  • Argon Recovery System

    Argon Recovery System

    1.Argon Recovery System(ARS) focuses on the field of argon separation and recovery, covering industries such as photovoltaic crystal growing, iron and steel metallurgy and semiconductor, new-energy industries, etc. So far, it has been applied to more than 30 projects, and the argon gas processing capacity could be from 1300Nm3/h to 12000Nm3/h. 2.The exhausted argon gas is processed by dust-removal, compressed, carbon-removal and oxygen-removal, and then high-purity argon is obtained by Cryog...

  • Krypton Xenon Purification Device

    Krypton Xenon Purifica...

    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 p...

  • Waste Acid Recovery Device

    Waste Acid Recovery De...

    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. The waste acid recovery device can not only process a large amount of waste acid produced by the customer’s upstream, but also separate and recycle it, reducing the customer’s production cost. It can also properly treat the remaining wastewater and solid residues, and the water...

  • 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. After a period of time, i...
