Deaerators
Boiler Deaerator
Deaerators are industrial machines that are designed to remove oxygen and other dissolved gases from liquids and pumpable compounds. These machines heat water close to its boiling point with a minimum pressure drop and a minimum vent. The deaeration occurs when feedwater is sprayed into a chamber to increase its surface area. This could involve flow over multiple layers of trays. The scrubbing steam is fed to the bottom of the deaeration section of the deaerator. When steam contacts the feed water, it heats it up to its boiling point and dissolved gases are released from the feedwater and vented from the deaerator through the vent. Finally, the treated water falls into a storage tank below the deaerator. Deaerators are commonly found in industrial applications like power plants and chemical plants to reduce corrosion and extend the life of a steam-generating boiler.

Versator Deaerators
Versator deaerators’ principle of operation relies on the spreading of a thin film of aerated liquid on the inside of the rotating Versator disc under high vacuum to remove entrapped air, foam, or gas. During operation, the Versator chamber is under high vacuum and the Versator disc is rotating. The vacuum draws the aerated liquid to the Versator and into the feed assembly. At the end of the feed assembly, the spreader ring has a close clearance with the inside surface of the Versator disc. When the flow of aerated liquid passes through this clearance, it forms an even film of liquid. The rotation of the Versator disc centrifuges the thin film of liquid across the interior surface of the versator disc. While the liquid travels across the disc, the high vacuum draws off the entrapped bubbles from the film. When the deaerated liquid reaches the inner edge of the versator disc, the rotation forces the liquid up a special pipe assembly which fits closely to the surface of the disc and out of the versator chamber. The air, foam, or gas removed from the liquid exits the system through the vacuum pump’s discharge or exhaust. The versator chamber does not fill – the liquid stays within the versator disc. The versator’s operation is accomplished in a fraction of a second.
