Abstract

Sometemos el carbonato cálcico a proceso de trituración (1).#Y en saturadora a disolución el dióxido de carbono en agua (2). El agua, con el ácido carbónico disuelto, pasa a un tanque de reacción (3) junto con el carbonato cálcico triturado. Y mediante agitación suave, se forma bicarbonato cálcico, que queda disuelto en el agua, se filtra (7) y pasa a otro depósito de reacción (4), y se desprende dióxido de carbono, que llevamos a depósito de almacenamiento (5). El bicarbonato cálcico que estaba en la disolución, al desprenderse el dióxido de carbono, precipita en forma de carbonato cálcico de alta pureza y mínima granulometría en este depósito (4). El agua, es recogida y previa filtración (6) la recirculamos (8) a la saturadora para reiniciar el proceso. El mismo modo, el dióxido de carbono, almacenado (5), se recircula para reutilizarlo.We subject the calcium carbonate to crushing process (1). # And in saturating solution the carbon dioxide in water (2). The water, with the dissolved carbonic acid, passes to a reaction tank (3) together with the crushed calcium carbonate. And by gentle agitation, calcium bicarbonate is formed, which is dissolved in the water, filtered (7) and passed to another reaction tank (4), and carbon dioxide is released, which we take to storage tank (5). The calcium bicarbonate that was in the solution, upon release of carbon dioxide, precipitates in the form of calcium carbonate of high purity and minimal granulometry in this tank (4). The water is collected and after filtration (6) we recirculate it (8) to the saturator to restart the process. In the same way, the carbon dioxide, stored (5), is recirculated for reuse.
