Abstract (en)

A plant for liquefying methane gas, comprising: a power section (100) comprising: a molecular filter (2) supplied by a low-pressure methane supply network (1), a compression unit (5) of the methane, connected to the outlet of the filter, destined to supply in outlet a methane main flow (¦) having a predetermined temperature and pressure, and heat exchangers (11, 12, 13, 14) for cooling the methane crossing the compression unit (5); a first cryogenic section (200) connected to the outlet of the power section (100) by which it is supplied from the main flow (Æ) and, in turn, supplying the power section (100) with at least a methane recycling flow (Æ 2 , Æ 4 , Æ 7 ), which supplies the compression unit and which cooperates with the heat exchangers for cooling the compression unit; a second cryogenic section (300) connected to the first cryogenic section (200) in inlet and in outlet by means of channels (19, 22, 24) crossed by the relative methane flows (Æ 1 , Æ 4 , Æ 7 ), the second cryogenic section (300) being destined to liquefy a predetermined amount of the main flow (Æ); a storage cryogenic section (400) connected to the second cryogenic section (300) so as to receive therefrom the liquefied methane.
