Abstract: A centrifugal degasser is provided using the principal of centrifugal force to separate gas from a gas-cut flowable material such as drilling mud. The device passes a gas-cut material through a centrifugal force field to accomplish the degassing. The invention contemplates the slurry flowing through the degasser by entering it through the top and flowing downward or entering from the bottom and flowing upward. In either case the slurry moves through the force field to accelerate gravity settling of the continuous phase of the flowable material and to accelerate buoyant force gas bubble rising time.
