Zusammenfassung:	THE INVENTION PROVIDES A PROCESS AND A DEVICE FOR REMOVING GASEOUS CONTAMINANTS FROM A FEED GAS STREAM WHICH COMPRISES METHANE AND GASEOUS CONTAMINANTS, IN WHICH PROCESS THE TEED GAS STREAM IS COOLED TO OBTAIN A SLURRY WHICH COMPRISES SOLID CONTAMINANT, LIQUID PHASE CONTAMINANT AND A METHANE ENRICHED GASEOUS PHASE, THE SLURRY SO OBTAINED IS INTRODUCED INTO A CRYOGENIC SEPARATION DEVICE (4) IN WHICH FROM THE TOP THE METHANE ENRICHED GASEOUS PHASE IS REMOVED (5), THE SLURRY IS DILUTED WITH LIQUID PHASE CONTAMINANT (6) AND INTRODUCED AS SUCTIOR.FLUID INTO AN EJECTOR (9) VIA WHICH IT IS PASSED INTO A HEAT EXCHANGER (10) ARRANGED OUTSIDE THE SEPARATION DEVICE AND WHEREIN SOLID CONTAMINANT IS MELTED INTO LIQUID PHASE CONTAMINANT, PART OF THE LIQUID PHASE CONTAMINANT SO OBTAINED IS RECYCLED (6) TO DILUTE THE SLURRY OF CONTAMINANTS INSIDE THE SEPARATION DEVICE AND PART (13) IS INTRODUCED INTO THE BOTTOM PART OF THE SEPARATION DEVICE, LIQUID PHASE IS WITHDRAWN (14) FROM THE BOTTOM PART OF THE SEPARATION DEVICE, AND PART OF THE WITHDRAWN LIQUID PHASE CONTAMINANT IS RECOVERED AS A STREAM PROAUCT (16) AND PART IS RECYCLED (17) TO THE EJECTOR FOR USE A MOTIVE FLUID.
