摘要:
The invention relates to a tank comprising a container with an opening and a cover, a flexible casing lying against the interior and exterior of the container. This allows increased resistance to the penetration of sharp objects, liquid and gaseous gases can be used interchangeably and various gas types with a fossil-type and biological-type consistency can be mixed and also heated and cooled in the tank. The invention relates to tanks (1) and staged tanks of the preceding claims, characterised in that in addition to LNG, said tanks can store biological methane gas.

A new and improved apparatus for detecting cracks in the heat-insulating liner of a container for cold liquids, wherein a plurality of breakable or frangible electrical conductors and a barrier means having a woven mat of glass-fiber material are incorporated in the heat-insulating material and detector means is connected with the electrical conductors to detect breaks in the electrical conductors caused by cracks in the heat-insulating material attaining a critical length. The frangible electrical conductors may be frangible wires or stripes of conducting paint.
摘要:
Thermally insulated container or tank wall construction for cryogenic fluids such as liquid natural gas (LNG) comprising at least two layers of an insulation material, preferably a fiberglass reinforced urethane foam, having an inner liner, preferably in the form of an aluminum foil-fiberglass cloth combination, in contact with the cryogenic fluid, the inner liner being perforated to permit rapid venting, and a thermal stabilizing barrier or liner between the layers of insulation, the stabilizing barrier also preferably being formed of a combination of fiberglass cloth with a layer of aluminum foil to reduce permeability. The two liners are bonded to the individual layers of insulation and the insulation is in turn bonded to the container or tank wall by a suitable adhesive such as a polyurethane adhesive.In the design of such system, the low permeability thermal stabilization barrier is placed a distance from the cold insulation face adjacent the inner liner equal to or greater than a distance at which boiling will be established adjacent the thermal stabilizing barrier, thereby building up a thin gas layer adjacent to such barrier and preventing liquid from contacting and penetrating the stabilizing barrier.
摘要:
Insulation panels are for use in providing a gas insulation layer between a surface and a liquid having a low boiling temperature. The insulation comprises a cellular or honeycomb core having a plurality of discrete cells enclosed by a capillary cover with capillary openings communicating with each cell. The honeycomb core is tensioned and also is shaped to an arcuate or concave configuration before the capillary cover is adhesively secured thereto. The adhesive forms a smoothly radiused joint between the core walls and the capillary cover with the adhesive being feathered on the cover and the walls immediately adjacent the joint. Vacuum is applied to each cell to form a dimple in the capillary cover and the capillary openings are then formed in the cover. A filler material may be placed in each cell and a backing sheet applied to the core to maintain the filler in the cells and facilitate assembly of the panel to the surface to be insulated. Each cell may be tested individually by applying a vacuum to the capillary opening associated with that cell and, if a leak between the capillary cover and the core is detected, the portion of the cover over that cell may be removed and a predimpled cover patch secured over the cell.
摘要:
Capillary insulation for low temperature liquids in which a cellular structure defines a plurality of discrete cells enclosed by a capillary cover with capillary openings communicating with each cell. The cell walls and the cover are designed to minimize the effects of strains imposed thereon by providing an excess of material both in the walls and the cover thereby permitting them to deflect without adversely affecting operation of the insulation. The cell walls are formed in an S-shaped configuration and the cover is dimpled to provide the desired excess material. The capillary openings are reinforced by a toroidal rib extending around each opening.

A liquefied gas e.g., methane storage tank 14, Fig. 1, is lined with a plurality of downwardly inclined spaced superposed louvres 36 each overlapping the upper end portion of the adjacent lower louvre so as to provide vapour pockets 38 adjacent the vertical wall 16 of the tank which may be of circular or rectangular cross-section having its bottom 18 lined with cork or aerogel heat insulating material 40 in which are embedded metal pans 20 having upturned rims 28 extending between the lowermost louvres 36. Thermal expansion of the louvres is accommodated by a plurality of radially extending circumferentially spaced corrugations. In a modification the lower ends of louvres 36 Fig. 14 have skirts 110 which assisted by baffles 118 serve to support heat insulation material 112 held in porous bags 114.

The disclosure relates to a sealed and thermally insulating tank for storing a fluid, said sealed tank comprising an outer support structure, a thermal insulating barrier retained on the support structure, and a sealing barrier supported by the thermal insulating barrier. In one embodiment, the thermal insulating barrier comprises a corner structure positioned at an intersection between a first and a second wall of the support structure, the corner structure comprising a first and a second insulating panel, each having an outer surface positioned facing the support structure, an inner surface provided with a member for securing the sealing membrane, and lateral edges, the first panel having an outer surface resting against the first wall of the support structure and a lateral edge resting against the second wall of the support structure, the second panel having an outer surface resting against the second wall of the support structure and a lateral edge resting against the outer surface of the first panel.
摘要:
The present invention is related to a reinforcing member for a membrane for improving the pressure-withstanding property of the membrane having corrugations, and a membrane assembly having the reinforcing member and a method of constructing the membrane assembly. By providing a reinforcing member for a membrane having corrugations and installed in an insulating structural member of an LNG cargo, the present invention can prevent the collapse of the corrugation and attenuate shocks against a same load without increasing the facial rigidity of the corrugation, and improve the insulating property by forming an additional insulating layer.
