Abstract
A method for effectively removing gas entrained in a viscous drilling fluid involves pumping the fluid with an open-center impeller pump and thereby creating a central opening in the pumped fluid into which freed gas can move coaxially with the pumped fluid; emitting the fluid in a continuous radial spray against the inner surface of the wall of a spray vessel while simultaneously creating a vacuum in the spray vessel; communicating the created vacuum area in the spray vessel with the central opening in the pumped fluid to improve gas removal and pumping efficiency in the pump; flowing the pumped fluid into an enclosed flow trough having a fluidic barrier at each end; and conducting the removed gas from the flow trough to a safe disposal area.
