  • Patent number: 11136840
    Abstract: An apparatus including a superstructure comprising: a vacuum collection pod comprising a vessel with a first opening near the base, a second opening near the top of the vessel for a vacuum system, and a third opening near the top of the cylindrical vessel for a hose delivering solid and liquid materials; a rotary airlock valve coupled to the first opening; a vacuum system attached to the superstructure, wherein the inlet of the vacuum system is in fluid communication with the second opening near the top of the vessel using a vacuum line; and a solids separator below the rotary airlock valve, the solids separator comprising a drill cuttings dryer, an effluent tank configured to collect effluent from the solids separator, and a centrifugal pump configured to remove the effluent from the effluent tank. Methods of treating drill cuttings include the use of the apparatus.

  • Patent number: 9221085
    Abstract: A cleaning and separating system is provided for cleaning tanks (such as crude oil storage tanks), and other containers or enclosures. The cleaning and separating system invention fits within a limited space having a relatively small foot-print; preferably an 8 foot tall by 8 foot wide by 10 foot deep shipping container. Generally, wash fluid is sprayed into a vessel to be cleaned in order to form a slurry comprising liquid and solids. The slurry is then transferred to a cleaning and separating apparatus, where it is separated into liquid and solid components. The solids can be disposed of, while the liquids can be reclaimed.
