Abstract
A method for improving the efficiency of liquefied natural gas (LNG) liquefaction including receiving a gas feed stream at an LNG facility, condensing the gas feed stream into an LNG product stream, removing nitrogen from the LNG product stream via a nitrogen rejection unit coupled with the LNG facility to produce a final LNG product stream, analyzing one or more process samples taken throughout the liquefaction and nitrogen removal processes via mass spectrometry, and adjusting one or more aspects of the LNG processing system based on the analysis.

A method for liquefied natural gas (LNG) liquefaction, the method comprising:
- receiving a gas feed stream;
- condensing the gas feed stream into an LNG product stream;
- removing nitrogen from the LNG product stream to produce a final LNG product stream;
- and
- monitoring component content by performing a compositional analysis of one or more process samples via mass spectrometry.
A method for liquefied natural gas (LNG) liquefaction, the method comprising:

- condensing the gas feed stream into an LNG product stream;
- removing nitrogen from the LNG product stream to produce a final LNG product stream;
- monitoring a component content by performing a compositional analysis of one or more process samples via mass spectrometry;
- and
- adjusting one or more LNG facility parameters of an LNG facility based on the component content.
A system for liquefied natural gas (LNG) liquefaction, the system comprising:
- an LNG facility operable to condense a gas feed stream received at the LNG facility into a LNG product stream;
- a nitrogen rejection unit coupled with the LNG facility, the nitrogen rejection unit operable to remove nitrogen from the LNG product stream to produce a final LNG product stream;
- and
- an analyzer coupled with the LNG facility or the nitrogen rejection unit operable to obtain mass spectrometry data for one or more process samples, the analyzer including a mass spectrometer.
