Water vapor in compressed air can be removed through pressurization, cooling, or adsorption, while liquid water can be eliminated via heating, filtration, or mechanical separation.
Case Details
Answer: Water vapor can be removed from compressed air by pressurization, cooling, adsorption, etc., and liquid water can be removed by heating, filtration, mechanical separation, etc.
A refrigerated dryer is a device that cools compressed air to remove water vapor and obtain relatively dry compressed air. The rear cooler of the air compressor also uses cooling to remove water vapor. An adsorption dryer uses the adsorption principle to remove water vapor from compressed air.
