LIFENGAS OXYGEN-ENRICHMENT MEMBRANE GENERATOR
This oxygen-enrichment membrane generator harnesses advanced molecular separation technology. Using precisely engineered membranes, it exploits the natural variations in permeation rates between different air molecules. A controlled pressure differential drives oxygen molecules to pass preferentially through the membrane, creating oxygen-enriched air on one side. This innovative device concentrates oxygen from ambient air using purely physical processes.

Cryogenic Nitrogen Generator
Cryogenic nitrogen generator is equipment that uses air as a raw material to produce nitrogen through a series of processes: air filtration, compression, precooling, purification, cryogenic heat exchange, and fractionation. The generator’s specifications are customized according to users’ specific pressure and flow requirements for nitrogen products.

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.

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.

Liquid Air Separation Unit
The products of the all-liquid air separation unit can be one or more of liquid oxygen, liquid nitrogen and liquid argon, and its principle is as follows:
After purification, the air enters the cold box, and in the main heat exchanger, it exchanges heat with the reflux gas to reach a near liquefaction temperature and enters the lower column, where the air is preliminarily separated into nitrogen and oxygen-rich liquid air, the top nitrogen is condensed into liquid nitrogen in the condensing evaporator, and the liquid oxygen on the other side is evaporated. Part of the liquid nitrogen is used as the reflux liquid of the lower column, and part of it is supercooled, and after throttling, it is sent to the top of the upper column as the reflux liquid of the upper column, and the other part is recovered as a product.
