Large Scale Cryogenic ASU

In today's large-scale industrial sectors such as steelmaking, chemical synthesis, and new energy, a stable, efficient, and economical supply of oxygen and nitrogen is crucial for ensuring production continuity and competitiveness. Shenger Gas understands this well. Leveraging decades of expertise in gas separation technology, we specialize in designing and manufacturing large scale cryogenic ASU units tailored for massive industrial demand. This advanced large-scale cryogenic air separation unit utilizes deep-cryogenic distillation technology to continuously and reliably separate ultra-high purity oxygen, nitrogen, and argon from air. It serves as a dependable solution for establishing modern gas plants or upgrading your gas production capacity.

Core Technology

The heart of our large scale cryogenic ASU lies in its proven and reliable deep-cryogenic air separation process. After filtration, compression, precooling, and purification, air enters our meticulously designed main heat exchangers and distillation column system. At extremely low temperatures, the unit achieves highly efficient separation through multi-stage distillation, capitalizing on the differing boiling points of air components. We place particular emphasis on optimizing the system's overall energy consumption. By incorporating high-efficiency molecular sieve purification systems, structured packing distillation technology, and advanced heat integration processes, we significantly reduce the energy required per unit of gas produced. The plant features a compact design and a high degree of automation, enabling long-term stable operation and remote intelligent monitoring.
