Troubleshooting of air separation equipment

Why do molecular sieves in small air separation unit use bunk beds? Molecular sieve purifiers are used in both small and large air separation plants to purify the air. carbon dioxide, acetylene, and various hydrocarbons. Some molecular sieves small air separation unit use a double bed because the adsorption capacity of activated alumina is relatively large for air with high water content, but as the water content of the air decreases, the adsorption capacity decreases rapidly. The molecular s...
