A heat exchanger which is used primarily in oil and gas operations to heat tanks of liquids, such as drilling mud, water, heavy oil or other such fluids from freezing or becoming too viscous to pump.

When products to be shipped are temperature-sensitive, it is necessary to maintain a substantially uniform and constant temperature to avoid spoilage. As a result, thermal shields are often placed on top of the products. Many designs for thermal shields have been considered in the past but improvements are still desired. Accordingly, there is provided a multilayer thermal shield (100) comprising a thermally conductive layer (108), and at least one heat exchange fluid circuit (120) coupled to a first surface of the thermally conductive layer, the at least one heat exchange fluid circuit comprising at least one inlet (124) configured to permit the ingress of heat exchange fluid. The thermal shield further comprises an outer insulation layer (104) connected to a first surface of the thermally conductive layer (108) and comprising grooves designed to receive the heat exchange fluid circuit. The thermal shield further comprises an inner insulation layer (110) connected to a second surface of the thermally conductive layer (108).

A temperature controlled container comprises exterior wall structure, interior wall structure positioned within the exterior wall structure, the interior wall structure at least partially defining an interior space configured to hold one or more products for shipping, and a chamber defined between the interior and exterior wall structure, the chamber configured to retain thermal storage medium to provide a thermally insulative layer at least partially protecting the interior space.

A system for transporting fluid cargo within a shipping container, the system comprising an open topped box having side walls and end walls and a flexible membrane which either independently or in combination with the box contains the fluid cargo. The box supports the portion of the cargo within the box and is designed to flex and absorb at least part of the horizontal forces generated within the cargo during its transportation thus preventing overloading of the walls of the surrounding container. The membrane may be a bladder which completely encloses the cargo and is disposed partially within the box to contain the cargo independently of the box. The box may have a floor pan which can seal the box against leakage of any cargo.

A circulation chamber for a cargo container comprises a cargo container extension including a housing, a cargo container aperture, and an interior volume; the cargo container extension is structured and dimensioned to be attached to an opening of the cargo container, thereby placing the interior volume in fluid communication with an interior of the cargo container. The housing, cargo container aperture, and interior volume may be cooperatively structured and dimensioned to allow at least a portion of the cargo container to be disposed and projected through the cargo container aperture, and furthermore, allow, at least partially, the opening of a door of the cargo container while the circulation chamber is attached to the cargo container.

A storage and transport system for sodium hypochlorite pentahydrate (solid bleach) is provided. The system includes a container configured to receive and store crystalline solid bleach that includes of at least forty percent sodium hypochlorite, and to retain decomposition components from crystalline solid bleach stored in the container. The container includes a containment wall at least partially surrounding an interior containment space configured to receive solid bleach therein. A passage extends from exterior the container to the interior containment space. The passage is configured for solid bleach to pass therethrough. A liner is located at an interior surface of the containment wall. The liner is substantially non-reactive with solid bleach and, without leakage, capable of retaining within the containment space: (a) solid bleach, (b) decomposition components of solid bleach and (c) liquid bleach formed when dissolving water is added to solid bleach within the containment space.

The invention relates to a thermally insulated transport container with a housing for forming a space for goods, with walls and a thermal insulation abutting the walls as well as a wall structure of such a container. In particular, the invention relates to such a container as an air cargo container. According to the invention, sandwich plastic plates are provided as walls, with a honeycomb core welded on both sides to one covering ply, respectively, the honeycomb core and the covering plies consisting of a thermoplastic material, preferably PP. In this case, the walls are, in particular, a thermoplastic sandwich panel, consisting substantially of a PP (polypropylene) honeycomb core and PP covering layers, in particular glass-fiber reinforced, which are, with regard to the materials, homogenously connected to each other by thermally fused connection. Such plates are offered, for example, by Wihag Composites GmbH & Co. KG under the trademark MonoPan®, which are preferred in this case. The use of thermoplastic material makes it possible for adjacent sandwich plastic plates to be attached to each other by welding, particularly in the region of the edges. In particular, it is thus possible to produce largely frameless and thus lighter transport containers.

A mobile polystyrene foam waste recycling method and system are disclosed. The system includes a mobile housing or mobile container that houses a polystyrene foam densifying machine. The foam densifying machine reduces the size of Expanded Polystyrene (EPS) and PS polystyrene material into a marketable product. The mobile container includes secure access doors, electrical connections, lighting, exhaust fans, and storage bins for EPS waste. The waste recycling system provides a mobile outdoor or indoor recycling facility and collection center where EPS/PS may be recycled instead of being sent to a landfill.
