Vacuum Degasser Operational Theory

In drilling mud purification system, vacuum degasser is widely used. Through the compulsory measures, separating gas from drilling mud, thus ensuring drilling mud good performance. Drilling mud vacuum tank degasser is one type of degasser in oil & gas drilling fluids solids control system.

Vacuum degasser can also be named drilling fluids degasser to mainly get rid of various gas of invasive drilling quickly. It is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost.

Drilling fluids vaccum degasser is used to remove the small entrained gas bubbles left in the mud by the mud/gas separator. As the second-stage solids control equipment for oilfield drilling fluids, vacuum degasser actually is used to remove little invaded gas in drilling mud. It will be set between shale shaker and mud cleaner/desander.

Operational Theory:
Vacuum degasser utilizes negative pressure by vacuum pump to withdraw entrained gases from the mud. In order for this to work, mud is pumped through a venturi, which develops a negative pressure in the vessel by vacuum pump, thus sucking mud into the unit. The choice between horizontally- or vertically-mounted units is typically based on the footprint requirements of the specific rig.


KOSUN Vacuum Degasser can quickly remove all kinds of entrained gas from the fluids. It is indispensable equipment in gas wells, prospect wells and deep wells. It is also used with various kinds of clean circulating systems for drilling. The gas/fluid separation structure of the degasser is well-designed. It can ensure efficient separation and can filter raffles in order to make sure the smooth of the blast pipe. This employs a water ring vacuum style degasser, and is used for degassing combustible gas and explosive gas.
