The process of recovery, processing and purification of calcium carbonate generated by causticizing process (CaO + Na2CO3 + H2O - - amp; CaCO3 + NaOH + water) from the cellulose industry

摘要

The process of recovery, processing and purification of calcium carbonate generated by causticizing process (CaO + Na2CO3 + H2O, syn CaCO3 + NaOH + water) from the cellulose industry this patent application for invention refers to a process of recovery, processing and pur Ificau00e7u00e3o residue (CaCO3) generated in the production process of caustic soda (NaOH) in calcium carbonate precipitate.The industrial applicability of the CaCO3 PPT is mostly in the industries of paint, ceramics, rubber, steel, plastic, paper and cellulose. This procedure is to be used in place of the conventional process of production developed by the mining companies extract of soil to calcite.The product produced by the invention patent, has characteristics similar to the extracted from the conventional processes (mining), but has a much more accessible and provides a practical and feasible for disposal of waste generated by the industries of pulp.
