In October 2019, Shaanxi Hanzhong Iron and Steel Group KDON(Ar)-10000/10000/300 air separation project started successfully, produced qualified oxygen products, and all indicators were in normal operation.

Air separation device is at the upstream of the process and undertakes the task of providing oxygen and nitrogen for the overall project, which is of great significance. Kaifeng Chuntai Low Temperature Co., Ltd. surmount difficulties, careful management, scientific organization, design, procurement, construction and other departments tenacious struggle, full cooperation, go all out to ensure the smooth realization of the major milestone of air separation oxygen node.

It is understood that this set of oxygen production device adopts normal temperature molecular sieve purification, air booster turbo expander to provide the cold amount required by the device, double tower distillation, and at the same time with full distillation without hydrogen argon system, product compression system, liquid storage system. The control of the whole device is completed by DCS system, and the flow and process follow the most advanced and most common international practices, and carry out the design mode on the premise of stable operation.
