APPARATUS AND METHOD FOR CONVEYING DRILL CUTTINGS

摘要

An apparatus and method for conveying drill cuttings, the 5 apparatus comprising a vessel (1103) for receiving drill cuttings to be conveyed, a metering screw (1107) and a discharge line (1014), the metering screw (1107) for moving the drill cuttings from the vessel (1103) into said discharge line (1014), and at least one gas inlet 10 (1109) for providing positive pressure to facilitate movement of the material through the discharge line (1014) characterised in that the apparatus further comprises a pressure sensor (1109c) for sensing pressure in the discharge line (1014), and control apparatus (PD) 15 for automatically controlling the metering screw (1107) in response to a pressure sensed by the pressure sensor apparatus.
