Embodiment

[0083] (simulation)

[0084] The difference in the diffusion state of combustible gas depending on the presence or absence of the exhaust fan 41 installed on the floor of the safe area 23 (gas discharge area 40 ) was analyzed by a CFD (Computational Fluid Dynamics) model.

[0085] A. Simulation conditions

[0086] (Example) such as Figure 7 As shown, a CFD model with an exhaust fan 41 is made on the floor of the safe area 23 to simulate the diffusion of propane gas when propane leaks from the module 21 at a speed of 12kg / s. The flow velocity of the airflow formed by the exhaust fan 41 was set to 6.7 m / s. The CFD analysis software used is FLACS (US registered trademark) v10.5Dispersionmodel of GEXCON Company.

[0087] (Comparative example) Except that the exhaust fan 41 was not provided, the same CFD model as in the embodiment was produced to simulate the diffusion state of propane gas.

Abstract

The present invention aims to provide a technique for reducing the influence of outflow of a fluid including combustibles by using a simple method. The processing plant 2, which is installed outdoor and processes a fluid including combustibles, is provided with an apparatus arrangement region 21 in which an apparatus group including a plurality of apparatuses for handling the fluid is arranged; and a gas discharge region 40 which is set to discharge a gas toward the outside of the processing plant 2 when the fluid flows out from the apparatuses and the gas of the combustibles is generated. The gas discharge region 40 is provided with an exhaust fan 41 for pushing out the gas.

Description

technical field [0001] The present invention relates to a technology capable of reducing the influence of the outflow of the fluid containing combustibles by means of a treatment facility for treating the fluid containing combustibles. Background technique [0002] When designing processing facilities that process fluids containing combustibles, such as LNG facilities and oil refining facilities, it is necessary to consider safety measures to prevent the fluid from igniting combustibles if it leaks outside. [0003] As an example of safety measures, measures such as establishing an area (safety area) where no machine is installed between areas where machines are installed to suppress the pressure rise of the blast wave, and enhancing the strength of the main body of the machine and the frame supporting the machine to make it more explosion-proof, etc. measures. [0004] At this time, it is difficult to construct a sufficiently large safety zone due to the limitation of the ...
