Abstract
Disclosed are processes, apparatuses, and systems that can be used in natural gas pipelines to significantly reduce the CO2 emissions of the natural gas pipelines, by capturing combusted flue gas which is normally wasted and putting it back to the pipelines, which can also be monetized (e.g., carbon credits). One example process may include producing a captured CO2 stream from a combustion gas of a gas turbine in a natural gas pipeline, compressing the captured CO2 stream, and combining the compressed CO2 stream with natural gas transported in the natural gas pipeline.
