Beschreibung
Zusammenfassung:	The present invention relates to a biogas plant (10) including a fermenter (12), a biogas processing unit (16) and a thermal engine (14). The biogas processing unit (16) includes a gas separation unit (32) and a compression unit (33) for the separation of raw biogas (26) from the fermenter (12) into two gas streams, whereby the first gas stream (27) includes a product gas (28) that is enriched in biomethane (17) with respect to the composition of the raw biogas (26) and the second gas stream includes a residual gas (30) that is enriched with carbon dioxide with respect to the composition of the raw biogas (26). At least a fraction of the residual gas (30) is fed to the thermal engine (14), where energy (39) is produced that is used for operation of the compression unit (33).
