  • Publication number: 20020044895
    Abstract: A reconfigurable waste treatment system having one or more waste treatment units such as scrubbers, absorption units, and thermal destruction units, is provided for treating waste supplied to the treatment system from one or more waste sources. The treatment units are selectively connected between an output and an input of a distribution manifold. Each input may be selectively connected to a desired output to achieve a desired configuration of treatment units. A venturi vacuum pump and an inert gas supply are used to assist the evacuation of waste from the waste source. The inert gas can also be used to charge the system as a whole or selected treatment devices, when not in use, to prevent the accumulation of moisture therein. A flow/pressure regulator prevents the system from being overloaded. Holding vessels are provided for collecting waste to allow staged treatment and/or sampling. The system is enclosed in a containment chamber to prevent insufficiently treated waste from escaping into the environment.

  • Patent number: 6308748
    Abstract: A container access system and method for accessing the contents of a container within a sealed containment vessel. A preferred embodiment of the access system includes a sealable vessel for housing a container to be accessed, a remotely operated container valve actuator within the vessel, and a tapping assembly positioned within the containment vessel for accessing the contents of a target container. One or more fluid seals may be made with access mechanisms and the target container. An access mechanism capable of inserting a dip tube into the container to facilitate liquid removal.

  • Patent number: 6240981
    Abstract: A drill assembly for penetrating a wall of a container is provided. The container is supported by a platform within a recovery vessel. The drilling assembly allows removal of a fluid from the container. The drilling assembly includes a tube for lining a first opening into the recovery vessel, as well as a first housing having an interior. A first adapter couples the housing to a first end of the tube to partially define a longitudinal bore. A shaft is rotatably disposed within the longitudinal bore. The shaft has one end for engagement with a drill bit with the other end for engagement with a motor. The drill bit is engaged to the shaft to penetrate the container wall, while the motor is engaged to the other end of the shaft. A first seal assembly forms a first fluid barrier between the interior and the longitudinal bore. Multiple seals may be formed between the first housing and the container. The container and the adapter may be integrally connected.

  • Patent number: 6139806
    Abstract: A venturi eduction and scrubbing system comprising a first container and a second container in fluid communication, each having a liquid treatment reagent therein. The liquid treatment reagent establishes liquid levels in the first and second containers. A waste inlet which contains waste gas or liquid to be processed is connected to at least one venturi eductor. The venturi eductors are also connected to the first container and are disposed above the liquid level of the first and second container. A pump is connected to the second container and each venturi eductor. The pump enables liquid treatment reagent to be pumped from the second container into the venturi eductors such that the waste gas or liquid is drawn from the waste inlet into the venturi eductors where it combines with the liquid treatment reagent and is thereby neutralized. The arrangement of [contains] containers and venturies provides a failsafe mechanism for preventing suckback into the waste container (which is usually the first container).

  • Patent number: 5901759
    Abstract: A fluid recovery system and method for accessing the contents of a target container. A preferred embodiment of the fluid recovery system includes an auxiliary processing vessel for housing a container to be accessed, a cylinder rupture vessel for housing the auxiliary processing vessel, and a tapping assembly positioned within the cylinder rupture vessel for accessing the contents of a target container. One or more fluid seals may be formed. The use of the auxiliary processing vessel of the preferred embodiment provides an extra level of protection against exposure to the contents of the container.

  • Patent number: 5383498
    Abstract: A cylinder rupture vessel rotates the cylinder during the rupturing process by using at least one driven roller assembly supported on a plurality of bearing surfaces. A rupture mechanism punctures the container and, when used in combination with the roller assembly, the cylinder is cut into sections. The rupture mechanism may be a water laser, a milling tool, a plasma cutting tool, a lathe tool, or at least one cutting wheel. Relative movement between the rupture mechanism and the bearing surfaces is achieved by a plurality of actuators. Treatment or decontamination of contents may be performed in the cylinder rupture vessel.
