Abstract:
A system and method for liquefying a natural gas stream, including a liquefaction heat exchanger having at least three cooling bundles and arranged such that the natural gas stream passes sequentially therethrough. A first cooling bundle condenses heavy hydrocarbon components 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 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.

Claim (Index 6):
The system of  claim 1 , further comprising a control valve disposed between the outlet of the hydraulic turbine and the inlet of the third cooling bundle, wherein the control valve is selectively controlled based at least in part on one or more of a sensed temperature of the LNG stream prior to entering the hydraulic turbine, a sensed pressure of the LNG stream prior to entering the hydraulic turbine, a sensed temperature of the LNG stream as the LNG stream exits the hydraulic turbine, and a sensed pressure of the LNG stream as the LNG stream exits the hydraulic turbine.
