A cryogenic full containment storage tank for realizing a low-liquid-level material extraction function by using a pump column, comprising an inner tank, an outer tank, a pump column, a submersible pump and a material pre-extraction device; wherein the material pre-extraction device comprises a cofferdam, a Venturi mixer, a backflow pipe, a return control valve, a lead-out pipeline and a liquid level detection system. The cryogenic full containment storage tank can make use of a low-temperature medium flowing back from the pump column to extract the low liquid level material outside the cofferdam into the cofferdam to form a local high liquid level and maintain the normal operation of the submersible pump.

A controllable gas-storage-form gas supply tube device includes a three way tube having a first opening, a second opening and a third opening; an electric control valve device installed in the three way tube for controlling connections of the three openings; an input tube, a close form air storage tube and a draining tube are connected to the first, second and third openings, respectively. When the electric control valve device is at a first position, the third opening is closed and the first and second openings are communicated so that gas from the input tube flows to the close form air storage tube and is stored therein. When the electric control valve device is at a second position, the first opening is closed, and the second and third openings are communicated so that gas in the close form air storage tube flow to the draining tube.

A portable, modular fueling system for the storage, dispensing and offloading of fuel from a rail vehicle to one or more other fuel storage vessels is disclosed. The system module is self-contained on an ISO standardized intermodal platform. The module is capable of being in fluid communication with a plurality of modular storage vessels, either rail-bound or wayside, such as for delivering fuel to a fuel tender or a locomotive. Electrical power, equipment storage, lighting, and compressed air may be located on the intermodal rail car or in a support module, such as either ground-based or rail-mobile. Alternatively, the platform can be mounted to a trailer chassis, or affixed to a land-based foundation matching the standardized intermodal container footprint. Control of the fuel system is provided by automatic means with manual override.
