Abstract

MéTODO PARA O PROCESSAMENTO DE GASES RESIDUAIS EM um método para o processamento de gases residuais, os gases residuais provenientes de uma instalação de incineração para gases não condensáveis de um moinho de polpa Kraft são lavados por meio de um composto de cálcio. O composto de cálcio é lama de cal retirada da recirculação de substância química do moinho de polpa Kraft depois da caustificação e antes de um forno de requeima de cal e é usado na lavagem de gás como uma substância que reage com o dióxido de enxofre.
