(54) Title: HYDRAULIC TURBINE BETWEEN MIDDLE AND COLD BUNDLES OF NATURAL GAS LIQUEFACTION HEAT EXCHANGER (57) : A system and method for liquefying a natural gas stream, including a liquefaction heat exchanger having at least three cooling bun- dles and arranged such that the natural gas stream passes sequentially therethrough. A first cooling bundle condenses heavy hydrocarbon com- ponents in the natural gas stream. A second cooling bundle liquefies the natural gas stream. A third cooling bundle sub-cools the LNG stream. A hydraulic turbine has an inlet operationally connected to an outlet of the 300 second cooling bundle, and an outlet operationally connected to an inlet of the third cooling bundle. The hydraulic turbine cools the LNG stream and reduces the pressure of the LNG stream to form a reduced-pressure LNG stream.
