How Does a Vacuum Degasser Work

As the second stage solid control equipment for drilling solids control system, vacuum degasser actually is used to remove little invaded gas in drilling mud. Drilling vacuum degasser will be set between drilling shale shaker and drilling mud cleaner.

KOSUN drilling vacuum degasser

KOSUN Vacuum degasser is equipped with water-ring vacuum pump and constant temperature working status. It is suitable to suck flammable and combustible gas, with safe and reliable performance.The structure of gas-water separator is reasonably designed to assure of effective separation of gas and water and free-flowing of vent pipe.Drilling vacuum degasser adopt the horizontal centrifugal force and negative pressure to remove the bubble, the handling ability is 290m³/h, the degassing ability can meet 95%-99%, it can remove the bubbles in drilling fluid effectively, avoid the well kick, blowout, and leakage fatality caused by the gas cut.

How does a vacuum degasser work

Vacuum degasser working principle: The vacuum degasser uses the suction of the vacuum pump to establish an under balanced pressure area in the vacuum cylinder and causes the drilling fluid into the hollow shaft of the rotator through suction pipe under the atmosphere pressure, and then lets the fluid spray to the walls of the cylinder from the windows on the hollow shaft, now the gas bubble cut in the mud may break and run off in the function of vacuum pump suction to a safe area due to the fluid collision and bubble separator. However, the mud will enter the drainage cavity forced by its self-weight and pass the rotator and discharge off the cylinder. In addition, drilling mud can enter the pump cylinder only through the suction pipe, and can’t be sucked in through the discharge pipe because the vacuum pump and the master motor are started simultaneously and the rotator connected to the motor will revolve at a high speed.
