Virtual gaseous fuel pipeline
Various embodiments provide an end-to-end gaseous fuel transportation solution without using physical pipelines. A virtual pipeline system and methods thereof may involve transportation of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), and/or adsorbed natural gas (ANG). An exemplary pipeline system may include a gas supply station, a mother station for treating gaseous fuels from the gas supply station, a mobile transport system for receiving and transporting the gaseous fuels, and user site for unloading the gaseous fuels from the mobile transport system. The unloaded gaseous fuels can be further used or distributed.
1. A system for transferring compressed gas from a gas supply to a destination storage vessel, the system comprising:
first and second flow paths each extending from the gas supply to the destination storage vessel, wherein the first and second flow paths diverge from each other downstream from the gas supply and then converge with each other upstream from the destination storage vessel;
a refrigeration unit operatively connected to the second flow path at a location between the divergence and convergence, wherein the refrigeration unit is configured to cool compressed gas within the second flow path; and
at least one valve configured to control which of the first and second flow paths is used to transfer compressed gas from the gas supply to the destination storage vessel,
wherein the at least one valve comprises an automated valve that is configured to shift from transferring a compressed gas along the first flow path to transferring compressed gas along the second flow path in response to a pressure of compressed gas in the destination storage vessel rising above a predetermined pressure.
2. The system of claim 1 , further comprising a compressor that is disposed in both the first and second flow paths.
3. The system of claim 1 , wherein the first flow path is an uncooled flow path.
4. The system of claim 1 , further comprising an uncooled storage vessel disposed in the first flow path.
5. The system of claim 1 , wherein the second flow path comprises a cooled storage vessel that is configured to be cooled by the refrigeration unit.
6. The system of claim 1 , wherein the at least one valve comprises an automated valve that is configured to shift from transferring a compressed gas along the first flow path to transferring compressed gas along the second flow path in response to a temperature of compressed gas in the destination storage vessel rising above a predetermined temperature.
