Diseño de un proceso para la obtención de cloruro de calcio a partir de piedra caliza en la Empresa INCOREG Cia. Ltda.

Abstract

For the production of calcium chloride from limestone, a process was designed at INCOREG CIA LTDA., located at the industrial park of Chimborazo province. The study consisted in choosing the right process for obtaining calcium chloride; treatability test were carried out obtaining dosage data on the raw material (limestone) and solvent (hydrochloride acid). Through a reactor prototype, heights were determined between reactants, and the reaction end point, in order to design the process by industrial equipment. The industrial process consists of: a jaw crusher, ball mill, two conveyor belts, dosing hopper, two batch reactors and two storage tanks. The final product was calcium chloride with a yield of 95%, obtained by the reaction of calcium carbonate and hydrochloride acid with a percentage of purity of 95% and 37% respectively, parameters referred to registration number in the American Chemistry Society (CAS) 100043-52-4(Calcium Chloride) where the density is 1.3 g/cm3, ph 8-9 representing a proportion of 35% calcium chloride. A feasibility study demonstrates that such design is feasible both economical and financially. According to the proposed Layout field study, one person is recommended for each job and once optimized, to perform a study of times and movements to identify the actual time in which the operator performs his activities.
