How to remove the moisture from compressed air?
Compressed air is the fourth energy source for industrial manufacturers. Compressed air has air and vaporized water in it while compressed. The moisture or water should be separated from the compressed air to get the superior working performance of the industrial tools.
There are some strategies/ techniques to remove the moisture or water from the compressed air that is discussed below in detail.
Cool the compressed air:
The first strategy to remove water/moisture from compressed air is cooling down the hot air. This process condensed a significant amount of water from the air.
The condensed air can easily be separated from the air. You can use a heat- exchanger or an aftercooler to do this task.
The second strategy is that you can try over-compression pressure to remove water vapor/moisture from the compressed air. In this process, over-compression pressure is used to remove humidity and moisture from the compressed air.
The separated air allows us to expand to its usual working pressure to do its usual works. This kind of higher- compression is ideal for very small flow rates.
Use membrane drying system:
The next strategy to removing moisture from the compressed air is you can use the membrane drying system. In this system, the gas components process is being used to separate the water from the compressed air.
The separated water collected on the membrane coating fiber, while the filtered air continues flowing through the threads. And this process executed within the cylinder.
Use absorption drying system:
The next strategy that you can follow to remove/ separate moisture/water from compressed air is the absorption drying system. In this chemical system, the moisture gets dried to some liquid/ solid chemical such as sulfuric acid or sodium chloride.
Use adsorption drying system:
The last strategy that you can use to remove water vapor and moisture from the compressed air is the adsorption drying system. In this process, the vaporized water gets dried by flowing over a desiccant.
What to consider before buying a water separator for an air compressor?
Purchasing the right product can fulfill all your requirements as well as keep you tension free and save your money.
