  • Patent number: 11975297
    Abstract: A device for processing oil or gas well waste solids, the device including a pressurizing discharge unit having a casing. The casing includes a solids inlet and a water inlet. The solids inlet receives treated solids into a front end of the casing, where the treated solids are exposed to a reduced pressure in an internal chamber of the casing of less than atmospheric pressure. The water inlet receives water and adds the water to the treated solids in the internal chamber. The casing includes an extruder screw unit, the extruder screw unit having progressive screw sections located inside the internal chamber and corresponding to conveying mixing and pressurizing screw sections.
