METHOD AND SYSTEM FOR CO2 REJECTION WITH A TWO STAGE MEMBRANE PROCESS

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 C02 by volume, and allows for separatio...

Beschreibung
Zusammenfassung:	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 C02 by volume, and allows for separation of C02 from the natural gas components, providing pipeline-quality natural gas (approximately 5% C02 by volume) to the gas collection system La présente invention concerne un procédé et un système de traitement d'un fluide de retour sortant d'un site de puits après la stimulation d'une formation souterraine. L'invention met en uvre un procédé à membrane à deux étages pendant la période où le gaz contient des concentrations élevées de CO2 par volume, et permet de séparer le CO2 des constituants de gaz naturel, de sorte à fournir du gaz naturel de réseau de transport (approximativement 5 % de CO2 en volume) au système de collecte de gaz.
