  • Process of liquefying a gaseous, methane-rich feed to obtain liquefied natural gas
    Patent number: 6272882
    Abstract: The present invention relates to a process of liquefying a gaseous, methane-rich feed to obtain a liquefied product by supplying the gaseous, methane-rich feed at elevated pressure to a first tube side of a main heat exchanger at its warm end, cooling, liquefying and sub-cooling the gaseous, methane-rich feed against evaporating refrigerant to get a liquefied stream, removing the liquefied stream from the main heat exchanger at its cold end and passing the liquefied stream to storage as liquefied product, removing evaporated refrigerant from the shell side of the main heat exchanger at its warm end, compressing in at least one refrigerant compressor the evaporated refrigerant to get high-pressure refrigerant, partly condensing the high-pressure refrigerant and separating the partly-condensed refrigerant into a liquid heavy refrigerant fraction and a gaseous light refrigerant fraction, sub-cooling the heavy refrigerant fraction in a second tube side of the main heat exchanger to get a sub-cooled heavy refriger
