wherein the sealing membrane includes corrugated metal plates comprising a first series of parallel corrugations, extending along a direction x and a second series of parallel corrugations extending along a direction y, the direction x being a direction of greater slope, wherein the peripheral walls (1) comprise filling elements with pressure loss, which are disposed in the corrugations of the first series of corrugations so as to form a belt (16) of filling elements extending all round the tank (71), the belt being formed of at least one obstruction part (17) and of at least one discontinuation part (18), the belt including at most one discontinuation part (18) per peripheral wall (1).

A method for manufacturing a high-pressure tank including a reinforcing layer in which rims of both ends of a tubular member and rims of a pair of dome members are joined to overlap each other in a radial direction includes producing the dome members and producing the tubular member. The producing of the dome members includes producing a wound body on a mandrel, curing a resin contained in the wound body, shaving the wound body after the resin is cured to reduce, toward a split line, thicknesses of the rims of the dome members to be obtained by splitting the wound body, splitting the shaved wound body into the dome members by cutting the wound body along the split line, and demolding the dome members from the mandrel.

An integral side slope structure of a soil-covered tank, includes a tank body, connecting pieces, and reinforcing frameworks. The exterior of the tank body is completely covered with soil, and a side slope is formed after the tank body is covered with the soil; each connecting piece is composed of ribs which are in cross connection to each other; the connecting pieces are connected to the outer wall of the tank body and are laid inside the side slope in the horizontal direction; a single-layer connecting net is formed after a single layer of the connecting pieces is connected to the tank body; a plurality of layers of the connecting pieces are arranged at intervals in the vertical direction; the tank body and the side slope are connected by the multi-layer connecting net to form an integral structure; the reinforcing frameworks are arranged along the side slope.

Regasification systems and processes for converting liquid natural gas (LNG) from a liquid into a gaseous state are described. The process includes a closed-loop system that uses geothermal wells as a heat source. A warming fluid circulates through the closed-loop system coupled with a geothermal well and a LNG heat exchanger. The warming fluid is heated as it passes through the geothermal well and cooled as it passes through the LNG heat exchanger, thus heating and gasifying the LNG. The cooled warming fluid then returns to the geothermal well. The closed-loop system minimizing environmental impact by eliminating the need to discharge the warming fluid.

A pressure vessel assembly includes a plurality of lobes, each lobe having at least one vertically arranged interior wall, the lobes positioned in a side by side arrangement such that a first interior wall of a first lobe is positioned adjacent a second interior wall of a second lobe, the first interior wall having a first wall top and bottom side, the second interior wall having a second wall top and bottom side, the first wall top side joined to the second wall top side and the first wall bottom side joined to the second wall bottom side. Also included are first and second end wall surfaces of each of the plurality of lobes. Further included is a plurality of end caps, each of the end caps joined to the end wall surfaces of the lobes, each of the end caps joined to at least one adjacent end cap.

Provided is a pressure vessel having an outer layer with an improved gas barrier property, a lightweight liner with an excellent gas barrier property, and a novel method for manufacturing a pressure vessel. The pressure vessel contains a liner and an outer layer of the liner, wherein the outer layer is configured by a composite material that contains a continuous fiber and a polyamide resin impregnated into the continuous fiber; the polyamide resin contains a structural unit derived from diamine and a structural unit derived from dicarboxylic acid; and 50 mol % or more of the structural unit derived from diamine is derived from xylylenediamine.

The invention is related to a storage vessel (1) comprising a shaped body (3) of a porous solid, wherein the storage vessel (1) comprises a wall (5) with a section (7) comprising at least one inlet (9), wherein the storage vessel (1) has a central axis (11) and the central axis (11) is a longitudinal axis of the storage vessel (1) and/or perpendicular to a cross-sectional area of the at least one inlet (9), wherein the shaped body (3) covers at least 85% of an inner volume (13) of the storage vessel (1) and the shaped body (3) comprises an opening (19) in an axial direction (17), axial referring to the central axis (11) of the storage vessel (1), wherein the opening (19) extends from a first end (21) of the shaped body (3) to an opposing second end (23) of the shaped body (3) and wherein the storage vessel (1) comprises exactly one shaped body (3), which is formed in one piece. The invention is further related to a shaped body and use of the shaped body.

A pressure vessel has a first end with a first boss, the first boss having a first outer surface. The vessel includes a liner having a second outer surface, a shell disposed over the second outer surface, and a first vent. The first vent is formed onto at least a portion of the first outer surface and at least a portion of the second outer surface. The first vent includes a texture that provides a higher rate of gas flow through the first vent than through a portion of an interface of the liner and shell lacking the texture.
