Absorption of combustion gases in boron solutions and recovery as industrial products

• Obtained sodium (Na) % recovery yield was between 12.8% and 23.8%.
• Experiments was carried out at 12.71 solid/liquid rate, 20–700 psi range, 600 psi, between 1 and 6 h.
• The most suitable reaction time was recorded as 2 h.
• The production of the product that contains NaHCO3 and boron together as the raw materials used in glass industry.

In this study, it is aimed that to reduce environmental effects of CO2 (as a greenhouse gas), to achieve absorption of CO2 in boron solutions and to yield a mixture product with boron compounds and the NaHCO3 which is raw material input especially in glass industry. In the laboratory scale experiments using autoclave, with different pressure, solid/liquid ratio, and different reaction times, absorption of CO2 in the boron solutions were examined and the Na-borate compounds containing NaHCO3 were produced. The characterization of the products was determined by XRD inspections and chemical analysis. In the studies, maximum 92.4% NaHCO3 bearing borate compounds was obtained. As a result of the purification of these products it was reached pure NaHCO3 by 99%.
