Abstract

SISTEMAS E MÉTODOS PARA IMPEDIR REAÇÕES DE TERMITA EM CÉLULAS ELETROLÍTICAS. A presente invenção refere-se a um método de monitorar uma célula eletrolítica que inclui detectar informação indicativa de uma reação de termita, comparar a informação indicativa de uma reação de termita a um limiar, gerar um sinal de resposta de termita de acordo com a comparação, e reagir ao sinal de resposta de termita com o ajuste da operação da célula eletrolítica.
