Abstract

"PROCESSO E DISPOSITIVOS PARA A PRODUçãO DE NAFTALINA DE GáS BRUTO DE FORNO ALIMENTADO POR COQUE". Processo para a produção de naftalina de gás bruto de forno alimentado por coque no qual o gás bruto de forno alimentado por coque é refrigerado diretamente com água de irrigação e no qual a naftalina é obtida pela refrigeração subseq³ente e por um processo de tratamento, sendo que o gás bruto de forno alimentado por coque, depois da refrigeração direta do gás bruto de forno alimentado por coque, é conduzido através de um filtro eletrostático e, em seguida, é refrigerado de tal maneira que a naftalina contida no gás bruto de forno alimentado por coque é precipitada da fase gaseiforme e é obtida sem outro processo de tratamento como naftalina pura.
