Abstract

Este trabajo pertenece a la rama química, específicamente a la obtención de yeso de alta pureza para su aplicación en la industria médico- farmacéutica, específicamente para la producción de vendas enyesadas. El yeso se obtiene a partir de dos residuales industriales que proporcionan el sulfato y el calcio respectivamente. La fuente de sulfato es la salmuera residual de la industria salinera marina y la de calcio, el hidróxido de calcio contenido en el cieno que se genera como subproducto de la producción del acetileno. La esencia del invento consiste en mezclar el cieno con la salmuera residual en proporciones definidas para precipitar todo el magnesio y sulfato contenido en la misma con la finalidad de obtener una solución rica en cloruro de calcio, la cual posteriormente se mezcla con una nueva cantidad de salmuera residual produciéndose un yeso de alta pureza. El procedimiento permite aprovechar las potencialidades que tienen ambos desechos: la salmuera, un licor rico en sulfatos solubles que fueron concentrados por la acción solar y el cieno, un lodo que contiene una elevada concentración de calcio en forma de hidróxido y que se produce debido a la descomposición del carburo durante la obtención de acetileno. Aplicando este esquema se reducen sensiblemente los costes para la obtención de un producto de alto valor agregado. Además, como el yeso que se sintetiza tiene una gran pureza, es indeleble al tacto y muy blanco, constituye una excelente materia prima para la producción de hemidrato utilizable en la industria médico- farmacéutica, específicamente para la producción de vendas enyesadas.This work belongs to the chemical branch, specifically to obtain high purity plaster for its application in the medical-pharmaceutical industry, specifically for the production of plastered bandages. Plaster is obtained from two industrial residuals that provide sulfate and calcium respectively. The source of sulfate is the residual brine from the marine salt industry and calcium, the calcium hydroxide contained in silt that is generated as a byproduct of acetylene production. The essence of the invention consists in mixing the silt with the residual brine in defined proportions to precipitate all the magnesium and sulfate contained therein in order to obtain a solution rich in calcium chloride, which is subsequently mixed with a new amount of residual brine producing a high purity plaster. The procedure allows taking advantage of the potential of both wastes: brine, a liquor rich in soluble sulfates that were concentrated by solar action and silt, a sludge that contains a high concentration of calcium in the form of hydroxide and is produced due to Carbide decomposition during acetylene. Applying this scheme significantly reduces the costs of obtaining a product with high added value. In addition, since the plaster that is synthesized has a high purity, it is indelible to the touch and very white, it constitutes an excellent raw material for the production of hemidrate that can be used in the medical-pharmaceutical industry, specifically for the production of plastered bandages.
