The production of precipitated calcium carbonate through the carbonation route presents a sustainable and efficient alternative to traditional mining methods.
Precipitation of calcium carbonate from a calcium
If calcium carbonate precipitated at 50 °C, the XRD results showed a mixture of calcite and vaterite regardless of the time at which the sample was taken. The morphology of calcium carbonate particles prepared at various conditions changed from calcite cubes to spherical particles of vaterite and aragonite needles.
CaCO3 production using liquid waste from Solvay method
It has to be stated that different branches of industry using calcium carbonate have different requirements for its purity, granulation, bulk density and other. The reported research focuses on obtaining calcium carbonate from the post-distillation liquid (DS) being a waste from the ammonia regeneration node of a Solvay method.
Sodium Carbonate
Sodium carbonate is now exclusively manufactured by the Solvay process. In this process carbon dioxide and ammonia are passed into a cold saturated solution of sodium chloride. In the reactions which occur sodium hydrogen carbonate is formed which is only very slightly soluble in the presence of sodium ions, is almost completely precipitated.
