Abstract:
A method of utilizing a divided pressure vessel in a processing system employing a carbon dioxide based solvent includes transferring a first carbon dioxide based treating solution from a first liquid chamber in a divided pressure vessel having a plurality of liquid chambers to a processing vessel, returning the first treating solution from the processing vessel to the divided pressure vessel, transferring a second carbon dioxide based treating solution having a composition different from the first treating solution from a second liquid chamber in the divided pressure vessel to a processing vessel, and returning the second treating solution from the processing vessel to the divided pressure vessel. A divided pressure vessel may allow multiple solvent baths each having a different chemical composition to be stored and/or processed in a single pressure vessel while maintaining the different chemical compositions of the multiple solvent baths. Thus, such divided pressure vessels may provide the improved operational efficiency of a carbon dioxide based system having multiple solvent baths while decreasing the capital costs that may be associated with such systems.
Abstract:
A storage container for cryogenic liquids has an outer container and at least one inner container, an insulation space being situated between the outer container and the inner container or containers. The outer container and/or the inner container have devices for strengthening the container walls. The devices for strengthening the container wall of the outer container and/or of the inner container are constructed as at least one web arranged on the container wall of the outer container and/or of the inner container and/or as at least one supporting plate adapted essentially to the cross-section of the inner container.
Abstract:
A pressure vessel for holding a pressurized fluid such as compressed natural gas ("CNG") includes two end cells and zero or more interior cells. The cell geometry ensures that the cells meet one another at tangential circular surfaces, thereby reducing the tendency of adjacent cells to peel apart. A web secured about the cells includes two sheets that are tangent to the cells. Unused volumes between the cells and the web contain wedges of foam or rubber. A valve provides fluid communication between the interior of the pressure vessel and a pressurized fluid line. The filled weight of one pressure vessel does not exceed the filled weight of a conventional gasoline tank that occupies substantially the same space as the pressure vessel. The pressure vessel may be configured with exterior recesses for engaging conventional gasoline tank straps.
Abstract:
The present invention relates to a pressure vessel (1) comprising at least one intermediate part (4) with an end wall (2, 3) connected to each of its ends (1A, 1B), and longitudinal internally reinforcing walls dividing said intermediate part (4) into fluid-accommodating compartments. The intermediate part (4) with enclosed reinforcing walls consists of an extruded profile with reinforcement and an intermediate part casing integrated with one another, and the respective end walls (2, 3) are capable of attachment by fastening means to the end of the respective intermediate part so that forces arising inside the vessel as a result of the internal overpressure against the respective end wall (2, 3) are distributed so that they act axially in the intermediate part (4), both in its outer casing and internal reinforcement.The invention also relates to a method for the manufacture of the pressure vessel in accordance with the invention.
Abstract:
A cryogenic fuel tank of a cylindrical design having toroidal surface ends, is suspended in aircraft structure through a central front mount member; and the rear tank is supported by rod elements which extend from a mounting ring about the tank, to mount points rearwardly within the interior of the fuselage. The central front mount member has baffles attached thereto, so as to prevent undue sloshing of the liquid within the tank. The front end of the tank suspension absorbs radial and axial loads, but no bending moments; and the aft linkage suspension arrangement takes primarily radical and torsional loads. Also the aft suspension provides for unrestrained axial and radial contraction and expansion of the outer shell of the tank.
Abstract:
A container for a liquefied fuel gas, constructed to be prevented from being filled with excess liquefied fuel gas which would otherwise lead to unexpected blasting due to thermal expansion of the stored liquefied fuel gas, the container having main and auxiliary compartments which are completely isolated when the liquefied fuel gas is fed into the main compartment and which are permitted to communicate with each other so as to provide an unoccupied space in the main compartment.

929,609. Soil stabilisation. CONCH INTERNATIONAL METHANE Ltd. Feb. 12, 1962, No. 5325/62. Class 68 (1). [Also in Group XXVIII] Freezing of the water-bearing earth surrounding a plurality of shafts 2 intended for stoning liquefied gases (see Group XXVIII) is effected by filling the shafts with water or drilling mud, introducing double pipes, and passing refrigerant therethrough until a sufficient layer of frozen earth is obtained and finally passing steam through the double pipes to thaw any ice formed in the liquid with which the shafts are filled. In a modification the shafts are filled with refrigerant which is afterwards withdrawn. Each shaft is lined with concrete, aluminium or steel. Specification 894,762 is referred to.
