Abstract

Provided is a method of operating a natural gas liquefaction apparatus stably and efficiently in accordance with the change in weather condition. In a method of operating a natural gas liquefaction apparatus (1) including compressors (35 and 36) for refrigerant to be used for liquefying natural gas and a plurality of air-cooled heat exchangers (2) configured to cool the compressed refrigerant, an analysis step (P1) includes determining, by numerical analysis, predicted values of a temperature of cooling air under conditions with changes in temperature of a site in which the natural gas liquefaction apparatus (1) is installed, wind direction, and wind speed, in consideration of a case in which exhaust air discharged from the air-cooled heat changers (2) is taken in again. A weather data acquisition step (P2) includes acquiring weather data on the temperature of the site, the wind direction, and the wind speed, and a determination step (P3 to P5) includes determining the necessity of operation adjustment of the natural gas liquefaction apparatus (1) by predicting a change in load of the compressors (35 and 36) based on a predicted value of the temperature of the cooling air, which corresponds to the weather data, and an operating condition of the plant determined through the use of the predicted value.
