A Potential Remotion Process and Utilization of the Non-Condensable Gases CO2 and H2S from the Geothermal Wells in Cerro Prieto

Abstract

A remotion process of CO2, and H2S is proposed at the theoretical level, as an alternative to eliminate those gases and utilize them to obtain in the end, useful by products. The method is based initially on the reaction between the CO2 contained in the noncondensable gases and the alka nolamine which selectively strips out the gas in an absorption tower, leaving the rest of the noncondensable current with a high content of H2S, which then could be treated with an inorganic compound in a reactive chamber. Both reactions give rise to material that with further treatment could lead to commercial products such as liquefied CO2 and CaS.
