Abstract
The invention relates to a system and method of treating a flow back fluid exiting a well site following stimulation of a subterranean formation. The invention utilizes a two-stage membrane process during the period that the gas contains high concentrations of COby volume, and allows for separation of COfrom the natural gas components, providing pipeline-quality natural gas (approximately 5% COby volume) to the gas collection system.
