Diseño de un Crudo que Permita la Utilización de Neumáticos Usados como Combustible Alternativo en la Empresa Cemento Chimborazo

Abstract

To design a crude oil (limestone and clay mixture) that allows the use of used tires as an alternative fuel in the company Cemento Chimborazo C.A. The analytical method used was based on the characterization of the tire through a complexometric analysis to determine the main mineral components present in the tire. It was determined from an experimental method, that the dosage of crude oil and tire ashes through the design calculation from its hydraulic modules was not adequate since it does not meet the expectations required by the company, therefore the proposed dosage is 99%, 98%, 97% of crude oil and 1%, 2%, 3% of tire ashes respectively. The method used for the elaboration of clinker was evaluated by microscopy analysis. The project was carried out in the company's quality control laboratory, using materials such as: X-ray spectrometer, microscopy equipment, press, ball mill. According to the chemical analysis for the cement obtained with 1% ash, free lime values of 1.00, SC modulus of 92.2, MS of 2.80 and MA of 1.73 were obtained, in addition to an alkali ratio of 0.56. These data are within the company's internal norm. It was concluded that the optimum dosage is the one containing 1% of ashes from used tires and 995 of crude oil. It is recommended to incorporate 1% of used tires to the kiln, since an increase in this could cause negative effects in the clinkering process.
