Normally, a vacuum degasser is installed after a shale shaker and is widely used in various drilling mud systems. It is very important for recovering mud weight, stabilizing mud viscosity performance, reduce drilling cost. The vacuum pump is driven by an explosion-proof motor and produces a low-pressure condition inside the chamber that helps release the gas bubbles from the mud when the drilling mud is delivered to the degasser’s mud inlet connection. The size and capacity of the vacuum degasser will depend on the size of the drilling rig and the volume of mud that is being circulated. Vacuum degassers are relatively easy to operate and maintain.

​

The drilling mud is pumped into the degasser's mud inlet connection.

​

The first step in the degassing process is to pump the drilling mud into the degasser's mud inlet connection. The mud is typically pumped into the degasser by a centrifugal pump.

​

The mud flows through a series of baffles and screens, which help to break up the gas bubbles.

​

Once the mud is in the degasser, it flows through a series of baffles and screens. These baffles and screens help to break up the gas bubbles into smaller bubbles. This makes it easier for the vacuum pump to remove the gas bubbles from the mud.

​

The vacuum pump creates a low-pressure condition inside the degasser's chamber. This helps to draw the gas bubbles out of the mud.

​

The vacuum pump is the most important part of the degasser. It creates a low-pressure condition inside the degasser's chamber. This low-pressure condition helps to draw the gas bubbles out of the mud.

​

The degassed mud is then discharged from the degasser's mud outlet connection.

​

Once the gas bubbles have been removed from the mud, the degassed mud is discharged from the degasser's mud outlet connection. The degassed mud can then be returned to the drilling rig's mud system.
