Abstract:
1. A process comprising: obtaining produced gas from a source of produced gas, said produced gas including at least one hydrocarbon gas and at least one waste gas; supplying an inlet system for dehydrating the produced gas; supplying a heat exchanger to cool produced gas after dehydration; supplying a gas processing system for separating gases of the produced gas after cooling; supplying said produced gas to said inlet system and operating said inlet system to dehydrate the produced gas and form dehydrated produced gas; supplying said dehydrated produced gas to said heat exchanger to cool said dehydrated produced gas to form at least one waste liquid from at least one waste gas and to form cooled dehydrated produced gas having at least one at least one waste liquid entrained therein; supplying said cooled dehydrated produced gas with entrained at least one waste liquid to a gas processing system and operating said gas processing system to separate said cooled dehydrated produced gas into at least a hydrocarbon stream and said waste liquid, said hydrocarbon stream including at least carbon dioxide gas and methane and said waste liquid including at least carbon dioxide liquid; processing said hydrocarbon stream to separate said carbon dioxide gas and said methane, returning said carbon dioxide gas for incorporation with dehydrated gas and supplying said methane as an hydrocarbon output; supplying pressurizing means for pressurizing a stream; operating said pressurizing means to pressurize said waste liquid; supplying said waste liquid under pressure to an injection well; and injecting said waste liquid into said injection well.
