  • Containerized Water Electrolysis Hydrogen Generators

    Containerized Water Electrolysis Hydrogen Generators

    Containerised electrolytic water for hydrogen production is a model of alkaline electrolytic water for hydrogen production, which is attracting more and more attention in the field of hydrogen energy due to its flexibility, efficiency and safety. 

  • Helium Recovery Systems

    Helium Recovery Systems

    High-purity helium is a critical gas for the fiber optic industry. However, helium is extremely scarce on Earth, geographically unevenly distributed, and a non-renewable resource with a high and fluctuating price. In the production of fiber optic preforms, large amounts of helium with a purity of 99.999% (5N) or higher are used as a carrier gas and protective gas. This helium is directly discharged into the atmosphere after use, resulting in a huge waste of helium resources. To address this issue, Shanghai LifenGas Co., Ltd. has developed a helium recovery system to recapture the helium gas originally emitted into the atmosphere, helping enterprises reduce production costs.

  • Deuterium Gas Recovery System

    Deuterium Gas Recovery System

    Deuterium treatment of optical fiber is a crucial process for producing low water peak optical fiber. It prevents subsequent combination with hydrogen by pre-binding deuterium to the peroxide group of the optical fiber core layer, thereby reducing the hydrogen sensitivity of the optical fiber. Optical fiber treated with deuterium achieves stable attenuation near the 1383nm water peak, ensuring the transmission performance of the optical fiber in this band and meeting the performance requirements of full-spectrum optical fiber. The optical fiber deuteration treatment process consumes large amounts of deuterium gas, and directly discharging waste deuterium gas after use causes significant waste. Therefore, implementing a deuterium gas recovery and recycling device can effectively reduce deuterium gas consumption and lower production costs.

  • Argon Recovery Unit

    Argon Recovery Unit

    Shanghai LifenGas Co., Ltd. has developed a highly efficient argon recovery system with proprietary technology. This system includes dust removal, compression, carbon removal, oxygen removal, cryogenic distillation for nitrogen separation, and an auxiliary air separation system. Our argon recovery unit boasts low energy consumption and a high extraction rate, positioning it as a leader in the Chinese market.

  • Air Seperation Unit(ASU)

    Air Seperation Unit(ASU)

    An Air Separation Unit (ASU) is a device that uses air as feedstock, compressing and super-cooling it to cryogenic temperatures, before separating out oxygen, nitrogen, argon, or other liquid products from the liquid air through rectification. Depending on the user’s needs, the products of the ASU can either be singular (e.g., nitrogen) or multiple (e.g., nitrogen, oxygen, argon). The system can produce either liquid or gas products to meet different customer requirements.

  • Waste Acid Recovery Unit

    Waste Acid Recovery Unit

    The Waste Acid Recovery System (primarily hydrofluoric acid) utilises the different volatilities of the waste acid components. Through a double column atmospheric pressure continuous distillation process with precise control systems, the entire recovery process operates in a closed, automatic system with a high safety factor, achieving a high recovery rate.
