Extended reach sluicer systems, devices, and methods for breaking up and retrieving chemical, radioactive, hazardous materials and/or other waste and/or other material from storage tanks with mechanical arms and nozzles to break up and transfer tank material. And this invention can work with tanks having high temperature or low temperature conditions.

A dual-purpose tank container is provided, designed for transporting unrefined or refined fluid within the same internal space, eliminating unproductive deadheading. The tank container includes an inner tank in a frame, and outer insulation shell, the tank being equipped with at least one diaphragm so that a fluid, for example crude oil or diesel fuel, can occupy inner space without risk of contamination from a residual fluid. The high viscosity unrefined fluid can be almost completely drained using fluid draining channels present on the diaphragm surface, increasing transportation economy and eliminating any residual fluid pockets. At least one inlet present on the upper tank body supplies a solvent vapor/fluid to condition the space between the diaphragm and the tank wall, thereby preventing sticking of the diaphragm to the tank inner surface.

The present invention relates to a modular cleaning hydrocarbon storage tanks system, as well as a cleaning process which allows recovering crude oil from the waste sludge contained in the hydrocarbon storage tanks. Moreover, the present invention relates to the use of chemical mixtures applied during the hydrocarbon storage tanks cleaning process. The invention allows the recovery of crude oil from the waste sludge contained in said tanks.

A zonal cleaning system for a hopper trailer. The zonal cleaning system includes a controlled air supply that has air tanks with outlet valves operating sequentially and cyclically for a predetermined amount of time. Upper rail assemblies are positioned relatively about and mounted to the upper portion of the sidewalls and each connects to one of the outlet valves. The upper rail assemblies have nozzles directionally oriented and the sidewall rail assemblies each have a fluid delivery line connecting to one of the outlet valves. One or more drop-down segments connects to the fluid delivery line, and each of the drop-down segments has a nozzle manifold with one or more nozzles. Activation of the controlled air supply expels air sequentially and cyclically through each of the upper rail assemblies and each of the sidewall rail assemblies.

A storage assembly comprising a tank having a cavity defined by a wall including a sealable port for receiving and storing a perishable organic fluid within the tank, the perishable organic fluid being chilled prior to transfer to the tank; a heat exchange structure at least partially located between an inner and outer wall surface of the wall, wherein prior to receiving the perishable organic fluid the heat exchange structure is configured to chill the cavity; and a sparging structure located within the tank, wherein the sparging structure is in fluid communication with a source of conditioning agent, wherein the sparging structure is configured to: transfer a first portion of the conditioning agent into the tank to purge the tank prior to receiving the perishable organic fluid; and sparge and pressurise the perishable organic fluid with a second portion of the conditioning agent after transfer and sealing within the tank.

A tank, such as a fermentation tank, includes a scraper blade assembly slideably coupled to a bottom surface of the tank. The scraper blade assembly includes a blade arranged to displace solids deposited on the bottom surface of the tank out through an aperture arranged flush with the bottom surface of the tank.

A storage container for storing quantities of acids and other volatile liquids is described having a recirculation system that can include a recirculation pump and a recirculation line that goes from a bottom end of the container toward a top end of the container, where the recirculation line has a plurality of pressure relief valves spaced along its length. The storage container may also include a leak detection system and a high level warning system.

Embodiments of the present invention include systems for storing large quantities of chemicals at a remote site. A controlled blending system balances the inflow of dry material and liquids into the blender based on a predetermined solid/fluid ratio. The blending system further balances the inflow and outflow of material from the blender.
