Abstract

"MéTODO E APARELHO PARA DESSULFURIZAçãO DE GáS RESIDUAL". O gás residual contendo óxido de enxofre é resfriado a uma temperatura de saturação de água ou superior e 80<198>C ou inferior em um aparelho de resfriamento de gás (3), e em seguida, introduzido em um recipiente de processo (4). O amónio aquoso é borrifado e injetado no gás residual de um bico de fluido duplo (12) no recipiente de processo (4), e o óxido de enxofre no gás residual é convertido em composto de amónio em pó e este mesmo composto é coletado por um aparelho de coleta (6). Quando o amónio aquoso é borrifado e injetado no gás residual, o amónio aquoso é pulverizado em gotículas com um diâmetro médio de Sauter de 0,5<109>m ou superior e 30<109>m ou inferior.
