A mixed refrigerant stream () comprising a first mixed refrigerant is passed through one or more heat exchangers () to provide a cooled mixed refrigerant stream (). At least a fraction of a cooling stream () comprising a second mixed refrigerant is expanded () to provide one or more expanded cooling streams (), at least one of which may be passed through one or more of the heat exchangers (), to cool the mixed refrigerant stream () thereby providing the cooled mixed refrigerant stream () which is used to cool () a hydrocarbon stream (). The temperature (T) and the flow (F) of at least part of the cooled mixed refrigerant stream () is monitored, and the flow (F) of the cooling stream () is controlled using the flow Fand the temperature T
