A system and method for duplicating a flammable gas (SDFG) that utilizes a specially engineered liquid in combination with a purpose-built container to duplicate the flammable gas is disclosed. There are three methods for the production of an engineered liquid for use in the system. In less than one hour, a single unit of any flammable or hydrocarbon gas will yield up to at least double the quantity of the same gas back.

An adsorbed natural gas storing tank is provided. The adsorbed natural gas storing tank includes a tank body that has an upper plate and a lower plate coupled to define an inner space provided with an adsorbent material. The tank body includes an opening that extends through the upper and lower plates. A central plate is inserted in the opening to seal one side of the tank body. Additionally, the central plate has a plurality of discharge apertures formed along a circumferential wall thereof to discharge natural gas reacted with the adsorbent material and has a mounting region therein. A filter assembly is inserted in the mounting region, is fastened to the central plate, filters natural gas passing through the discharge apertures, and is equipped with a control valve for adjusting natural gas discharge.

A structural component having an internal support structure extending between outer wall portions of the component with one or more compartments included within the support structure. The support structure has support members including internal walls positioned between and/or defined by the compartments. At least one support member connects between the outer wall portions of the component to enhance the structural integrity of the component. The structural component, including the internal support, are cast from a molten material, and in some cases the support members of the internal support structure are formed with a rectilinear configuration. In some cases the cast structural component is a container and the one or more compartments are configured to store a fluid, such as a gas or a liquid. One or more preforms can be used to form a container and may be retained or eliminated from the container after casting.

Systems and methods for heat exchange during gas adsorption and desorption cycling, one method including removing heat from an adsorbent material during gas adsorption to the adsorbent material; storing the removed heat for later use during desorption of gas from the adsorbent material; heating the adsorbent material during desorption of gas from the adsorbent material using at least a portion of the removed heat; and recycling heat during the step of heating to prepare a working fluid for the step of removing heat via temperature reduction of the working fluid.

The present invention provides a porous coordination polymer having high ability of storing a gas. The porous coordination polymer according to the present invention comprises zinc cluster ions and one kind of tricarboxylic acid ions selected from the group consisting of the following chemical formula (I), the following chemical formula (II), and the following chemical formula (III); ##STR00001## where X represents a natural number of not less than 1 and not more than 3, wherein the tricarboxylic acid ions are bound to the zinc cluster ions as terdentate ligands.

This invention provides a means of loading, processing and conditioning raw production gas, production of CGL, storage, transport, and delivery of pipeline quality natural gas or fractionated products to market. The CGL transport vessel utilizes a pipe based containment system to hold more densely packed constituents of natural gas held within a light hydrocarbon solvent than it is possible to attain for natural gas alone under such conditions. The containment system is supported by process systems for loading and transporting the natural gas as a liquid and unloading the CGL from the containment system and then offloading it in the gaseous state. The system can also be utilized for the selective storage and transport of NGLs to provide a total service package for the movement of natural gas and associated gas production. The mode of storage is suited for both marine and land transportation and configured in modular form to suit a particular application and/or scale of operation.

The present disclosure relates to improved processes for the preparation of metal hydrides. The present disclosure also relates to metal hydrides, e.g., metal hydrides prepared by the processes described herein, that exhibit enhanced hydrogen storage capacity when used as hydrogen storage systems.

Systems and methods to create and store a liquid phase mix of natural gas absorbed in light-hydrocarbon solvents under temperatures and pressures that facilitate improved volumetric ratios of the stored natural gas as compared to CNG and PLNG at the same temperatures and pressures of less than 80 to about 120 F. and about 300 psig to about 900 psig. Preferred solvents include ethane, propane and butane, and natural gas liquid (NGL) and liquid pressurized gas (LPG) solvents. Systems and methods for receiving raw production or semi-conditioned natural gas, conditioning the gas, producing a liquid phase mix of natural gas absorbed in a light-hydrocarbon solvent, and transporting the mix to a market where pipeline quality gas or fractionated products are delivered in a manner utilizing less energy than CNG, PLNG or LNG systems with better cargo-mass to containment-mass ratio for the natural gas component than CNG systems.

In at least some implementations, a device for filling a fuel gas storage tank includes a nozzle body having an inflow passage arranged to communicate a fuel gas source with the storage tank and an outflow passage arranged to receive an outflow of fuel gas from the storage tank. The inflow passage may be communicated with an inlet passage to admit fuel gas into the storage tank and the outflow passage may be communicated with an outlet passage through which fuel gas exits the storage tank. The outflow passage may be communicated with a downstream component for treatment of the outflow fuel gas, such as filtering, drying, and/or cooling. The outflow fuel gas may be rerouted into the fuel gas storage tank through the inflow passage and inlet passage, if desired. The disclosure also relates to a fitting for a storage tank and a method of filling a storage tank.
