Introduction

China is home to several leading air separation unit (ASU) manufacturers, which play a critical role in various industries by supplying high-purity gases. These units separate atmospheric air into its primary components: nitrogen, oxygen, and argon, which serve as essential raw materials across sectors such as metallurgy, chemical processing, and medical applications.

Overview of Air Separation Units

Air separation units are engineered to extract and purify components of air at large-scale capacities. Utilizing cryogenic distillation and non-cryogenic techniques, these systems achieve high-efficiency production of industrial gases. Critical parameters for evaluating ASU performance include production capacity, energy efficiency, purity levels, and operational cost.
