What is meant by the phenomenon of "gas plugging" and "cavitation" in centrifugal liquid oxygen pumps for DEAR Liquid air separation unit and what are the hazards?

What aspects do the process design of air separation equipment affect the purity of oxygen production?

Selective adsorption of molecular sieves in small air separation unit The molecular sieve selectively adsorbs molecules according to their different properties in liquid air separation plant. According to the size of the molecules, the molecules smaller than their pore size are selected for adsorption; for molecules of similar size, according to the polarity of the molecules, the more polar molecules are selected for preferential adsorption; according to the saturation of the molecules, the lar...
