System and method for liquefied natural gas production

1. A method for producing liquefied natural gas from a natural gas source, comprising:

feeding natural gas provided by the natural gas source to a precompression module;

controlling the precompression module to increase or decrease an amount of the liquefied natural gas to be produced by the method based at least in part on a level of pressure imparted by the precompression module to the natural gas fed into the precompression module;

directing the natural gas from the precompression module to a product stream of the liquefaction module,

wherein the directing of the natural gas to the product stream of the liquefaction module comprises:

cooling the natural gas in a pre-cooling heat exchanger of a cooling assembly;

further cooling the cooled natural gas from the cooling assembly in a first heat exchanger of a pair of heat exchangers downstream from the cooling assembly;

expanding the further cooled natural gas from the first heat exchanger of the pair of heat exchangers downstream from the cooling assembly in an expansion valve to produce a two-phase fluid including liquefied natural gas and a vapor phase; and

separating the liquefied natural gas from the vapor phase in a liquid separator of the liquefaction module; and

directing a process fluid to a liquefaction stream of the liquefaction module to cool at least a portion of the natural gas directed to the product stream,

wherein the directing of the process fluid to the liquefaction stream of the liquefaction module comprises:

compressing the process fluid in a compression assembly;

cooling the compressed process fluid in another heat exchanger of the cooling assembly;

further cooling the cooled, compressed process fluid in a second heat exchanger of the pair of heat exchangers;

at least partially separating natural gas liquids from the further cooled, compressed process fluid from the second heat exchanger of the pair of heat exchangers in a liquid separator to form at least a further cooled, compressed process vapor;

expanding the further cooled, compressed process vapor in a turbine of a turbomachinery to generate a refrigeration stream; and

cooling the at least a portion of the natural gas directed to the product stream with the refrigeration stream.

2. The method of claim 1 , further comprising storing the liquefied natural gas in a storage tank fluidly coupled with the liquefaction module.

3. The method of claim 2 , further comprising:

feeding the vapor phase from the liquid separator of the liquefaction module to a flash recovery module fluidly coupled with the liquefaction module; and

cooling at least a portion of natural gas from the precompression module in the flash recovery module with the vapor phase.

4. The method of claim 2 , wherein the directing of the process fluid to the liquefaction stream of the liquefaction module further comprises:

compressing the refrigeration stream in a compressor of the turbomachinery to produce a recycle stream; and

compressing the recycle stream in the compression assembly.

5. The method of claim 2 , further comprising:

generating electrical energy in a power generation module;

delivering the electrical energy from the power generation module to the liquefaction module; and

driving the compression assembly of the liquefaction module with the electrical energy.

6. The method of claim 1 , further comprising removing at least a portion of a non-hydrocarbon from the natural gas provided from the natural gas source in a conditioning module before feeding the natural gas provided from the natural gas source to the liquefaction module.
