Abstract: A method for producing liquid natural gas (LNG) includes the following steps. Compressor stations forming part of existing natural-gas distribution network are identified. Compressor stations that are geographically suited for localized distribution of LNG are selected. Natural gas flowing through the selected compressor stations is diverted to provide a high pressure first natural gas stream and a high pressure second natural gas stream. A pressure of the first natural gas stream is lowered to produce cold temperatures through pressure let-down gas expansion and then the first natural gas stream is consumed as a fuel gas for an engine driving a compressor at the compressor station. The second natural gas stream is first cooled with the cold temperatures generated by the first natural gas stream, and then expanded to a lower pressure, thus producing LNG.

Abstract: An apparatus and method for producing liquefied natural gas. A liquefaction plant may be coupled to a source of unpurified natural gas, such as a natural gas pipeline at a pressure letdown station. A portion of the gas is drawn off and split into a process stream and a cooling stream. The cooling stream passes through an expander creating work output. A compressor may be driven by the work output and compresses the process stream. The compressed process stream is cooled, such as by the expanded cooling stream. The cooled, compressed process stream is divided into first and second portions with the first portion being expanded to liquefy the natural gas. A gas-liquid separator separates the vapor from the liquid natural gas. The second portion of the cooled, compressed process stream is also expanded and used to cool the compressed process stream.

Abstract: A zero-emissions power plant receives natural gas from wells at elevated pressure and temperature. Gas is expanded through one or more turbo-expanders, preferably reformed, and sent to a fuel cell where electricity, heat, carbon-dioxide, and water are generated. The carbon-dioxide is compressed by at least one compressor and piped downhole for sequestration. The turbo-expanders have shafts which preferably share the shafts of the compressors. Thus, energy given up by the natural gas in the turbo-expanders is used to run compressors which compress carbon dioxide for downhole sequestration. In one embodiment, the natural gas is applied to heat exchangers in order to generate a stream of liquid natural gas. The remainder of the gas is expanded through the turbo-expanders and processed in the reformer prior to being sent to the fuel cell. A shifter may be used between the reformer and fuel cell. A solid oxide fuel cell is preferred.

A portion of the gas is drawn off and split into a process stream and a cooling stream. The cooling stream may pass through an expansion device.
