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 method of storing and using natural gas (NG) in a vehicle includes selecting a vehicle having an NG tank for fueling an engine of the vehicle. The tank service pressure rating is 3600 psi (pounds per square inch) and an NG adsorbent is in the tank. A first quantity of NG is transferred into the tank from a first source having a first source pressure less than 725 psi. The adsorbent adsorbs a portion of the NG. After transferring the first quantity of NG, the engine is operated until NG is desorbed and consumed by the engine. NG is transferred into the tank from a second source to fill the tank to a second tank pressure of about 3600 psi. The adsorbent adsorbs some of the NG. After transferring the second quantity of the NG, the engine is operated until NG is desorbed and consumed by the engine.

A system that includes a marine vessel with a vaporizer skid disposed on the marine vessel. The vaporizer skid is configured to convert a liquid to a gas. The system further includes a first tank disposed on the marine vessel that is configured to store the liquid. The system further includes a plurality of header modules disposed on the marine vessel. The plurality of header modules form a piping network that provide a first flow path from the first tank to the vaporizer skid and a second flow path from the vaporizer skid to a connective interface. The connective interface is configured to provide a flow path from at least one of the plurality of header modules to an end-user system.

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 disclosure is directed toward a method for storing methane. The method for storing methane comprises several steps. A dissolving fluid comprising water is injected into a salt formation to produce a brine and a salt cavern within the salt formation. The brine is then removed from the salt cavern. A sorbent is then placed within the salt cavern before methane is injected into the salt cavern.

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.
