a: The application of activated alumina-molecular sieve double-decker structure to air purification system prolongs the durability of molecular sieve.
b: Filled tower is applied for the upper tower of the fractionator, thus the operating pressure of the upper or lower tower is reduced,and the product extraction yield is increased while the dissipation of energy is decreased.
c: Complete rectification technology is used for argon manufacture system. Reliable devices reduce the investment outlay and the running cost.
