High-Purity Products from an Air Separation Plant
Product purities from air separation plants have been continually increasing as new and more sophisticated uses are developed. Impurity levels are measured in the parts per million range not only for some of the more exotic military and aerospace applications but also for many commercial applications. These rigid specifications apply not only to nitrogen and oxygen, the major components of the air, but also to argon, the most abundant of the rare gases, and can. apply to products in both the liquid and gaseous states.
