A gas pressurized separation system strips a product gas from a stream yielding a high pressure gaseous effluent containing the product gas such as may be used to capture CO.sub.2 from coal fired post combustion flue gas capture and to purify natural gas, syngas and EOR recycle gas. The system comprises a gas pressurized stripping column allowing flow of one or more raw streams in a first direction and allowing flow of one or more high pressure gas streams in a second direction, to strip the product gas into the high pressure gas stream and yield a high pressure gaseous effluent that contains the product gas. The process can further comprise a final separation process to further purify the product gas from the GPS column. For CO.sub.2 product, a preferred energy efficient final separation process, compound compression and refrigeration process, is also introduced.
