A liquefied natural gas production and storage scheme for offshore liquefaction of stranded gas reserves using a processing vessel and a liquefaction and storage shuttle vessel. The processing vessel includes the typical steps of condensate management, pre-treatment and compression. The processing vessel also recompresses a recycle gas from the LNG production and storage vessel. The high pressure, treated natural gas is fed to the LNG production and storage vessel that has minimal processing equipment consisting of at least a heat exchanger, an isentropic expander, a separator vessel, and a small LP compressor. The liquefier on the liquefaction and storage vessel are designed to generate a high liquid yield without the need for excessive operating pressures or multiple refrigerants circulating between vessels. |
