Abstract

The present disclosure provides a nitrogen removal unit (NRU) for removing nitrogen from a LNG feed stream. The NRU employs a nitrogen stripping column and a nitrogen removal column to cooperatively remove nitrogen from the LNG. An overhead stream of nitrogen-containing LNG from the nitrogen stripping column is directed to the downstream nitrogen removal column for further nitrogen removal. The nitrogen removal column outputs a nitrogen-rich overhead stream that can be vented to the atmosphere or processed into a usable end product, and a methane-rich bottom stream that is supplied to the nitrogen stripping column as methane-rich reflux. A denitrogenated LNG bottom stream from the nitrogen stripping column may be directed to one or more storage tanks. The NRU may be a subsystem of a LNG plant.
