Abstract: An air-cooled heat exchanger (6) arranged in a gas processing facility for performing a liquefaction process of natural gas is configured to supply cooling air to a tube (63) through which a fluid to be cooled is caused to flow, to thereby cool the fluid to be cooled, and a mist supply section (7) is configured to supply mist obtained by spraying demineralized water, to thereby cool the cooling air. Further, the mist supply section (7) is configured to spray the demineralized water from a lateral position on an upstream side of an intake.

Abstract: Provided is a gas processing facility capable of enhancing the performance of an air-cooled heat exchanger while suppressing the influence on apparatus from spraying of demineralized water to the air-cooled heat exchanger to be used in a processing of natural gas. An air-cooled heat exchanger arranged in the gas processing facility for performing a liquefaction process of natural gas and the like is configured to supply cooling air to a tube through which a fluid to be cooled is caused to flow, to thereby cool the fluid to be cooled, and a mist supply section is configured to supply mist obtained by spraying demineralized water, to thereby cool the cooling air. Further, the mist supply section is configured to spray the demineralized water from a lateral position on an upstream side of an intake.

Abstract: A liquefied gas producing facility is provided and includes: a first heat exchanger, a first refrigerant compressor, a second heat exchanger, a second refrigerant compressor, air-cooling heat exchangers for a first refrigerant, air-cooling condensers for a first refrigerant, air-cooling heat exchangers for a second refrigerant, air-cooling condensers for a second refrigerant and a mist spraying device. The liquefied gas producing facility can produce liquefied gas by liquefying feed gas which contains methane as a main component.
