Coprocessamento de pneus inservíveis e sua relação com as emissões atmosféricas de NOx em fábrica de cimento

Abstract

The shredded tire "Unworkable" is a solid waste that needs to be managed in a way correct, give the disposal process of milling, storage, disposal and transport use in the process of Co-processing in Cement Factory, because when you don't performed all the steps correctly, can cause damage to the environment and public health. The use of shredded tire "Unworkable" in the city of Cuiabá MT in Cement Factory, began in the year 2014, through partnerships with recycling companies in the States of Mato Grosso and Mato Grosso do Sul, which consists of the collections of the tires along the customers, milling procedure until your target of co-processing for use in clinker kilns for replacement of petrochemical origin waste heat. The study was conducted at the factory located at Votorantim Cimentos Highway MT401-KM14 .4-Fazenda Bela Vista Countryside, District of Aguaçu, London. The methodology used in the study was based on a qualitative assessment of the legal parameters of COMANA, resolutions N° 264 of 1999, CONAMA, N° 258 of 1999 and COMANA, no. 382 of 2016 and quantitative assessment of the results presented atmospheric emissions of co-processing and NOx emissions through the use of coke-oven oil ground clinker. The result presented by using shredded tire "Unworkable" in Coprocessing, demonstrating that the feed rate in a range of 2.5 to 3t/h NOx is shot down and stay within legal parameters, determining a rate of food great, causing NOx emissions remain below the tolerance limit, pursuant to resolution CONAMA No. 382, 2006.
