Helium Regeneration Dehydration and Drying Solution
Industry Pain Points
Severe Helium Waste: Traditional regeneration consumes 15-20% of finished helium. For a 10,000-scale air separation unit, the annual loss of high-purity helium is valued at over 30 million RMB (based on a helium price of 200 RMB/Nm³).
Difficulty in Maintaining Ultra-Low Dew Point: With a molecular diameter of only 0.26nm, the adsorption efficiency of conventional molecular sieves drops sharply by 50% after reaching -60℃, resulting in a dew point fluctuation of ±10℃.
Failure Risk Under High-Pressure Conditions: Adsorbents pulverize under high pressure of 10MPa, shortening their service life from 5 years to 1 year, with a single replacement cost exceeding 5 million RMB.
Rare Gas Contamination: Trace neon (1-5ppm) in helium causes permanent poisoning of molecular sieves, reducing regeneration efficiency by 70%.
SYSTEM OVERVIEW
Yipu Helium Dehydration System achieves the following through a technology closed-loop of “cryogenic neon removal – nano-adsorption – vacuum regeneration”:
Zero Resource Waste: The helium recovered annually can fill 10 weather balloons (20 meters in diameter).
Energy Efficiency Disruption: The net energy consumption of the system is only 1/30 of that of traditional PSA.
Ultra-Purity Guarantee: A dew point of -80℃ plus 99.9999% purity, breaking through the bottleneck of semiconductor-grade helium.

Technical Principles
Yipu Four-Stage Helium-Specific Regeneration Process
Cryogenic Pre-Dehydration (Stage 1): The -80℃ helium-neon separation cold box prioritizes condensation to remove 90% of moisture and 100% of Ne, pre-lowering the dew point to -60℃.
Nano-Confined Adsorption (Stage 2): The molecular sieve has a precisely controlled pore size (0.28-0.3nm), which only adsorbs H₂O (0.28nm) while repelling He (0.26nm), increasing adsorption capacity by 3 times.
Zero Gas Consumption Regeneration (Stage 3): Recovers waste cold (-196℃ liquid nitrogen) from the air separation system to drive low-temperature vacuum regeneration, saving 95% more energy than thermal regeneration.
Helium Purity Guarantee (Stage 4): The palladium membrane purifier finally removes O₂/N₂ to ≤0.01ppm, achieving a purity of 99.9999%.
