Abstract

"DESENVOLVIMENTO EM APARELHO E MéTODO PARA OXIDAçãO DE LODO DE EFLUENTE LìQUIDO NãO DIGERIDO". Tal como definido nas reivindicações de 1 a 21 do pedido de patente PI9809300-2, sendo o aparelho desenvolvido compreendido por um separador conectado para receber um efluente do sistema supercrítico de tratamento de oxidação de água e separar um efluente sólido carregado por meio disso, e um trocador de calor conectado para receber um fluxo de alimentação para um sistema supercrítico de tratamento de oxidação de água em uma troca de calor relacionada com o efluente sólido carregado e para adicionar calor ao fluxo de alimentação a partir do efluente sólido carregado. O Método desenvolvido compreendido pela inclusão das etapas de: recebimento de um efluente de um sistema supercrítico de tratamento de oxidação de água e separação de um efluente sólido carregado de um efluente fluído limpo, o efluente sólido carregado compreendendo solidez em um fluído; e aquecimento de um fluxo de alimentação para o sistema supercrítico de tratamento de oxidação de água pela troca de calor com o efluente sólido carregado.
