Resumen
A partir de la situación actual de la industria azucarera cubana es que se hace necesario un análisis de mejoras tecnológicas y operacionales que garanticen una mayor rentabilidad de esta industria en el país. En el presente trabajo se realiza el análisis de alternativas de la Empresa Azucarera “Antonio Sánchez” del poblado de Covadonga, Cienfuegos; con el fin de mejorar las condiciones del central. Se realizó una búsqueda bibliográfica relacionada con el tema, a fin de alcanzar un mayor conocimiento relacionado situación de la caña de azúcar y la industria azucarera en Cuba y a nivel mundial. Se identificó la instalación de estudio y se determinaron los balances de masa y energía para las condiciones actuales, en las que a partir de 3 680 t/d de caña de azúcar se obtienen 404,16 t/d de su producto principal, azúcar. A partir
de los resultados alcanzados se propusieron mejoras, se valoraron dos alternativas: una inversión inicial para montar un turbo de extracción-condensación y una caldera de alta presión y la segunda desviando el jugo de los filtros del central, para introducirlo al proceso fermentativo de obtención de alcohol en la destilería, en ambas se aumentó la capacidad de molienda a 4 500 t/d. Se realizó el análisis económico de cada una de ellas por separado, auxiliándose en Microsoft Excel, donde resultó la alternativa 3 la más económicamente viable, con un VAN de $17 455 980,54, una TIR de 54 % y un PRD de 3,3 años.
From the present situation of the Cuban sugar industry is that an analysis of technological and operational improvements to ensure greater profitability of this industry in the country is necessary. In this paper is performed the analysis of alternatives Sugar Enterprises "Antonio Sanchez" in the village of Covadonga, Cienfuegos; in order to improve the conditions of the central. A literature search related topic was made in order to achieve a better knowledge of the situation associated with sugar cane and sugar industry in Cuba and worldwide. Installing study was identified and mass and energy balances were determined for the current conditions, which from 3680 t / d of sugar cane are obtained 404.16 t / d of its main product, sugar. From the results achieved improvements were proposed, two alternatives were evaluated: an initial investment to be put on a extraction-condensing turbo and high pressure boiler and the second deflecting juice filters center to enter the fermentation process obtaining alcohol distillery in both milling capacity to 4,500 t / d was increased. Economic analysis of each of them separately, with the help in Microsoft Excel, where Alternative 3 was the most economically viable, with an NPV of $17 455 980,54 , an IRR of 54% and 3,3 PRD was performed two years.
