Cryogenic Air Separation Unit Supplier | High-Purity O₂/N₂/Ar Systems

Application Areas:

   Cryogenic air separation, capable of simultaneously producing multiple high-purity gases and liquid products, primarily serves large-scale industrial scenarios. In high-end chemical fields, it provides high-purity oxygen and nitrogen raw materials for syngas preparation and petroleum refining; in the metallurgical industry, it supports continuous smelting needs of large integrated steel plants; simultaneously, it adapts to fields such as air separation energy storage and liquid gas storage and transportation, providing guarantees for high-end manufacturing and energy projects with stringent requirements for gas purity and production capacity.

Cryogenic air separation relies on the combined principles of deep refrigeration and distillation:

   First, air is cooled to -196°C for liquefaction via expander refrigeration; then, utilizing differences in boiling points of components such as oxygen, nitrogen, and argon, precise separation of multiple components is achieved through repeated evaporation and condensation in distillation columns. Output adapts to large-scale industrial demands, with liquid product output ranging from 10 to 1,000 TPD, and gaseous products can be simultaneously produced in multiple varieties with significant production flexibility. Purity is extremely high: liquid oxygen and liquid nitrogen purity are no less than 99.5%, and gaseous oxygen and nitrogen purity can reach above 99.999%.
