  • this method is adopted, as shown in FIG. 3, under the condition that the SS / CR50 is arranged in the space below the pipe rack in which the pipe 42 through which the flammable fluid flows is arranged, the building constituting the SS / CR50
  • it is highly likely that extremely high explosion resistance is required.
  • the weight of the SS / CR50 also increases, and in order to hold the SS / CR50, the diameter of the steel frame material constituting the frame 30 also increases, which causes an increase in the material cost and the transportation cost of the frame 30.
  • the module M of this example is the frame device 6 in each frame 30.
  • High degree of integration In other words, in the module M, it can be said that the frame equipment 6 for handling the flammable fluid is centrally arranged in a limited area.
  • each module M is arranged with a gap between the modules M and the other adjacent modules M. That is, unlike the conventional LNG plant in which a large number of devices are arranged on the ground, the LNG plant composed of the module M has a structure that can be easily evacuated through the gap once it goes out of the module M. ing. Further, unlike the central control room where the operator of the LNG plant is resident, each SS / CR50 is usually a building without personnel except at the time of inspection or maintenance.
  • the SS / CR50 arranged in each module M has a plurality of doorways at different positions so as to open toward the side surface of the frame 30 (doors of the doorways in the figure). 52) is provided.
  • the doorway By arranging the doorway in this way, even if a person is staying in the SS / CR50, it can be immediately evacuated to the outside of the module M in the event of a fire or the like.
  • the SS / CR50 can be overweight and the SS / CR50 can be increased. It is also possible to suppress an increase in the diameter of the steel frame material of the frame 30 to be held.
  • the SS / CR50 provided in the module M of this example has an air intake for keeping the internal pressure of the SS / CR50 higher than the atmospheric pressure as one of the explosion-proof structures.
  • the pipe 531 is connected.
  • the intake pipe 531 is provided so as to extend upward along the side surface of the frame 30.
  • the air intake portion 532 at the end of the intake pipe 531 is arranged at a position higher than the combustible material handling device arranged in the frame 30 of the module M.
  • the air intake unit 532 is arranged at a position higher than the arrangement position of the ACHE 41.
  • the module M is constructed in a construction site called a module yard, which is different from the construction site of the LNG plant.
  • the SS / CR50 may be assembled in a factory called a shop, which is located in a place different from the module yard and is provided near a manufacturer of a power supply device or a control information output device.
  • the module M'under construction arranges the frame equipment 6 on each floor while assembling the frame 30 in order from the lower floor. At this time, when the SS / CR50 is arranged in the lowermost layer of the frame 30, it seems that the construction of the module M'under construction cannot be started unless the assembly of the SS / CR50 in the shop is completed.
  • the module M construction period may become excessively long. Therefore, in the module M'under construction shown in FIG. 4A, the construction of the module M'under construction is advanced leaving a space in which the SS / CR50 is arranged. During this period, the SS / CR50s placed on the gantry 501 will be assembled in parallel at the shop.
  • the SS / CR50 assembled at the shop is transported to the module yard, and the SS / CR50 is inserted into the arrangement area under the pipe rack. After that, for example, by connecting the frame 501 and the frame 30, the SS / CR50 is installed in the module M (FIG. 4B).
  • the power supply equipment in the SS / CR50 and the power consumption equipment in the frame 30 are connected via a feed line, and the control information output in the SS / CR50 is output.
  • the device and the controller and the detection unit of the controlled device in the frame 30 are connected to each other via a signal line. At this time, if the connection of these feeder lines and signal lines is completed in the module M in which the SS / CR50 is already installed, the man-hours after installing the module M on the construction site will be significantly increased. Can be reduced.
  • a power supply device housed in the SS / CR50 and a power consumption device arranged in the same frame 30 are connected via a feeder line 51. Connect and perform power supply test.
  • the feeder line 51 is shown by a broken line.
  • a power consuming device having a plurality of types of voltage levels having different working voltages may be arranged.
  • a power consuming device having a medium voltage or low voltage level of less than 1000 V is relatively easy to connect to the power supply device and to perform an energization test. Therefore, it is suitable for prior connection work and energization test work before the module M is installed on the construction site.
  • a power consuming device having a high voltage level of 1000 V or higher requires a large connection jig and test device, and may not be suitable for connection work and energization test work in a module yard.
  • the power consuming device having a voltage level of 1000 V or more has the power corresponding to the voltage level. It may be in a state of not being connected to the supply device. In the example of the module M shown in FIG. 3, a large pump 6a corresponds to this.
  • the power consuming device having a voltage level of less than 1000 V is in a state of being connected to a power supply device corresponding to the voltage level. In the example shown in FIG. 3, each ACHE 41 corresponds to this.
  • control information output device when the control information output device is housed in the SS / CR50, the control information output device is connected to the controlled device housed in the frame 30 via a signal line. Work, control signal transmission / reception test work may be performed. In FIG. 3, the description of the control information output device, the controlled device, and the signal line is omitted.
  • the module M on which the SS / CR50 is installed will be transported to the construction site using a carrier or a transport vehicle.
  • the module M is connected to the foundation pre-installed in the site, and the lower end of the frame 30 and the lower end of the base 501 of the SS / CR50 are fixed to the foundation.
  • Module M is installed at a predetermined position, pipes are connected between multiple modules M and external devices of module M, and power supply lines are connected from power generation equipment to each SS / CR50 which is a substation.
  • the signal line is connected between the main control room and each SS / CR50 which is the equipment control room. Further, in each module M, if the connection between the high-voltage power consuming device of 1000 V or more and the power supply device corresponding to the voltage level and the power supply test are not completed, these operations are also performed. By carrying out these operations, an LNG plant can be constructed.
  • the module M of this example is provided in the frame 30, and the SS / CR50 in which the power supply device or the control information output device is housed is arranged in the lower region of the pipe rack. By arranging the building using the space below the pipe rack, it is possible to contribute to the reduction of the installation area of the module M.
  • the position where the SS / CR50 is arranged is not limited to the lowest layer of the frame 30.
  • SS / CR50 may be arranged at height positions of two or more layers as long as it is inside the frame 30 excluding the upper surface (top layer) of the frame 30.
  • the plant that can be constructed by using the above-mentioned module M provided with SS / CR50 is not limited to the LNG plant.
  • This technology can also be applied to a natural gas processing plant that separates and recovers LPG and natural gas liquid, which is a heavy component, from natural gas.
