ABSTRACT:
Disclosed are an apparatus and method for degassing drilling mud. The apparatus includes a pressure vessel having an inlet and an outlet. A vertically oriented tube is axially rotatably mounted within the pressure vessel. The tube has an open lower end communicating with the inlet and a closed upper end having a plurality of ports therebelow. A rotor is mounted to the tube for rotation therewith and includes an upwardly facing conical surface below the ports which slopes upwardly and outwardly toward a rim. An impingement ring is mounted within the pressure vessel about and radially spaced apart from the rim. An upwardly facing conical film tray is mounted within the pressure vessel below the rotor and impingement ring and has a surface sloping downwardly and inwardly toward a central opening. A collecting bowl is mounted below the central opening for rotation with the tube. The collecting bowl includes an upwardly and inwardly turned wall. A pickup tube is mounted within the pressure vessel for communication with the outlet of the pressure vessel. The pickup tube includes an inlet positioned within the collecting bowl adjacent the wall. A pump is provided for creating a substantial vacuum within the pressure vessel and a motor is provided to rotate the tube, thereby to rotate the rotor and collecting bowl.
