Improvement of CO2 absorption and inhibition of NH3 escape during CaCO3 precipitation in the presence of selected alcohols and polyols

Abstrakt

This research aims to investigate the effect of selected organic substances containing hydroxyl groups on the reduction of NH3 escape and the improvement of CO2 capture during the precipitation of calcium carbonate by carbonation method using post-distillation liquid from the Solvay process and gas stream containing CO2 in the amount corresponding to the exhausted gases produced by the combustion of fossil fuels. Glycerol, ethylene glycol (EG), methanol, isopropanol, pentaerythritol, and neopentyl glycol (NPG) were used as ammonia escape inhibitors. The addition of NPG has been shown to result in the highest reduction of NH3 escape (83.1%) and the highest CO2 capture efficiency (86.1%). During the proposed CaCO3 precipitation with NPG, 98.7% of the NH3 initially introduced into the reaction mixture remains in the solution. Furthermore, the features that should be taken into account when introducing various alcohols and polyols for capturing NH3 and CO2 in the calcium carbonate precipitation via the carbonation method have been discussed.
