  • Argon Recovery System

    Argon Recovery System

    The Highly Efficiency Argon Recovery System is a set of exhaust argon reclamation equipment developed independently and with independent intellectual property rights by Shanghai LifenGas Co., Ltd. It includes carbon capture equipment, oxygen removal equipment, cryogenic distillation/separation nitrogen removal equipment, and auxiliary air separation equipment. This is an argon gas recovery system with low energy consumption and high extraction rates.

  • Air Seperation Unit(ASU)

    Air Seperation Unit(ASU)

    An air separation unit takes in air as a raw material, liquefies it by compressing and cooling it to cryogenic temperatures, and then gradually separates oxygen, nitrogen, argon and other products from the liquid air through rectification. The air separation unit can output either single or multiple products, in either gas or liquid form, depending on the user’s needs.

  • Waste Acid Recovery Device

    Waste Acid Recovery Device

    The waste acid (mainly hydrofluoric acid) recovery device uses the different volatilities of the spent acid components to perform double-column vacuum continuous distillation, achieving a high recovery rate.

  • Modular Energy-saving Nitrogen Generator

    Modular Energy-saving Nitrogen Generator

    The modular energy-saving nitrogen generator, also known as a PSA nitrogen generator, is an automatic pressure swing adsorption system that uses a carbon molecular sieve to adsorb and extract oxygen from air, thereby separating out the nitrogen.

  • Ambient Oxygen Generator

    Ambient Oxygen Generator

    The ambient oxygen generator, including both VPSA and PSA models, is equipment that can enrich the oxygen content in the atmosphere. Its working principle is to use a blower to transport the filtered and dust-removed raw air into an absorber, where a specialized molecular sieve adsorbs nitrogen from the air, allowing the oxygen to be 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 concentrations in the air are 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. This allows the raw material, liquid oxygen (LOX) containing a very small amount of krypton and xenon, to be transported to the fractionation column for adsorption and distillation. This is achieved through the use of a cryogenic LOX pump to boost the pressure. Finally, the by-product LOX obtained from the upper part of the column can be reused as needed, and a concentrated crude krypton-xenon mixture is obtained from the bottom of the column.
