Abstract
Methods for extracting and compressing an inert gas from an exhaust gas of an engine relate to providing an inert gas processing system including a multi-stage gas compressor to receive the exhaust gas from an exhaust gas processing system, a cooling and extraction system to receive the exhaust gas from each stage of the multi-stage gas compressor and remove liquids from the exhaust gas, and a controller to monitor operation of the inert gas processing system. The methods include processing the exhaust gas before each stage of the multi-stage gas compressor to clarify the inert gas in the exhaust gas, processing the exhaust gas after each stage of the multi-stage gas compressor to clarify the inert gas in the exhaust gas and compressing the inert gas processed for export from the inert gas processing system.
