Description: Das Projekt "Entwicklung von stationaeren Traegermembranen (FSCM) fuer selektive Kohlendioxidabscheidung aus Gasstroemen" wird vom Umweltbundesamt gefördert und von GKSS-Forschungszentrum Geesthacht, Standort Geesthacht, Institut für Chemie durchgeführt. The separation of carbondioxide from gas streams is an important industrial separation process. Applications which are relevant to the project proposed here are: carbondioxide separation from methane (natural gas sweetening, enhanced oil recovery, landfill gas treatment), carbondioxide/hydrogen-separation (coal gasification process, steam reforming of hydrocarbons), carbondioxide/nitrogen-separation (flue gas treatment), carbondioxide separation in life support systems (diving chambers, space crafts), medical applications (carbondioxide removal from nitrous oxide or xenon in the anaesthesia gas loop). The objective of this project is the development of novel membranes with very high selectivities for carbondioxide. The carbondioxide selectivity in regard to other gases like nitrogen, oxygen, methane, hydrogen and nitrous oxide should exceed 200. The fluxes to be achieved should be high enough to render the membrane process competetive with conventional separation processes. The minimum carbondioxide flux to be aimed at is 0,05 m3/m2h bar.
