Abstract
A method for determining an operating condition of a liquefied natural gas plant () includes preparing a training model () generated by machine learning using training data in which operating conditions data including a composition of a feed gas, a composition of a mixed refrigerant, and an ambient temperature and operation result data including a production efficiency of a liquefied product containing liquefied natural gas and a heavy component of the feed gas are associated together; and determining, as one new operating condition, a composition of the mixed refrigerant that optimizes a production efficiency of the liquefied natural gas predicted by the training model () from a latest composition of the feed gas in the liquefied natural gas plant () and a latest ambient temperature.
