Gas processing facility

1. A gas processing facility for performing at least one of liquefaction of natural gas, separation and recovery of a component in the natural gas, production of synthesis gas from the natural gas, or synthesis of a compound containing the natural gas or the synthesis gas as a raw material,

the gas processing facility comprising:

an air-cooled heat exchanger configured to supply cooling air taken through an intake into a tube through which a fluid to be cooled is caused to flow, to thereby cool the fluid to be cooled;

a windshield arranged at the intake of the air-cooled heat exchanger configured to block wind flowing into a space below the air-cooled heat exchanger, wherein the windshield is arranged at a position facing an inflow direction of the wind; and

a mist supply section configured to supply mist, which is obtained by spraying demineralized water to the cooling air to be taken into the air-cooled heat exchanger, to thereby cool the cooling air,

the mist supply section being configured to spray the demineralized water from a lateral position on an upstream side of the intake.

2. The gas processing facility according to claim 1 , further comprising a pipe rack having a framework structure, which is configured to hold a bundle of pipes through which the fluid to be cooled is caused to flow,

wherein the air-cooled heat exchanger is arranged in a top portion of the pipe rack at a position above the bundle of the pipes in a state in which the intake is oriented downward, and

wherein the mist supply section is configured to spray the demineralized water from a lateral side toward the space below the air-cooled heat exchanger having the intake opened therein.

3. The gas processing facility according to claim 2 ,

wherein the pipe rack comprises a floor configured to partition the bundle of the pipes and the air-cooled heat exchanger, and

wherein the demineralized water is sprayed from the mist supply section toward a space between the air-cooled heat exchanger and the floor.

4. The gas processing facility according to claim 3 , wherein the mist supply section is configured to spray the demineralized water at a height position within a range of up to two thirds of a lower side of the height from the floor to the intake of the air-cooled heat exchanger.

5. The gas processing facility according to claim 2 ,

wherein the pipe rack is formed into a rectangle when viewed from an upper surface side of the pipe rack,

wherein the air-cooled heat exchanger comprises a plurality of air-cooled heat exchangers arranged side by side in series along a short side of the rectangle, and

wherein a plurality of groups, each including the plurality of air-cooled heat exchangers, are arranged side by side along a long side of the rectangle.

6. The gas processing facility according to claim 5 , wherein the mist supply section is arranged along the long side of the pipe rack.

7. The gas processing facility according to claim 2 , wherein the mist supply section comprises a plurality of spray nozzles configured to spray the demineralized water at different height positions.

8. The gas processing facility according to claim 7 , wherein, out of the plurality of spray nozzles configured to spray the demineralized water at the different height positions, a part of the plurality of spray nozzles is configured to spray the demineralized water in a direction opposite to a direction opposed to the space below the air-cooled heat exchanger.
