Abstract

This invention pertains to an insulation method for cryogenic liquids or gases where the tanks or pipes are made for transport or storage especially for LNG (Liquefied Natural Gas) where the tanks/pipes insulation (2, 3) consists of one, two or several layers of sheets with honeycomb core material. The honeycomb plates cavities are provided with expanded silicate that has good insulation like "Perlite". The container or the tank have a strongly build outer tank (4) and a flexible inner tank/layer (1) made of corrugated thin plate that can compensate temperature changes and is lying firmly against the honeycomb insulation (2, 3).

Description

Insulation method for cryogenic liquids and gases
This invention pertains to an insulation method for cryogenic liquids and gases for pipes and/or tanks made for transport or storage especially for LNG (Liquefied Nat- ural Gas) where the tanks/pipes insulation consists of one, two or several layers of sheets with honeycomb core material.
Known solutions Double walled heavy built tanks with vacuum, MLI (multilayer insulation) and/or perlite (in bulk) as insulation.
Their anomaly (disadvantages) High weight due to double walled heavily built tanks. Long cooling time of warm and empty tanks due to the inner tanks big mass and heavy weight that requires a lot of energy to cool it down to cryogenic temperatures. Expensive construction to manufacture. The connection of the inner tank is complicated and they are big heat bridges. The perlite (in bulk) is moving downwards and will be tight packed or compressed at the tanks lower part and thus lift up the inner tank which will damage the construction.
The innovations characteristics: The insulation situated on the inside of the tank, the insulation material consists of several layers of honeycomb paper provided/combined with expanded perlite (or similar silicates that has good insulation) in the honeycombs cavities. The paper honeycomb provided with expanded perlite insulation material, transfers the forces from the liquid/gas to the strongly build outer tank with minimum heat leakages (thermal conductivity). On the intimate surface of the honeycomb paper is a flexible tank/layer. The area between the outer and inner tank/layer will be pumped to vacuum in order to maximize the insulations thermal conductivity as well as to keep the flexible inner tank/layer on place. The innovations all characteristics appears in the patent claim. The advantages of the innovation
Lightweight construction.
Very high insulation ability that cryogenic liquids/gases needs.
Safe construction due to flexible inner tank that could flex without breaking in case of a crash or similar damages. The paper honeycomb provided with expanded per- lite insulation material, absorbs possible pressure chocks which could come from either outside or inside, and will soften the forces that are transferred from the inner tank to the outer tank.
The paper honeycomb provided with expanded perlite insulation material in several layers, gives a good protection against forces from the outside as well as damages ( crashes, shots ...) The outer tank does not need to be built with high tolerances due to the flexible inner tank that will correct all discrepancies in the size.
No heat bridges where heat could be transferred to the cryogenic content. Inexpensive and lightweight material. The insulation material is porous and hereby got the possibility to evacuate all the air in order to get vacuum everywhere in the material. The inner tank can have a lightweight and flexible construction because all forces are transferred directly threw the loadbearing insulation to the outer tank. Therefore can the inner tank have small mass (lightweight) and its cool down procedure of an empty and warm tank is extremely short which requires almost no energy/coolness. Due to the inner tanks small mass (lightweight) can regasification of cryogenic liquids be done directly in the tank with electrical heat resistors placed between the outer and inner tank.
The invention is described more detailed with reference to the enclosed drawing where:
Fig. 1 show the tanks cross-section and
Fig. 2 show the inner tanks corrugated pattern.
The tank or pipe is made for transport or storage especially for LNG (Liquefied Natural Gas) where the tanks/pipes insulation (2, 3) consists of one, two or several layers of sheets with honeycomb core material. The honeycomb plates cavities are provided with expanded silicate that has good insulation like "Perlite". The container or the tank have a strongly build outer tank (4) and a flexible inner tank/layer (1) made of corrugated thin plate that can compensate temperature changes and is lying firmly against the honeycomb insulation (2). The honeycomb core material could be paper that have high insulation ability and low temperature expansion coefficient. The space between the outer tank (4) and inner tank (1) can be vacuumed. Between the honeycomb sheets could even be inserted reflective layers in order to improve the insulation capacity. The inner tank could be provided with heating slings in order to regasify cryogenically liquids.
Variations of the invention. The shape of the tank can be cylindrical, quadratic or which shape needed. The size can be from small tanks to ISO container size or even up to shore terminal and tanker tank sizes. Pipes for cryogenic liquids can be made in accordance with this described system. This method can be used for other liquids/gases that have other temperatures than cryogenically. The paper honeycomb material provided with ex- panded perlite can be used alone as insulation material for other applications than cryogenic. Insulation capacity increase radically when the insulation material is in vacuum.
