Abstract
The present invention describes a process for capturing COusing an optimized mixture of water and alcohols with alkali hydroxides, such as KOH and NaOH, for absorption of COfrom gaseous mixtures. The process shows high efficiency and low volatility and corrosivity rate of the solvent, in addition to allowing cost reduction for installation and maintenance of reactors and reducing solvent loss. The present invention also describes a process for regenerating solvent or its reuse, carried out by chemical precipitation, continuously and not in batch, through the reaction with alkaline earth oxides, such as CaO and MgO, and/or alkaline earth hydroxides, such as Ca(OH)and Mg(OH), for the formation of carbonates, such as CaCOand MgCO, which can be discarded in nature without any environmental issue or can be used commercially in industry or agriculture.
