  • Argon Recovery System

    Argon Recovery System

    High Efficiency Argon Recovery System is a collection of exhaust argon reclaiming equipment developed independently and with independent intellectual property rights by Shanghai LifenGas Co., Ltd. which includes carbon capture equipment, oxygen removal equipment, cryogenic distillation separation-nitrogen removal equipment, and auxiliary air separation equipment. It is a set of argon gas recovery systems with low energy consumption and high extraction rate.

  • Air Seperation Unit(ASU)

    Air Seperation Unit(ASU)

    Air separation unit is a kind of equipment that takes air as a raw material, turns it into a liquid state by compressing and cooling it to cryogenic temperatures, and then gradually separates oxygen, nitrogen, argon or other liquid products from the liquid air by rectification. According to users’ needs, the products of air separation units can be single products or multiple products at the same time, which can be gas or liquid.

  • Waste Acid Recovery Device

    Waste Acid Recovery Device

    Waste acid (mainly hydrofluoric acid) recovery device makes use of the different volatility between spent acid components, perform double-column vacuum continuous distillation to achieve high recovery rate.

  • Modular Energy-saving Nitrogen Generator

    Modular Energy-saving Nitrogen Generator

    Modular Energy-saving Nitrogen Generator can be also named as PSA Nitrogen Generator. It is an automatic pressure swing adsorption nitrogen that uses carbon molecular sieve as adsorbent, absorbing when pressurizing and desorption when depressurization to adsorb and release oxygen from the air, thereby separating nitrogen.

  • Ambient Oxygen Generator

    Ambient Oxygen Generator

    There are VPSA and PSA models, similar principle. Here will mainly introduce VPSA oxygen generator. It is a kind of mechanical equipment that can enrich oxygen in the atmosphere, and its working principle is to use a blower to transport the raw material air after dust removal and filtration into the absorber, and then the special molecular sieve in the absorber begins to adsorb the nitrogen component, and the oxygen component is enriched and discharged as a product.

  • Krypton Xenon Purification Device

    Krypton Xenon Purification Device

    Rare gases such as krypton and xenon have high value in many applications, but their composition in the air is very low and generally difficult to produce directly. The krypton xenon purification equipment developed by our company is based on a large air separation unit and also uses the principle of cryogenic rectification to transport the raw material LOX containing a very small amount of krypton xenon to the fractionation column for adsorption and rectification through the cryogenic LOX pump boosting. Finally, the by-product LOX obtained in the upper part of the column can be reused according to demand, and concentrated crude krypton xenon is obtained at the bottom of the column.
