Abstract
A method of constructing a storage tank for liquefied gas at a very low temperature, under a pressure close to atmospheric pressure, which is distinguished in particular by the following characteristics, considered separately or in combination: a) consists of making a closed enclosure very mechanically resistant in order to provide a substantially continuous thermal insulation coating on the internal walls of said enclosure and to apply on said cover a flexible film, which constitutes an internal enclosure tight to the stored liquid and its steam; b) the aforementioned enclosure is made of reinforced concrete and this reinforced concrete is given a previous tension that is preserved for the lowest temperatures likely to occur during the exploitation of the deposit; c) the aforementioned thermal insulation coating is disposed on the inner walls of the enclosure in the form of successive layers of expanded plastic synthetic material, such as closed cell foams based on polyurethanes or epoxy resins, by in situ or projection molding; mainly by gun, in successive layers; d) a layer of metal or latticework made of elastic metal at the low temperatures considered, or a wide mesh fabric made of glass fibers, is inserted into the layers of thermal insulation, which are close to the stored cold liquid; to the fissures; e) according to a variant, the thermal insulator is arranged in the form of panels or prefabricated blocks; f) the aforementioned panels or blocks, the side walls and/or the ceiling are stuck or hooked by known methods; g) the flexible sealing sheet or film is made in the form of cloths, by gluing or calendering a set of two films of plastic material, between which a thin sheet of elastic metal is disposed at low temperatures, on a support fabric that remains flexible and capable of folding at the lowest temperatures considered; h) are carried out by means of the aforesaid cloths, which are joined together side by side and end to end, by bonding or local softening, for example (heat-sealing) large-area sheets that are hooked to annulled means on the walls of the tank lined with insulator forming, between two successive attachment points, some folds such that the waterproof envelope is not excessively stretched when low temperatures occur; i) they are glued or bonded by heat welding by iron and hot air, for example, the sheets are hooked to form a continuous watertight envelope, the metal sheets being continuously sealed by means of covering adhesion.
