Abstract: A portable container cleaning apparatus comprising: a cleaning container comprising at least one cleaning platform lift door unit; a cleaning unit comprising at least one cleaning nozzle; a pump and piping system; and, a filtration system, wherein a portable container is capable of being loaded into a cleaning position inside said cleaning container via said cleaning platform lift door unit for cleaning by said cleaning unit, and said cleaning unit is in fluid communication with said filtration system via said pump and piping system.

Abstract: An improved portable fluid storage tank comprising an enclosure having a bottom wall upon which the tank rests, a front or forward end, a back or rear end, a pair of opposed, vertically extending side walls, a top wall, and at least one recessed channel formed in said top wall whereby a walkway is formed to allow an operator to safely maneuver on top of said tank. In a further embodiment, a system of portable storage tanks is described wherein the walkways of two or more said improved portable storage tanks are connected thereby creating a walkway network between said improved portable fluid storage tanks.

Abstract: The present invention relates to a system, method and apparatus for the extraction of hydrocarbons from contaminated solids. The method for separating hydrocarbons from solids comprising exposing the solid to a heat source of sufficient temperature to release substantially all of the hydrocarbon and water from the solids as volatile vapors, condensing at least a portion of the hydrocarbon vapor, and condensing the water vapor. The apparatus for extracting hydrocarbons from solids comprises a heat source capable of reaching temperatures sufficient to vaporize substantially all of the hydrocarbons in the contaminated solids and at least one separation tank in fluid communication with an outlet of said heat source for condensing at least part of the hydrocarbons. The present invention also relates the system for applying said method to said apparatus to extract and recover hydrocarbons from contaminated solids.

Abstract: A tank cleaning device is provided, comprising a base member; a conduit attached to the base member having an inlet, an upper outlet, and a lower outlet; and a plurality of adjustable legs connected to and extending below the base member. The inlet of the conduit accepts a cleaning fluid, and a cleaning nozzle is attached to either the upper outlet or the lower outlet. A method of cleaning the tank is also provided, comprising placing the mounting device at a first location, spraying the tank with the cleaning fluid until a selected portion of the tank is cleaned, discontinuing the supply of cleaning fluid, and then repositioning the mounting device to a second location within the tank and resuming the supply of cleaning fluid. Multiple mounting devices may be employed and periodically repositioned within the tank to achieve quick and effective cleaning.

Abstract: A separation device for removing solids from an input stream is provided, comprising a vessel, such as a production vessel or storage tank, having an inlet for receiving an input stream containing fluids, such as oil and water, and solids, such as sand and silt. The vessel also includes a fluid outlet and a drain outlet. An optional fluid recirculation and injection device is mounted inside the vessel and delivers fluid to facilitate removal of the solids through the drain outlet. The vessel also includes an agitation or flighted device mounted adjacent to the drain outlet for contacting and dislodging solids which have settled within the vessel. The agitation device includes a rotatable shaft driven by a motor, and an agitation element, such as an auger, to break up the solids and move them toward the drain outlet. A method of removing solids is also provided using the auger device.
