Resumen
La presente investigación evalúa el potencial económico y medioambiental de la construcción y puesta en marcha de plantas de producción de cemento LC3 con mediano y pequeño formato, 300 000 tpa y 50 000 tpa. Primeramente, se realiza un diseño preliminar de las plantas debido a que no existen en el mundo actual con estas características. La herramienta analítica para la evaluación económica es la determinación del punto de equilibrio como técnica de análisis económico. Para el análisis medioambiental se compara la cantidad de kilogramos de CO2 por tonelada de cemento producida que generan estas plantas. Se demuestra que la planta de 300 000 tpa comienza a producir beneficios al 45.6 % de su capacidad con utilidades de 2 662 517, 63 USD y recupera su inversión a los 2 años. La planta de 50 000 tpa comienza a producir beneficios al 56.4 % de su capacidad con utilidades de 355 804,02 USD y recupera su inversión a los 4 años. Ambas plantas presentan una contribución a la reducción del impacto ambiental en un 38 %.
The present investigation evaluates the economic and environmental potential of the construction and start-up of LC3 cement plants with medium and small format, 300 000 tpy and 50 000 tpy. Firstly, a preliminary design of the plants is carried out because they do not exist in the present world with these characteristics. The analytical tool for economic evaluation is the determination of the break point as a technique of economic analysis. For the environmental analysis the amount of kilograms of CO2 per ton of cement produced by these plants is compared. It is shown that the 300,000 tpy plant starts producing profits at 45.6% of its capacity with profits of 2,662,517, 63 USD and recovers its investment after 2 years. The 50,000 tpy plant starts producing profits at 56.4% of its capacity with profits of 355 804.02 USD and recovers its investment at 4 years. Both plants have a contribution to the reduction of environmental impact by 38%.
