Poor Boy Degasser
Poor boy degasser is an equipment to separate harmful gas in drilling mud and discharge harmful gas away from rig floor to a flaring area complete with an ignition source as per environmental regulations. It's a vertical vessel that is rigged up downstream of choke manifold during well control situation.
Height and diameter of an atmospheric separator are critical dimensions which affect the volume of gas and fluid the separator can efficiently handle. Baffles are installed inside the vessel which assist the fluid and gas separation process. Gas and fluid inlet should be located approximately at the midpoint of the vertical height of the vessel. This provides the top half for a gas chamber and the bottom half for gas separation and fluid retention.
