ABSTRACT:
A liquefied natural gas (LNG) receiving terminal is provided, including an extraction column adapted and configured to separate a C1component from other components in a LNG stream into a C1rich stream, one of a gas condenser and a heat exchanger adapted and configured to condense the C1rich stream into a liquid, and a pump adapted and configured to increase a pressure of the liquid C1rich stream.
