The role of molecular sieves in gas separation


2025-06-13

  Beyond air purification, another important role of molecular sieves in air separation equipment is gas separation. The pore size and structure of the molecular sieve determine its ability to selectively adsorb certain gas molecules, thereby achieving the separation of different gases. Specifically, the role of molecular sieves in gas separation includes:
  Nitrogen separation: In cryogenic air separation equipment, molecular sieves can effectively separate nitrogen from the air, enriching nitrogen through selective adsorption and ultimately extracting high-purity nitrogen.
  Oxygen purification: Molecular sieves also play an important role in oxygen purification. Through multi-stage separation, molecular sieves can remove impurities from oxygen to ensure high purity of oxygen.
  Rare gas recovery: Air separation equipment can also use molecular sieves to separate and recover rare gases such as argon and neon. These gases have important applications in industrial production, and the use of molecular sieves improves recovery efficiency and purity.
