<p>Method for liquifying natural gas comprising regulating (24) the pressure of the natural gas from a pressure ranging from 0 - 25 psig. Contaminants are filtered out (28) of the regulated gas. The natural gas is then compressed (36) to a higher pressure. At least a one-stage heat exchange is performed with the compressed natural gas by utilizing a coolant to provide a cooled compressed natural gas. A Joule Thomson valve is used to liquify at least a portion of the cooled compressed natural gas. The liquified natural gas is stored in a dewar (78). Unliquified natural gas passing from from the dewar (78) is utilized to provide cooling of the natural gas during the heat exchange. The unliquified gas is then recompressed. The recompressed natural gas is subjected to the same steps to liquify an additional portion of the recompressed natural gas.</p> |
