  • Patent number: 10078000
    Abstract: A method for determining a filling mass in a thermally insulated container for a cryogenically stored gas includes determining the filling mass using a known container volume and a calculated density of the gas content of the container. A temperature sensor is used for measuring a mixing temperature of liquid and gaseous phases, where the liquid phase is extracted via a first extraction supply line at the geodetically lowest point, and the gaseous phase is extracted via a second extraction supply line at the geodetically highest point. Downstream of the extraction points, after a convergence of the first and the second extraction supply line, the temperature sensor is placed where a complete and thorough mixing of the liquid and the gaseous phase of the gas from the first and second extraction supply line has already taken place.

    Abstract: Systems and methods for storing energy in gaseous form in submerged thin-walled tanks are secured to the ocean or lake floor but are open to the water at the tank bottoms and are configured to be filled with gas while submerged. A conduit operatively connected to the tanks provides flow from a surface source of an energy-containing gas to the tank interiors. Surface or subsurface pumping apparatus which may include piston-less pressure cylinders or have leveraged pistons provide a preselected flow rate of the energy-containing gas into the containment structure interior against a back pressure essentially equal to the static pressure of the body of water at the location of the tank to displace an equivalent volume of water through the open bottom. The conduit can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank using Aluminum activated with Galinstan.

  • Publication number: 20140007595
    Abstract: The invention relates to a process for the manufacture of a mixture of liquid nitrogen and liquid oxygen, the proportions of which are approximately those of liquid air, according to which: first, an amount AN2 of liquid nitrogen (10) is transferred (11) into a mixing tank (30); secondly, an amount AO2 of liquid oxygen (20) is transferred (21) into the mixing tank (30), the amounts AN2 and AO2 making it possible to reconstitute, in the mixing tank, a primary mixture within a given range of oxygen content; the mixing tank is kept on hold for a resting period which promotes the stabilization of the mixture formed, making it possible to obtain, on conclusion of this resting period, the desired mixture.

  • Patent number: 8590339
    Abstract: In method of providing uniformity of vapor and liquid phases in two or more streams derived from a mixed vapor and liquid stream (10), the mixed vapor and liquid stream (10) passes from a first heat exchanger (101) into a distribution vessel (12) via one or more inlets (14). The distribution vessel (12) has two or more outlets (16) connected to a second heat exchanger (102). The liquid part of the mixed stream (10) is allowed to collect in a first area (20) in the distribution vessel (12), and the vapor part of the mixed stream (10) is allowed to collect in a second area (30) of the distribution vessel (12), preferably above the first area (20). The liquid in the first area (20) passes into the outlets (16) via one or more liquid apertures (18) in each outlet (16) that communicate with the first area (20), and the vapor in the second area (30) passes into the outlets (16) via one or more vapor apertures (28) in each outlet (16) communicating with the second area (30).

  • Publication number: 20130192297
    Abstract: A small scale natural gas liquefaction plant is integrated with an LNG loading facility in which natural gas is liquefied using a multi-stage gas expansion cycle. LNG is then loaded onto an LNG truck or other LNG transport vehicle at the loading facility using a differential pressure control system that uses compressed boil off gas as a motive force to move the LNG from the LNG storage tank to the LNG truck so as to avoid the use of an LNG pump and associated equipment as well as to avoid venting of boil off vapors into the environment.
