A solvent storage and depressurization system is described. The system allows a volume of solvent to be stored and used at low pressure, thereby providing safety benefits and regulatory simplicity. The system includes an external expansion tank that is located outside of an extraction facility and that contains a solvent. The system also includes an internal storage tank that is located inside of the extraction facility and that provides a solvent supply to a solvent user, such as a phytochemical extraction system. The external and internal tanks are separated and connected via a duplex manifold. The manifold allows gas below a first pressure level to pass from the external expansion tank to the internal storage tank, and allows gas above a second pressure level to pass from the internal storage tank back to the external expansion tank, wherein the second pressure level is greater than the first pressure level.

A fuel management method for long term stationary truck use is provided. This method includes a truck with at least a first saddle tank or a second saddle tank integral to the truck. Each saddle tank has a fuel level sensor to measure the fuel level. A fuel trailer provides supplemental fuel, and a fuel pump downstream of the fuel trailer and upstream of the truck pressurizes the fuel from the fuel trailer. The method includes supplying fuel to local users from saddle tanks, activating the fuel pump when the fuel level of both the saddle tanks is less than a first predetermined threshold, thereby transferring fuel from the fuel trailer to the first saddle tank and the second saddle tank, deactivating the fuel pump when the fuel level of either the saddle tanks is greater than a second predetermined threshold.

A liquefied gas storage tank according to an embodiment of the present invention may comprise: a tank unit in which liquefied gas is stored; an inner box unit disposed inside the tank unit and installed at the bottom portion of the tank unit; and a pump unit that has an inlet pipe part formed to pass through a lower wall portion of the inner box unit and communicate with the inside of the inner box unit, and suctions the liquefied gas stored in the tank unit through the inlet pipe part, thereby supplying the liquefied gas to the outside.

Described are storage and dispensing systems and related methods for the selective dispensing germane (GeH.sub.4) as a reagent gas from a vessel in which the germane is held in sorptive relationship to a solid adsorbent medium that includes zeolitic imidazolate framework.

The invention can include a device and method for distributing a fluid in an industrial facility that comprises a fluid distribution pipe, a discharge pipe, a distribution valve that is positioned on the distribution pipe and controlling the distribution of fluid between an upstream area and a downstream area, a discharge valve positioned on the discharge pipe, and measuring means for measuring, in real time, a characteristic parameter of the distribution of the fluid within one of the pipes. A module is also included for calculating a sliding threshold value of the characteristic parameter and means configured to control the partial gradual opening or closing of the discharge valve depending on the result of the comparison of said sliding threshold value with an instantaneous value of the characteristic parameter, in order to improve reliability of the industrial facility.
