ABSTRACT:
Apparatus for removing gas from drilling mud comprising a housing defining a chamber having a mud inlet at one end and a processed mud outlet and a gas outlet means at the other end. The mud outlet and the gas outlet means are spaced radially outward from the central axis of the chamber. A shaft is located within the chamber along its central axis with a plurality of angularly spaced blades attached thereto along its length. The outer ends of the blades have flexible members attached thereto. Drive means is provided for rotating the shaft and hence the blades for spinning the mud received through the inlet against the inside surface of the wall of the housing as a thin layer and moving the mud as a thin layer to the other end of the chamber for allowing the gas in the mud to separate. One or more feedback conduits are provided for facilitating control of the thickness of the mud layer on the inside surface of the wall of the housing and for preventing mud from flowing through the gas outlet means.
