raw material. The hydrogen enters the gas-water separator of the purification device, and after separating the deionized water, it enters the deoxygenator. Under the action of the palladium-platinum catalyst, the oxygen impurities in the raw hydrogen react with hydrogen to generate water vapor. After removing the oxygen impurities, it passes through the hydrogen cooler and hydrogen condenser (using cooling water) and the automatic gas-water separator to separate the deionized condensate, then enters the molecular sieve adsorption dryer (I) for dehumidification, and then adjusts the purification working pressure through the pressure regulating valve and removes dust through a high-efficiency filter to obtain pure hydrogen products.
Note: According to the actual operating conditions, the heating temperature, regeneration cooling time, and valve switching time can be adjusted appropriately. The valve switching time can also be determined according to the dew point value. An online analyzer (micro-water meter, micro-oxygen meter) can also be added at the outlet of the device to automatically detect the purity of the product hydrogen according to customer needs. Once the hydrogen is unqualified, an alarm will be triggered, and the vent valve will vent the gas. After the problem is solved and qualified, the production of qualified pure hydrogen products will automatically resume.

 

Technical Parameters

2. Raw material gas requirements: Electrolyzed water hydrogen (If it is from other hydrogen sources, please specify when ordering, the process is different)
3. Working pressure: 0.2-6MPa (Can be customized according to user needs)
4. (Hydrogen purification device) Purification efficiency: H 2 ≥99.999% Water vapor (H 2 O) ≤-80℃ Oxygen content (O 2 ) ≤1ppm Dust: After hydrogen drying, a filter with a mesh size ≤1μ is required.

 

Application Fields

High-purity hydrogen is widely used in petrochemical, electronics, electronic semiconductors, metallurgy, machinery, food processing, float glass, high-purity materials, and optoelectronic materials industries, as well as in scientific research and production departments. It can also be used as a heat treatment protective gas, and has wide applications in fine organic synthesis, aerospace, etc. For example, this machine has been successfully applied in the production of precision alloy heat treatment, aerospace, semiconductor silicon materials, silicon epitaxy, and compound semiconductors.
Note: The process design for other types of raw hydrogen gas will be based on the actual situation.
