摘要:
A liquefied gas storage tank and a manufacturing method therefor are disclosed. According to the present invention, in the liquefied gas storage tank, the material of a membrane, which is adjacent to a region in which a liquid dome is installed, is different from the material of a membrane, which is not adjacent thereto, such that the liquefied gas storage tank can effectively respond to the thermal deformation generated during the storage of liquefied gas.
摘要:
A support assembly mounted on the roof of a tank, comprising a support block (1), a base plate (4) between the support block (1) and the tank, and guiding brackets or rails (2) joined to a structure above the tank characterized in that each of the brackets or rails (2) comprise a face turned towards a cooperating face of the support block, the face of the bracket or rail and the cooperating face of the support block (1) are inclined at an angle, said angle depending on the width and height of the support (1).
摘要:
Apparatus is described for transferring cryogenic fluid from a first vessel (5) to a second vessel in an offshore environment. The apparatus comprises a partly submerged floating dock (1) with variable buoyancy means (14, 15) operable to alter the draught of the dock (1), enabling it to be lowered in the water and raised again to engage the dock (1) with the second vessel. A single point mooring system (3) is attached to the dock (1). At least one rigid cryogenic pipeline (6) is attached between the first vessel (5) and the dock (1) via flexible connection means (11, 19).
摘要:
The invention relates to a barrier layer arrangement for tank systems, comprising at least one layer made of a material that has anisotropic properties, wherein the anisotropic properties can be specifically adjusted by way of the design of the layer and/or the material parameters.
摘要:
A process and plant for the vaporization of liquefied natural gas (LNG) consist in obtaining electric energy during the vaporization operation by means of thermal exchange by transformation means of an energy source for obtaining electric power.
摘要:
A container is provided for storing pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123 DEG C (-190 DEG F) to about -62 DEG C (-80 DEG F). The container is constructed from an ultra-high strength, low alloy steel containing less than 9 wt.% nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73 DEG C (-100 DEG F).
摘要:
A method and apparatus for storing or transporting a hydrate slurry. The hydrate slurry is stored or transported at an elevated pressure up to 20 bar, but preferably up to 10 bar and at a temperature above that at which the liquid in the slurry solidifies or freezes.
