  • Unit for treating a drilling mud and corresponding method
    Patent number: 11465077
    Abstract: A drilling mud treatment unit (100) comprises a primary duct (10) for feeding coagulated drilling mud, an in-line flocculation system (20) for flocculating the coagulated drilling mud flowing in the primary duct (10), and at least one hydrocyclone (30) fed by the primary duct (10) and arranged downstream from the flocculation system (20). The hydrocyclone (30) has an overflow orifice (32) for receiving a liquid product resulting from treatment of the drilling mud and an underflow orifice (34) for receiving a solid product resulting from treatment of the drilling mud. The overflow orifice (32) presents an overflow diameter (Do) and the underflow orifice presents an underflow diameter (Du), and the underflow diameter (Du) is greater than 1.1 times the overflow diameter (Do).

  • Concreting facility and corresponding concreting method
    Patent number: 10113288
    Abstract: The invention relates to a concreting installation for concreting an excavation. The installation includes a concreting column having a top end arranged to be open in order to be at atmospheric pressure, and at least one controlled retention device situated at a distance from the open top end of the concreting column and adapted, in at least one configuration, to retain a volume of concrete inside the column. The invention also relates to a method of concreting an excavation.
