ZeroGas vacuum deaerators are arranged on a vertical degassing tower that incorporates a storage section.

In the vacuum deaerator, oxygen and carbon dioxide are removed from the liquid phase by creating vacuum conditions. The reduction of the partial pressure in the gas phase is the driving force that moves dissolved oxygen into the gas phase. A vacuum is created in the degassing tower through the action of pumps, either with or without the assistance of additional air-driven ejectors. The water is fed to the top of the degassing tower and falls across metallic or plastic rings down to the storage tank.

Our vast experience in supplying and commissioning vacuum degassers for the most demanding applications includes district heating and injection water treatment upstream in the oil sector.

To keep crude oil flowing through most of the wells, sea or river water must be pumped into the oil basin to be used as “flooding water.” To prevent any bacteria proliferation in the oil basin, vacuum degassers are used to reduce the concentration of oxygen down to negligible levels.

Our experience in vacuum degassing in the most challenging applications is available to you and your team. Take a look at the vacuum degassing solution offshore we supplied in the Baltic Sea to learn more.
