Process liquor carbonation and simulation on an industrial scale, harnessing exhaust gas from light diesel oil fired boilers in mining and ore processing plants.

​The release of flue gases is a widespread environmental issue in mineral processing operations. This flue gas contains several components i.e. CO2, CO, SO2, SO3, NO2, particulate, etc. Previously, trials were conducted on the usage of flue gas for the carbonation of process liquor generated from mineral processing industries at the batch level. Successful results and further modeling via MATLAB 2024 created the scope of further research on continuous trials for carbonation of process liquor. Experiments were conducted with proper arrangement for dipping flue gas into a reactor of approximately 200 L volume. Further analysis was done for Na2CO3, NaHCO3, and NaOH content before and after carbonation trials in batch mode. Modeling was done using MATLAB 2024 software after evaluating rate constants for main chemical reactions. These rate constant values may further be used to design suitable absorber columns on an industrial scale.
