SUMMARY The present invention relates to a method for liquefying a methane-rich gas stream having a pressure greater than about 3103 kPa (450 psia). The gas stream is expanded to a lower pressure to provide a liquid having a gas phase and a temperature above about -112 ° C. (-170 ° F.) and a pressure sufficient that the resulting liquid product exists below its bubble point. And a product. The gas phase and the liquid phase are then separated in a suitable separator, and the liquid phase is charged to a storage means for storage at a temperature greater than about -112 ° C (-170 ° F). |
