Útdráttur: The production of commercial liquid carbon dioxide (CO2) is an option for the utilization of the byproducts of geothermal power plants. Recovery of CO2 from non-condensable gases from geothermal fluids is the subject of this paper. A general description of the non-condensable gases found in different geothermal fields and their dependance on reservoir temperature is presented. The composition, quantities and the flow of non-condensable gases in the Miravalles Geothermal Field in Costa Rica is described. Case histories from Haedarendi, Iceland and Kizildere, Turkey geothermal fields are given as examples of actual CO2 production. Finally, the production process is analysed in two parts: the removal of H2S from the non-condensable gases and the CO2 recovery by liquefaction.
