What does the model of the air separation plant mean?

The products of air separation plant have various specifications due to different outputs, varieties and forms. For the convenience of identification, a unified product model code has been compiled domestically. It consists of pinyin letters and numbers. The first (or one or two) letter represents the product category; the second letter represents the process and structural characteristics; the following is the symbol of the product's chemical elements; the number represents the production of various products, for gas, they all refer to the volume under the standard state (0℃, 0.101325MPa); the last is the variant design number.
The equipment matched with the air separation plant also has the corresponding model. For example, the type of distillation column: FON-6000/13000 indicates: F-distillation column: ON-oxygen nitrogen products; 6000-oxygen production, m³/H; 13000-nitrogen yield, m³/h Model of liquefaction equipment: YPON--200/300 means Y-liquefaction device; P-expansion machine; ON-oxygen nitrogen products; 200-liquid oxygen production L/h; 300-liquid nitrogen production L/h.
