Process for obtaining precipitated calcium carbonate with use of steam and carbon dioxide in the blast furnace pig iron

摘要

The process of briquetting of heat curing components generated in the waste siderurgicos or minerals. The present invention patent is a process of obtaining PCC (precipitated calcium carbonate) with the use of surplus steam and carbon dioxide (CO2) from a blast furnace pig iron.Consists of the use of excess heat generated in the external source (blast furnace pig iron), who once directed to a recovery boiler generates steam necessary for the drying of the CCP.Carbon dioxide (CO2) with high concentration which is dispersed in the atmosphere will be used in the process of carbonation depth, which is the transformation of calcium hydroxide (Ca (OH) 2) on calcium carbonate precipitate. The present invention resets the manufacturing process of the CCP.
