A process for pretreating a natural gas stream having greater than about 40 mole % CO 2 to reduce the amount of CO 2 in the gas stream prior to treatment in a conventional sweetening process comprising passing the gas stream through a separator zone which condenses the C 6 plus hydrocarbons and then passing the gas stream from the separator into a stripping zone which further reduces the temperature of the gas stream to remove a substantial quantity of CO 2 as a liquid condensate.

1. A process for pretreating a natural gas stream having greater than about 40 mole % carbon dioxide to remove therefrom a substantial quantity of the carbon dioxide as a high pressure liquefied product stream, comprising the steps of: passing said gas stream through a separator zone at a temperature of from about 30° to about 80° F. while said gas stream is maintained at a pressure of from about 600 psia to about 1200 psia to remove from said gas stream as a liquid condensate those gas components which are condensible at said temperature and pressure; removing the liquid condensate from the separator zone; feeding the gas stream from the separator zone through a stripping zone at a temperature of from about -20° to about 0° F. while maintaining said gas stream at a pressure of from about 600 psia to about 1200 psia to remove from said gas stream a substantial quantity of the carbon dioxide content as liquefied carbon dioxide. 2. The process of claim 1, wherein the liquefied carbon dioxide removed has a temperature from about 30° to about 80° F. and a pressure of from about 600 psia to about 1200 psia. 3. The process of claim 1, wherein the volume of the gas stream exiting the stripping zone is 20 to 60% less than the volume of the natural gas stream passing into the separator zone. 4. The process of claim 1, wherein the carbon dioxide content of the gas stream exiting the stripping zone ranges from about 30 to about 50 mole percent. 5. The process of claim 1, wherein the natural gas stream has less than about 90 mole % carbon dioxide. 6. The process of claim 1, wherein the separator zone comprises more than one separation vessel. 7. The process of claim 1, wherein the stripping zone comprises a packed or trayed stripper column. 8. The process of claim 1, further comprising processing said gas stream from said stripping zone in a cryogenic sweetening process wherein the carbon dioxide content of said gas stream is further reduced. 9. The process of claim 1, further comprising processing said gas stream from said stripping zone wherein additional carbon dioxide in said gas stream is absorbed by a solvent. 10. A process for pretreating a natural gas stream having from about 40 to about 90 mole % carbon dioxide to remove therefrom a substantial quantity of the carbon dioxide as a high pressure liquefied product stream, comprising the steps of: passing said gas stream through a separator zone at a temperature of from about 30° to about 80° F. while said gas stream is maintained at a pressure of from about 600 psia to about 1200 psia to remove from said gas stream as a liquid condensate those gas components which are condensible at said temperature and pressure; removing the liquid condensate from the separator zone; feeding the gas stream from the separator zone through a stripping zone at a temperature of from about -20° to about 0° F. while maintaining said gas stream at a pressure of from about 600 psia to about 1200 psia to remove from said gas stream a substantial quantity of the carbon dioxide content as liquefied carbon dioxide, thereby reducing the carbon dioxide content of the gas stream exiting the stripping zone to a range from about 30 to about 50 mole percent. 11. The process of claim 10, wherein the liquefied carbon dioxide removed has a temperature from about 30° to about 80° F. and a pressure of from about 600 psia to about 1200 psia. 12. The process of claim 10, wherein the volume of the gas stream exiting the stripping zone is 20 to 60% less than the volume of the natural gas stream passing into the separator zone. 13. The process of claim 10, wherein the separator zone comprises more than one separation vessel. 14. The process of claim 10, wherein the stripping zone comprises a packed or trayed stripper column. 15. The process of claim 10, further comprising processing said gas stream from said stripping zone in a cryogenic sweetening process wherein the carbon dioxide content of said gas stream is further reduced. 16. The process of claim 10, further comprising processing said gas stream from said stripping zone wherein additional carbon dioxide in said gas stream is absorbed by a solvent.
