Patent ID: 7637122

Claim:
A method of liquefying a gas, the method comprising: providing a source of gas and flowing a portion of the gas from the source; dividing the portion of the gas into at least a process stream and a cooling stream; flowing the process stream sequentially through a first compressor and a first side of at least one heat exchanger; flowing the cooling stream sequentially through a second compressor and a second side of the at least one heat exchanger; expanding at least a portion of the process stream subsequent flowing the process stream through the first side of at least one heat exchanger to produce a liquid; producing a slurry of liquid natural gas and solid carbon dioxide from the at least a portion of the process stream within a liquid-gas separator; and transferring at least a portion of the slurry from the liquid-gas separator to at least one transfer tank to maintain adequate transfer pressure of the slurry delivered from the separator.
