Abstract

A tank for transport and/or storage of cryogenic gases especially for LNG (Liquefied Natural Gas) where the tank consists of an outer tank, loadbearing insulation and an inner tank that is made of a flexible plate/sheet material which have an expansion coefficient that does not affect the tanks construction even the temperature differences inside the tank could be over 200 C°. The plate/sheet material has tear drop patterns/corrugates of aluminium or another similar cold resistant metal.

Description

Tank for cryogenic gases
This invention pertains to a tank for transport and/or storage of cryogenic gases es- pecially for LNG (Liquefied Natural Gas) where the tank consists of an outer tank, loadbearing insulation and an inner tank that is made of a flexible plate/sheet material which have an expansion coefficient that does not affect the tanks construction even the temperature differences inside the tank could be over 200 C°.
Earlier known solutions are: a) Vacuum insulated double walled tanks manufactured of cold resistant metals. b) Moss-Rosenberg type spherical tanks made of cold resistant metal with the insulation on the outside.
c) Membrane tanks.
All the existing known tanks for cryogenic gases are expensive due to expensive materials and high workforce intensive solutions. a) Vacuum insulated double walled tanks are often pressure vessels which requires complicated manufacturing processes. This method suits better for small tanks b) Moss-Rosenberg tanks are spherical and requires therefore a lot of volume c) Membrane tanks are a fragile construction because the membrane tank is made of thin metal that does not sustain extreme stress that could arise when the tank is empty at hard vibrations and impacts. The effect of free liquid surfaces are extensile for this tank construction.
In the Finnish patent application 20135430 is described a tank which has much in common with this tank in this invention. The tank in the patent application
20135430 is based on several small cell tanks which creates the cell element.
In the Finnish patent application 20130357 is described an insulation method for cryogenic applications such as tanks and pipes for cryogenic gases where the insulation is on the inside of the tank/pipe. The tanks/pipes insulation have a leak proof layer made of carbon fibre, glass fibre, plastic, metal or similar leak proof material. Between the outer tank/pipe and the inner layer is the insulation made of honeycomb core material which keep the distance between the outer tank and inner layer. This new present invention is even an improvement of the earlier known techniques and still above named secret patent applications. The character for this invention is that the plate/sheet material is aluminium with tear drop patterns/corrugates.
The flexible plate/sheet material can be according to the unoriginality patent claim be corrugated tear drop pattern. It can also been expressed as plates milled with wave pattern or pressed round, oval, "salmiak figures" or quadratic hollows. The hollows could be filled with a suitable flexible material (Filler) as plastic or rug. Thus the inner tank construction can sustain higher pressure. The flexible plate/sheet material can also be polyimide or aramid. The inner tank will be pushed in to the outer tank that the insulation will be between both tanks (inner and outer). By vacuuming the space between the tanks will the flexible inner tank be placed tight to the insulation which can be for example a "honeycomb" construction as per the Finnish patent application 20130357. The whole tank construction becomes a strong, tight and well insulated, tank which is additionally inexpensive to manufacture.
The inner tank can also be provided with heating slings in order to heat up LNG to gas that can be taken out threw valve mechanism at the top of the tank. Between the outer tank and inner tank can also be installed heat reflective material like for example thin aluminium plate or folio. This will increase the insulation capacity.
