Description

Technical Field

[0001] This invention relates to a technique for arranging factory buildings in a factory, and more particularly to a factory building arrangement mechanism and a factory building arrangement method. Background Technology

[0002] Factories that use various machines to process materials include the following: natural gas plants that liquefy or separate and recover natural gas liquids; petroleum refining plants that distill or desulfurize crude oil or various intermediate fractions; chemical plants that produce petrochemicals, intermediate chemicals, polymers, etc.; pharmaceutical plants that manufacture pharmaceuticals; waste treatment plants that process low-level radioactive waste; and plant factories that produce vegetables and other plants. These factories are constructed by combining numerous machines.

[0003] Generally speaking, among the many machines that make up a factory, in addition to the machines that perform the processing of the objects being processed, there are also electrical-related machines or control-related machines.

[0004] Regarding these electrical or control-related machines, from the perspective of shortening the factory construction period or post-construction maintenance and management, the following situation exists: each of these electrical or control-related machines is centrally located in a factory building independent of the main factory machinery area (e.g., Patent Document 1). These factory buildings are situated on a foundation or a structure on the foundation via pillars supporting the factory buildings, the foundation being located on the foundation of the land where the factory is built.

[0005] When installing factory buildings, the strength design of the foundation or structure should be adapted to withstand the swaying of the buildings, which may be caused by factors such as strong winds, wind pressure, or earthquakes. Furthermore, sometimes a construction method is used where modules with factory buildings mounted on their structures are built in a remote factory and then transported and configured to the factory site. In this case, the swaying of the factory buildings during transportation must also be considered in the structural strength design.

[0006] When conducting these strength designs, if a structure is used to rigidly connect the foundation or framework of the factory building, the strength design must be based on the premise that moments will be applied to the framework or foundation due to swaying. As a result, the foundation needs to be larger or larger steel needs to be used to construct the framework, which becomes a significant reason for the increased construction cost of the factory.

[0007] On the other hand, while using screws for pin engagement can minimize the torque applied to the structure or foundation, it requires a large number of screws due to low fatigue strength against swaying during sea transport, necessitating a massive baseplate. Furthermore, the plant needs to be constructed with the screw holes at the interconnecting points of the foundation or structure aligned with the holes in the baseplate, increasing the difficulty of installation. This method may also increase the plant's construction costs.

[0030] [The effects of the invention]

[0031] According to this technology, instead of directly connecting the pillars supporting the factory building to the mounting surface of the factory building, side stops and top surface stops are used for mounting.

This structure can suppress the magnitude of the torque applied to the mounting surface due to factory building swaying, thus reducing the need for large-scale foundations or structures and minimizing construction costs.

[0053] The following describes the following implementation method: As an example of a plant, the LNG plant 1, which produces liquefied natural gas (LNG), uses the placement mechanism (placement method) disclosed herein to place the plant building.

[0054] Figure 1 This is a schematic side view of a portion of LNG plant 1. LNG plant 1 includes a plurality of machines for performing various processes such as separating liquids contained in gaseous natural gas (NG), removing impurities such as mercury or water, and heavy components, and then cooling and liquefying NG to produce LNG.

[0055] Furthermore, LNG plant 1 is also equipped with auxiliary equipment such as oil heaters or boilers for heating the heat medium (e.g., hot oil or steam) used in various heating operations implemented in each process, and gas turbine generators or gas engine generators for supplying electricity consumed within LNG plant 1. These auxiliary equipment also include numerous machines.

[0056] The numerous machines constituting LNG plant 1 are grouped, for example, according to the type of processing or auxiliary equipment, and are located in multiple structures 100. In this example, the structure 100 is configured to allow these machines to be arranged vertically as a multi-layered, steel-framed structure.

[0057] For example, in Figure 1A processing unit 11 is centrally located, which performs one of the processes for producing LNG. The processing unit 11 includes static machines 101 (excluding power units), such as towers or heat exchangers, dynamic machines 102 (including power units), such as pumps, and connecting pipes (not shown), which connect the static machines 101 and dynamic machines 102 to each other or to the dynamic machines 102 on the pipe rack 12 side (described later).

[0058] and, Figure 1 In the middle, a pipe rack 12 is arranged on the right side of the processing unit 11. The pipe rack 12 is a structure in which a plurality of pipes 103 are arranged on the structure 100 to facilitate the flow of fluid exchange between the processing units 11.

[0059] Moreover, in Figure 1 The upper surface of the tube rack 12 shown is neatly arranged with a plurality of air-cooled heat exchangers (ACHEs) 104, which are used to cool the fluids processed in the specified processing section 11.

[0060] In the machines installed in LNG plant 1, power that has been transformed according to the rated voltage of each power-consuming machine is supplied to power-consuming machines such as dynamic machine 102 that consume electricity due to power units, etc.

[0061] Therefore, for these power-consuming machines, there are power supply machines such as transformers for voltage conversion or power supply control equipment, interruptors, or circuit breakers for controlling the power supply to each power-consuming machine. These power supply machines are housed in a building 13, which includes an outer contour structure separated from the surrounding area. The building 13 is called a substation and is located within the structure 100 that houses the power-consuming machines.

[0062] Furthermore, the machines installed in LNG plant 1 include various controlled machines such as flow control valves that adjust the flow rate of fluids or pressure control valves that adjust the pressure in the tower tank, flow control valves that increase or decrease the flow rate of heat medium or cold medium to adjust the outlet temperature of the heat exchanger of the fluid to be adjusted, and on / off valves that perform opening and closing actions according to the liquid level in the tower tank.

[0063] Each of these controlled machines is equipped with a controller, and the following control loop is constructed: based on the results obtained by the detection unit detecting the flow rate, pressure, temperature or liquid level of the fluid, the controller outputs a control signal to the controlled machine to control the operation of each controlled machine.

[0064] At this time, a control information output device, referred to as a Field Control Station (FCS), is provided. Located in the central control room, which performs overall control of the LNG plant 1, this control information output device outputs information related to the operation control of the controlled machines, such as flow rate setpoints, pressure setpoints, and temperature setpoints received from operators or automatic control devices, to the controllers that control the operation of the controlled machines. It also outputs information such as fluid flow rate, pressure, temperature, or liquid level detected by the detection unit to the central control room. This control information output device is also housed within a building 13, which includes an outer contour structure separated from the surrounding area. This building 13, referred to as the machine control room, is independent of the aforementioned substation and is located within the structure 100 that houses the controlled machines.

[0065] Figure 1 In the example shown, the processing unit 11, the structure 100 of the pipe rack 12, and the plant 13, which serves as a substation or machine control room, are located on a concrete foundation not shown, which is pre-built on land for the construction of the LNG plant 1.

[0066] At this time, the factory building 13 is placed on the placement surface 2 of the concrete foundation by means of a plurality of pillars 131, which are arranged to extend downward from the lower surface of the outer contour structure constituting the factory building 13.

[0067] In installing the plant 13, the LNG plant 1 in this example does not use rigid joints, but instead employs a mechanism for installing the support columns 131 on the installation surface 2. Hereinafter, reference will be made to... Figures 2-5 On the one hand, the detailed structure of the resettlement facility is explained.

[0068] Figure 2 This is a partial fracture perspective view showing the condition of the lower end of the support column 131 of the resettlement building 13 on resettlement surface 2, using the resettlement mechanism described in this example. Furthermore, Figures 3-5 An exploded perspective view showing the sequence of installing support pillars 131 on the installation surface 2 using the installation mechanism.

[0069] like Figure 3 As shown, a base plate 132 is provided at the lower end of the support column 131, and this base plate 132 comprises a rectangular steel piece with a flat lower surface. The base plate 132 is joined to the support column 131, for example, by welding. The base plate 132 forms part of the mounting mechanism in this example.

[0070] On the other hand, a flat mounting area 20 is provided on the upper surface of the mounting surface 2, for example. After the base plate 132 is mounted on the mounting area 20, the plant 13 is mounted using a mounting mechanism. At this time, the base plate 132 is not fixed to the mounting surface 2 by welding or screws.

[0071] like Figure 2 As shown, the mounting mechanism also includes: a side stop 41 and a side stop 41a, which are located opposite to the side of the base plate 132 placed on the mounting area 20 of the mounting surface 2, separated by a gap; and a yoke 32, which is an upper surface stop, located at a height opposite to the upper surface of the base plate 132, separated by a gap.

[0072] like Figure 3 As shown, the side stops 41 and 41a are components arranged corresponding to the four sides of the base plate 132, respectively, in a manner that surrounds the mounting area 20 where the base plate 132 is arranged. Each side stop 41 and 41a is, for example, made of steel. Figure 2 In the example of the mounting mechanism shown, the two side stops 41 arranged along the rigid arm 32 include plate-like members. On the other hand, the stop 41a arranged between the support 31 (described later) and the base plate 132 includes a short rod-like member (see reference) in a direction intersecting the side of the base plate 132. Figure 2 (The area indicated by cutting away a portion of the support portion 31).

[0073] In addition, it can also be used as a substitute Figure 2 As shown in the example, a common thick plate-shaped side stop 41 is provided on all four sides of the base plate 132. In this case, the following structure can be illustrated: a notch is provided at the lower end of the support 31a to avoid interference with the side stop 41.

[0074] Regarding the arrangement of the side stops 41 and the side stops 41a, the positions are set as follows: when the base plate 132 is placed in the mounting area 20, they face each other with a gap of about a few millimeters (mm) to a few micrometers (cm) between them.

[0075] By placing the base plate 132 in the placement area 20 in the stated state, the side stop portions 41 and 41a can be separated by a gap and face each other relative to the side of the base plate 132 (the process of making the side stop portions 41 and 41a face each other).

[0076] Each side stop 41 and side stop 41a is fixed to the mounting surface 2 surrounding the mounting area 20. There is no particular limitation on the method of fixing the side stops 41 and side stop 41a; a fixing method suitable for the components constituting the mounting surface 2 can be used. For example, if the mounting surface 2 is made of concrete, the mounting surface 2 with screw holes can be fastened to the side stops 41 and side stop 41a using screws. Furthermore, if the mounting surface 2 is made of steel, the side stops 41 and side stop 41a can be joined to the mounting surface 2 using a pin connection.

[0077] like Figure 4 As shown, a thin, elongated spacer plate 42 is inserted into the gap between the opposing base plate 132 and each side stop 41 and side stop 41a in a manner that fills the gap (the process of inserting the spacer plate 42). The spacer plate 42 serves to prevent the support column 131 (factory building 13) from shifting in the direction along the mounting surface 2. The spacer plate 42 is made of metal or hard rubber and is fastened to the side wall of the base plate 132 using screws 421.

[0078] Moreover, such as Figure 2 , Figure 3 As shown, support portions 31 for supporting rigid arms 32 are provided at positions facing the side stops 41a of the rod-shaped plates. For example, the support portion 31 includes a plate-shaped member having a side wall extending parallel to the edge of the rectangular base plate 132. These support portions 31 form a group, supporting the left and right ends of the two rigid arms 32 arranged to clamp the support column 131. Each support portion 31 is, for example, made of iron or steel.

[0079] In the mounting mechanism of this example, two rigid arms 32 are provided, facing each other with a gap between two regions on the upper surface of the base plate 132, which is set relative to the clamping support column 131. Corresponding to the arrangement of these rigid arms 32, a set of support portions 31 are arranged to clamp the two regions respectively, so as to support the rigid arms 32 in a state that extends along the upper surface of the base plate 132 (the process of setting the rigid arms 32).

[0080] These support portions 31 are fixed to the mounting surface 2 in the same way as the side stops 41 and the side stops 41a. For example, if the mounting surface 2 is made of concrete, a base plate for fixing can be provided at the lower end of the support portion 31, and the base plate can be fastened to the mounting surface 2 using screws. Moreover, if the mounting surface 2 is made of iron or steel, the support portion 31 can be connected to the mounting surface 2 by a pin engagement.

[0081] In the figure, symbol 311 refers to the reinforcement portion that strengthens the support portion 31 in fixing the mounting surface 2. The shape or number of reinforcement portions 311 is not particularly limited. For example, it can also be as follows... Figure 2 , Figure 3 As shown, on the side opposite to the support surface of the support arm 32, along the height direction of the support portion 31, two plate-shaped reinforcing portions 311 are provided with a π-shaped cross-section of the support portion 31 and the reinforcing portion 311, spaced apart from each other. Furthermore, three or more reinforcing portions 311 may also be provided.

[0082] Alternatively, a structure may be used in which multiple reinforcing parts 311 are provided between two plates arranged in parallel with an open gap, and the plate on one side of the structure is used as a support part 31 to support the rigid arm 32.

[0083] like Figure 5 As shown, the rigid arm 32 is a thick plate-shaped component erected between the support surfaces of the sets of support portions 31 arranged facing each other and clamping the base plate 132. The rigid arm 32 is made of steel, for example. Each rigid arm 32 is positioned at an opposing height relative to the upper surface of the base plate 132, with a gap of a few millimeters to a few centimeters. Each rigid arm 32 is joined to the support surface of the support portion 31, for example, by welding.

[0084] Furthermore, unlike the gap between the bottom plate 132 for inserting the aforementioned partition plate 42 and the side of the side stop 41 and the side of the side stop 41a, the gap between the upper surface of the bottom plate 132 and the rigid arm 32 is not a state in which other components are inserted.

[0085] The above is based on usage. Figures 3-5 The described sequence refers to the state in which the support column 131, placed in the placement area 20, is placed on the placement surface 2 by the placement mechanism. Figure 2 In addition, the multiple pillars 131 of the plant 13 are respectively placed in the pre-defined placement area 20 of the placement surface 2 using the aforementioned placement mechanism. Through these placement operations, the plant 13 is positioned within the designated land area of ​​the LNG plant 1.

[0086] The factory building 13 installed using the installation mechanism described in this example may sway due to strong winds or earthquakes. In this case, in the installation mechanism of this example, side stops 41 and side stops 41a are arranged at the lower ends of the multiple support columns 131 that support the factory building 13 from the lower surface, facing each side of the base plate 132 placed in the mounting area 20. Furthermore, spacers 42 are inserted into the gaps between these base plates 132 and each side stop 41 and side stops 41a. According to this structure, even if the force of the lateral component of the swaying exceeds the influence of the factory building 13's own weight, the factory building 13 (each support column 131) can be prevented from shifting in the direction along the mounting surface 2.

[0087] Furthermore, if the force of the longitudinal component of the swaying exceeds the weight of the plant 13, the base plate 132 will lift off the mounting surface 2. In this case, the mounting mechanism of this example provides rigid arms 32 that face each other with gaps between two areas on the upper surface of the base plate 132, which are positioned relative to the clamping support 131. According to this structure, the base plate 132 can be pressed down to prevent it from lifting above a predetermined height defined by the gap with the rigid arms 32. By suppressing the height of this gap to approximately a few millimeters to a few centimeters, the magnitude of the impact following the lifting and subsequent fall of the base plate 132 can be suppressed within a predetermined range, thus preventing damage to the base plate 132 itself or the machinery housed within it.

[0088] On the other hand, the base plate 132 is not excessively placed on the mounting surface 2 (mounting area 20) and is not directly joined to the mounting surface 2. Therefore, compared to the case where the support column 131 is connected to the mounting surface 2 by rigid connection, almost no torque is applied to the mounting surface 2 when the plant 13 sways. As a result, the large size of the foundation can be suppressed, and the increase in the construction cost of the LNG plant 1 can be suppressed.

[0089] Figure 6 for Figure 2 The example shown is a variation of the mounting mechanism. In this example, the support portion 31a supporting one end of the rigid arm 32 and the support portion 31a supporting the other end are separated between the two rigid arms 32.

[0090] At this time, with Figure 2 Compared to the described side stop 41a, it does not interfere with the support 31a, so the same thick plate-shaped side stop 41 as the one provided along the rigid arm 32 can also be used.

[0091] Next, on the one hand, refer to Figure 7 , Figure 8 On the one hand, an implementation method is described in which a plant 13 is set up in module 1a of LNG plant 1, which is a transportable structure.

[0092] In recent years, when constructing an LNG plant 1, the following method has sometimes been adopted: dividing the LNG plant 1 into multiple modules 1a, and constructing modules 1a in a plant far from the construction site, each with a static machine 101 or a dynamic machine 102 configured on the architecture 100. After the constructed modules 1a are transported and configured to the construction site, they are interconnected to form the LNG plant 1.

[0093] In the example described, sometimes a factory building 13 is pre-installed on module 1a. In this case, the structure 100 of module 1a forms the installation surface 2 of the factory building 13. At this time, the installation mechanism of the factory building 13 is located on the iron frame structure that constitutes the structure 100.

[0094] Here, when transporting module 1a, which weighs several hundred to several thousand tons, water transport is employed using transport vessel 5. However, during the water transport of module 1a, transport vessel 5 is subject to up-and-down rocking due to waves, thus continuously applying an up-and-down rocking force to module 1a. In this situation, if... Figure 2 If the installation mechanism described above is designed such that there is a gap between the upper surface of the base plate 132 and the rigid arm 32, then the base plate 132 may lift up whenever a large sway occurs, and repeatedly collide with the rigid arm 32, causing damage to the rigid arm 32.

[0095] Therefore, during the transport of module 1a, such as Figure 8 As shown, a buffer plate 43 is inserted into the gap between the upper surface of the base plate 132 and the rigid arm 32 (the process of inserting the buffer plate 43). The buffer plate 43 is made of, for example, wood or hard rubber. By placing the buffer plate 43 between the rigid arm 32 and the base plate 132, the force repeatedly applied to the rigid arm 32 by the swaying of the module 1a is reduced, and damage to the rigid arm 32 can be suppressed.

[0096] After the water transport is completed and the module 1a is installed on the construction site of LNG plant 1 via subsequent land transport, the buffer plate 43 is removed, opening the gap between the base plate 132 and the rigid arm 32 (the process of removing the buffer plate 43). After the installation of module 1a is completed, the possibility of large swaying of the plant 13 is relatively small compared to the water transport period. Therefore, by opening the gap filled by the buffer plate 43, as long as large swaying such as the base plate 132 lifting does not occur, the plant can be set to a state where no force is applied from the base plate 132 to the rigid arm 32.

[0097] Here, Figure 8 The symbol 431 indicates a stop used to prevent the buffer plate 43 from falling off the gap between the base plate 132 and the rigid arm 32. For example, the stop 431 is made of wood or hard rubber and is fastened to the buffer plate 43 by screws. By using the stop 431, the buffer plate 43 can be prevented from falling off even if the base plate 132 is not fastened with screws. Therefore, it is not necessary to provide screw holes in the body of the base plate 132.

[0098] If screw holes are provided in the base plate 132, water may accumulate in the screw holes and cause corrosion after the buffer plate 43 is removed. Therefore, by using the stopper 431, the buffer plate 43 is prevented from falling off without the use of screws, thereby preventing corrosion of the base plate 132 caused by the formation of screw holes.

[0099] The above describes an embodiment in which the placement mechanism of this disclosure is applied to the plant 13 that is also located in the LNG plant 1. However, the plant to which the placement mechanism is applicable is not limited to the LNG plant 1. For example, the placement mechanism of this disclosure can also be applied to the plant 13 that is also located in the following plants: a natural gas plant that separates and recovers natural gas liquid contained in natural gas; a petroleum refining plant that distills or desulfurizes crude oil or various middle fractions; a chemical plant that produces petrochemicals or intermediate chemicals, polymers, etc.; a pharmaceutical plant that manufactures pharmaceuticals or their intermediate products; a waste treatment plant that treats low-level radioactive waste; a plant factory that produces vegetables and other plants; and other plants that treat various objects (excluding machine manufacturing plants that manufacture automobiles, machinery, electronic equipment, semiconductor devices, etc.).

[0100] At this time, the machines installed in the factory that process the objects to be processed, or the machines installed in the auxiliary equipment, are not limited to, for example, Figure 1 The LNG plant 1 illustrated is configured in the framework 100, which serves as the skeleton structure. For example, these machines can also be housed in the main plant building, which serves as the outer contour structure, and the installation mechanism in this example can be used to install the smaller plant 13, which is also located in the main plant building.

[0101] Furthermore, the types of machines housed in the plant 13 housed by the installation mechanism in this example are not limited to the power supply machines or control information output machines described above. For example, the installation mechanism in this example can also be used to install a part of a plant 13 that houses machines related to the processing of objects being processed or auxiliary equipment related to the supply of heat media, electricity, etc.
