Abstract:
The invention relates to a vaporisation device (4) for the cooling of a liquefied gas, said vaporisation device (1) comprising: a vaporisation chamber (14) disposed inside the inner space of a container (2, 19) that is intended to be filled with liquefied gas (3), the vaporisation chamber (14) comprising heat exchange walls (6) allowing the exchange of heat between an inner space inside the vaporisation chamber (14) and a liquefied gas (3) present in the inner space of the container (2, 19); an inlet circuit (5) comprising an intake that opens into the inner space of the container (2, 19) in order to remove a flow of liquefied gas in liquid phase from the container (2, 19) and a head loss member (13) that opens into the inner space of the vaporisation chamber (14) in order to expand the removed gas flow; and an outlet circuit (7) arranged to discharge the removed gas flow in gaseous phase from the vaporisation chamber (14) into a vapour-phase gas usage circuit (8), said outlet circuit (7) comprising a vacuum pump (9) that draws the gas flow into the vaporisation chamber (14), drives same towards the vapour-phase gas usage circuit (8) and maintains an absolute pressure below atmospheric pressure inside the vaporisation chamber (14).
Abstract:
Die vorliegende Erfindung schlägt einen Druckbehälter für eine Innen- oder Außendruckbeanspruchung, insbesondere für ein U-Boot, vor mit einer Wandung, die einen Inliner und ein Fasern aufweisendes Faserlagenpaket umfasst, wobei der Inliner zumindest teilweise vom Faserlagenpaket ummantelt ist, wobei das Faserlagenpaket eine erste Schicht und eine zweite Schicht aufweist, wobei in einem Teilbereich in der ersten Schicht Fasern entlang einer ersten Faserrichtung um den Inliner verlaufen und in der zweiten Schicht Fasern entlang einer zweiten Faserrichtung verlaufen, wobei der Inliner zur Stabilisierung des Druckbehälters einen Bereich erhöhter Materialstärke aufweist.
Abstract:
Described is a cylinder (1) for high pressure compressed fluids comprising a first hollow body (2) having an opening (2a) towards the outside (100) forming with the relative internal cavity a first housing space (2b) for a compressed fluid; at least one second hollow body (3) having an opening (3a) towards the outside (100) and forming with the relative internal cavity a second housing space (3b) for a compressed fluid which is separate and different from the first housing space (2b). The second hollow body (3) is housed inside the first hollow body (2) in such a way as to define a first housing chamber (6) and a second housing chamber (7). The first and second chambers (6, 7) have, respectively, an opening (2a, 3a) towards the outside (100) at the head end (4) of the cylinder (1) and at least the first or the second hollow body (2, 3) has at a bottom end (5) a bottom opening ("C") which is normally closed.
Abstract:
A storage system for compressed natural gas which includes at least one storage vessel for storing CNG and a cooling station wherein the storage vessel is connected to the cooling station so that CNG may be stored in the storage vessel after had been passing through the cooling station and once the stored gas conditions fall out a set range, it is cooled in the cooling station, and returned to the storage vessel, wherein the storage vessel is thermally insulated from the exterior thereof thanks to the composite materials and especially glass-reinforced polymers whose pressure vessels are made.
Abstract:
This invention is directed to a method of decreasing the rate of escape a gas from a breached containment system by introducing into the containment system a plurality of objects that create a tortuous path for the gas to get to the point of breach thereby substantially reducing the degree of damage done by the breach.
