Keywords: | CO2 absorption enthalpies of absorption densities alkanolamines |
Abstract (eng): | The capture of carbon dioxide from post-combustion emission is one of the challenges for reducing the release of greenhouse gases into the atmosphere. It is a mature technology but studies are still needed particularly in order to reduce gas treatment costs. In the present work, densities and enthalpies of absorption of CO2 in aqueous solutions of several systems of alkanolamines were measured at 298,15K. The experiments were carried out using a flow mixing calorimetric technique (Setaram C80) that permits measuring enthalpies of absorption of CO2 in a sorbent solution as a function of loading charge (moles of CO2 per mole of amine). Measurements were performed by increasing the loading charge up to the saturation of the solution. Saturated loading point can be determined from the experimental enthalpy data and the values of enthalpies of absorption were found independents of the amine concentration. Experimental enthalpies and densities data were compared with literature values. |
