Resumo(s)
O processo de produção de cimento gera, inevitavelmente, a emissão de dióxido de carbono. Além disso, a produção de clínquer requer fornecimento de calor, o que, historicamente, tem sido feito por meio de combustíveis fósseis. A política climática da União Europeia estabeleceu a obrigação de neutralidade de carbono para a indústria cimenteira até 2050. Com base nisso, a Cembureau apresentou um plano para substituir os combustíveis fósseis por alternativas. Em Portugal, a Secil desenvolveu o Projeto CCL - Clean Cement Line, com o objetivo de realizar o revamping de uma linha existente e a instalação de um calcinador com uma câmara de combustão para queima de combustíveis mais grosseiros em substituição aos fósseis. A linha agora opera com uma taxa de 85% de combustíveis alternativos (sendo 70% derivados de resíduos), um aumento de 30% em relação ao projeto anterior. Em função dessas mudanças, a estratégia e a logística de combustíveis na Secil foram repensadas. Identificou-se a necessidade de aumentar a capacidade de abastecimento do principal armazém da empresa para suprir o maior consumo decorrente do projeto. Assim, foi instalada e programada uma linha de abastecimento adicional, duplicando a capacidade existente. Com o aumento no consumo de Combustíveis Derivados de Resíduos, a garantia da qualidade desses materiais também se tornou mais importante. Nesse contexto, a tecnologia Near-Infrared foi identificada como uma opção promissora para medir o poder calorífico inferior desses combustíveis em tempo real.
Cement production process inevitably generates carbon dioxide emissions. Furthermore, clinker production requires a heat supply, which historically has been accomplished through the use of fossil fuels. The European Union's climate policy has established the obligation of carbon neutrality for the cement industry by 2050. Based on this, Cembureau has presented a plan to replace fossil fuels with alternatives. In Portugal, Secil has developed the CCL (Clean Cement Line) Project, aiming to revamp an existing line and install a calciner with a combustion chamber to burn coarser fuels as a substitute for fossil fuels. The line now operates with an 85% rate of alternative fuels (with 70% derived from waste), a 30% increase compared to the previous project. Due to these changes, Secil's strategy and logistics regarding fuel have been redone. The need to increase the supply capacity of the company's main warehouse to meet the higher consumption resulting from the project was identified. Therefore, an additional supply line was installed and programmed, effectively doubling the existing capacity. With the increased consumption of Waste-Derived Fuels, ensuring the quality of these materials has also become more important. In this context, Near-Infrared technology has been identified as a promising option for real-time measurement of the lower heating value of these fuels.
