Description
DESCRIPTION
INSULATED VESSEL SUPPORT SYSTEM Technical Field
The invention relates to thermally insulated vessel support systems.
The invention particularly relates to thermally insulated vessel support systems that are positioned between vessels placed in one another in cryogenic vessel systems and that enable fixing the inner pressure vessel to the outer vessel.
Background of the Invention Cryogenic vessels are vessels that enable storing and transporting gases such as nitrogen, natural gas, oxygen etc. in liquid form at very low temperatures like -196Ό and pressures higher than 0,5 bar. Cryogenic vessel consists of two vessels that are placed in one another. Inner vessel is made of stainless steel, whereas outer jacket (or vessel) is made of carbon steel. The space between inner vessel and outer jacket is called annular space. Air in the annular space is vacuumed and isolating material is used to reduce heat transfer further.
In the current state of the art, cryogenic vessels are usually supported at the bottom side of the vessel by means of radial supports in order to provide higher mechanical rigidity. Supports are located at least at 4 points. Increasing the number of supports enables fixing the inner vessel securely to the outer jacket but it increases the heat transfer area. The amount of heat transfer from external environment to the inner vessel increases as does the heat transfer area.
Thermal insulation affects the performance of cryogenic vessels directly. When the average environment temperature is +20qC and the temperatur e of the cryogenic fluid is around -196Ό, the temperature difference between two environments is 2'\ 6qC. This temperature difference causes large amounts of heat transfer from environment to the cryogenic vessel resulting in heating of the cryogenic fluid inside the vessel. Heated cryogenic fluid enters gas phase and the pressure of the inner vessel increases. For safety purposes, gas creating this excess pressure is relieved through the safety valves. Therefore, fluid that should be stored in the cryogenic vessel is vented to the atmosphere, causing economical loss.
US Patent Document No. US4496073 titled 'Cryogenic vessel support system' can be given as an example of cryogenic vessel support systems. The system employs supports, whose disadvantages are discussed, at the upper and lower region of the inner vessel. Consequently, the need for thermally insulated vessel support systems that are positioned between vessels placed in one another in cryogenic vessel systems and that enable fixing the inner pressure vessel to the outer vessel as well as the inadequacy of existing solutions have necessitated making a development in the relevant technical field. Object of the Invention
The present invention relates to support systems that meet the above-mentioned needs, eliminate the possible disadvantages and provide some additional advantages. The main object of the support system according to the invention is to fix the inner vessel to the outer jacket in a thermally insulated manner in two-layer vessel systems and particularly in cryogenic vessel systems. The support positioned in between two vessels in order to fix the inner vessel to the outer jacket should also be thermally insulated. Placing a thermally insulated support inside the annular space that has been vacuumed and thermally insulated directly increases the performance of the cryogenic vessel. Support system enables fixing the inner vessel to the outer jacket from two points on the heads of the vessel. Body of the support system is made of fiberglass composite material and it permits minimum amount of heat transfer between two vessels since it has a low heat transfer coefficient. Mentioned fiberglass is preferably G10 and/or an equivalent composite (FR-4 etc.). Thermal conductivity of stainless steel is 15,1 W/m*K, whereas thermal conductivity of the composite G10 is 0,2 W/m*K. Furthermore, while at least four supports were used in state of the art, the developed support system employs two supports which are smaller compared to the previous ones. Therefore, supports keep the heat transfer at minimum levels. Since low heat transfer does not lead to heating of the cryogenic fluid in the inner vessel, the amount of cryogenic fluid that enters gas phase is very low. Accordingly, inner vessel pressure has a lower increase and a much more lower amount of gas is discharged through the safety valves. This way, the fluid that has to be stored inside the cryogenic vessel is not relieved to the atmosphere, preventing economical losses. With the developed support system, evaporation rate of a LNG cryogenic vessel operating at 8 bar pressure has been found to be 0,1 % daily. This value is approximately 0,5% for other equivalent vessels. Moreover, the thermal power transfer value of 175 W or higher in existing techniques has been reduced to 35 W thanks to the developed support system. Therefore, economical losses and pressure increase are significantly reduced.
Another object of the invention is to provide high strength between the inner vessel and outer jacket. Support ends are fastened on the composite body on multiple points by means of socket head fasteners made of stainless steel. Therefore, high strength is obtained by means of fasteners even if the body made of composite material cannot be welded. Meanwhile, the developed support system has two different types called fixed support and sliding support in order to be compatible with different types of cryogenic vessels. Fixed support is used for fixation of the vessel's axial and radial position relative to the outer jacket, while the sliding support is used to allow the inner vessel displacements caused by temperature changes. The only difference between fixed supports and sliding supports is that sliding supports have fasteners only on one side. This way, the inner vessel can have thermal displacements freely without causing any thermal stress. Both of the supports carry the loads exerted by the total weight and/or inertial loads due to acceleration. Therefore, high strength between the inner vessel and outer vessel is maintained without being affected by changes in applications.
In order to reach the above-mentioned objects in the most general sense, thermally insulated support system that is positioned between vessels placed in one another in cryogenic vessel systems and that enables fixing the inner pressure vessel to the outer vessel is developed. The developed support system comprises; at least one body that is positioned between the inner vessel and outer vessel and that enables thermal insulation between them; at least two support ends that are positioned on two sides of the body, wherein one of the support ends is connected to the inner vessel support housing formed on the outer side of the inner vessel and the other support end is connected to the outer vessel support housing formed on the inner side of the outer vessel. All structural and characteristic features and all advantages of the invention will be more clearly understood from the figures given below and the detailed description addressed to the figures. Therefore, evaluation should be made by taking into account these figures and the detailed description. Figures Helping to Understand the Invention

Support system (1 1 ) of the invention is developed to be positioned between two vessels that are placed in one another in two-layer vessel (10) systems and to enable fixing the inner pressure vessel (13) to outer vessel (12) in a thermally insulated manner. For this purpose, in the most general sense, the developed support system (1 1 ) comprises; at least one body (20) that is positioned between the inner vessel (13) and outer vessel (12) and that enables thermal insulation between them; at least two support ends (30) that are positioned on two sides of the body (20), wherein one of the support ends is connected to the inner vessel support housing (15) formed on the outer side of the inner vessel (13) and the other support end is connected to the outer vessel support housing (19) formed on the inner side of the outer vessel (12).
Figure 1 shows the cross-sectional view of the support system (1 1 ) according to the invention positioned on the two-layer vessel (10). The support system (1 1 ) can be used in any two-layer vessel (10) system that requires thermal insulation and it becomes more important for systems such as cryogenic vessels, in which thermal insulation directly affects the performance of the vessel. Preferably, the support system (1 1 ) is positioned so as to have one support system (1 1 ) on each of the both ends of the vessel axis (x axis) of the two-layer vessel (10) in horizontal position. Support system (1 1 ) has two different types called fixed support system (1 1 a) and sliding support system (1 1 b) in order to be compatible with different types of two-layer vessels (10). Fixed support system (1 1 a) is used for fixation of the two-layer vessel's (10) axial and radial position relative to the outer vessel (12), while the sliding support system (1 1 b) is used to allow the inner vessel (13) displacements caused by temperature changes. The only difference between fixed support system (1 1 a) and sliding support system (1 1 b) is that, only one of the support ends (30) of the sliding support system (1 1 b) comprises a connection housing (22), fastener (31 ) and connection hole (32). Due to this property, the support end (30) of the sliding support system (1 1 b) that is positioned on the side that does not contain fasteners (31 ) can slide along the body head (21 ). This movement capability enables the inner vessel (13) to have thermal displacements freely without causing any thermal stress.
Figures 2 and 3 show the exploded view of the support system (1 1 ) according to the invention in fixed support system (1 1 a) and sliding support system (1 1 b) types, respectively. Body (20) of the support system (1 1 ) is made of fiberglass composite material. It is preferably G10 with low thermal conductivity and/or an equivalent composite (FR-4 etc.). Technical properties of G10 and FR-4 are specified below.
Support ends (30) made of 304, 316 and such quality of stainless steel or carbon steel cannot be fixed on the inner vessel (13) or the outer vessel (12) by welding. Therefore, they are fixed
between the inner vessel (13) and the outer vessel (12) by means of composite body (20) support ends (30) and fasteners (31 ). Support system (1 1 ) contains body heads (21 ) formed on the body (20) and connected to the support ends (30) on both sides. Body heads (21 ) comprises connection housings (22) that bear the fasteners (31 ). Fasteners (31 ) pass through the connection hole (32) and are fastened in the connection housing (22). Preferably, socket head bolts are used as fasteners (31 ). This way, they can be tightly fastened to gears that might be provided in the connection housing (22). Fastening can also be performed by adhesive bonding without using fasteners (31 ). A head space (34) that houses and constrains the body head (21 ) is positioned on the support end (30). An inner head (33) that increases the strength of the support system (1 1 ) by means of entering the body head (22) is placed under the head space (34). Thus, the body head (21 ) is fixed between the support end (30) and inner head (33).
Figures 4 and 5 show the cross-sectional view of the support system (1 1 ) according to the invention in fixed support system (1 1 a) and sliding support system (1 1 b) types, respectively. Support system (1 1 ) contains a radial reinforcement (18) that reinforces and increases the strength of the support end (30) around the outer vessel support housing (19). Radial reinforcement (18) fixes the support housing (19) and therefore the support (30) end it is connected to, to the outer vessel (12) at a safe resistance. Similarly, the support end (30) on the inner vessel (13) side of the body (20) is fixed with a safe resistance by means of gussets (17) that are formed around the inner vessel support housing (15) and that increase its strength. Moreover, the inner vessel support housing (15) distributes the load of supports located inside the inner vessel (13) along the body (20). A suspension component (16) is welded between the inner vessel support housing (15) and the support end (30) in order to support the support end (30). Suspension component (16) enables producing the body (20) in smaller dimensions, thus extending the heat transmission path; stops and suspends the body (20) and also enables reducing the total weight of the support system (1 1 ). Furthermore, the suspension component (16) is constrained between the support housing (15) and support end (30) in a circular manner and it distributes the load on connections in case of undesired load changes such as shaking and quaking.
Figure-6 shows thermal FEA (Finite Elements Analysis) simulation results that represent gradual heat changes along the body between the inner vessel (13) and outer vessel (14). As seen from the Figure, heat transfer is very low. Therefore, evaporation and evaporation rate are also significantly low (for a LNG vessel operating at 8 bar pressure, daily evaporation is predicted as 0.1 %). Thermal power is as low as 35 W. In contrast, thermal power in the state of the art is around 100 W or higher. Therefore, the developed technique enables reducing economical losses and the pressure increase significantly.
