Abstract
There is provided a system and method for producing liquefied natural gas (LNG). An exemplary method includes flowing a high-pressure stream of LNG through a first series of liquid turbines. The exemplary method also includes generating electricity by reducing the pressure of the high-pressure stream of LNG to form a low-pressure stream of LNG. The exemplary method additionally includes bypassing any one the liquid turbines that has a failure while continuing to produce electricity from the first series.
Claims6
A method for generating electricity from liquid turbines, comprising:
- in a normal mode, flowing a high-pressure liquid stream through a first plurality of n liquid turbines coupled in a first series, wherein, after a first turbine in the series, an inlet of each of a second through an n−1 liquid turbine is coupled to an outlet of a liquid turbine;
- generating electricity from the first series by removing energy from the high-pressure liquid stream to form a low-pressure liquid stream;
- bypassing any one of the first plurality of liquid turbines that has a failure while continuing to produce electricity with the remaining turbines of the first series;
- and
- operating the first plurality of liquid turbines in the first series that are not bypassed to maintain a pressure, temperature, and flow rate of the low-pressure liquid stream to be the same as a pressure, temperature, and flow rate of the low-pressure liquid stream when operating in the normal mode.
