SYSTEM AND METHODS OF OBTAINING LIQUEFIED NITROGEN USING LIQUEFIED NATURAL GAS

摘要

It describes systems and methods for producing liquefied nitrogen (LIN) using liquefied natural gas (LNG) as a refrigerant. LIN can be obtained by indirect heat exchange of at least one stream of nitrogen gas with at least two LNG streams inside at least one heat exchanger, where LNG streams are at different pressures.
