Atmospheric Degassers sit in the mud tank and consist of an elevated spray chamber and a submerged centrifugal pump. The gas-cut mud is pumped to the spray chamber at high velocity through a disc valve. The mud strikes the inside wall of the spray chamber with enough force to drive most of the entrapped gas out of the mud. The removed gas is usually discharged to atmosphere at pit level and the degassed mud returned to the active system. These devices are simple to operate and maintain, but their effectiveness is often limited by the ability of the centrifugal pump to handle gas-cut mud. A second method of degassing is provided by the use of a vacuum.

Vacuum-type Degassers

Vacuum-type Degassers separate gas bubbles from drilling mud by spreading the gas-cut mud into thin layers and then drawing off the gases with a vacuum pump. The mud is usually thinned by flowing it over a series of baffles or plates. Vacuum degassers are normally skid-mounted and installed on top of the mud tanks.

Some models incorporate more than one degassing technique within a single unit. For example, one degasser spreads the mud into thin sheets through centrifugal force, sprays the mud onto an impact shield for residual gas separation, and draws off the gases with a vacuum pump.
