Abstract
"PROCESSO E APARELHAGEM PARA PRODUçãO DE OXIGêNIO DE PUREZA MODERADA E DE NITROGêNIO DE PUREZA MODERADA POR MEIO DE SEPARAçãO CRIOGêNICA DE AR". Um sistema de separação criogênica de ar no qual ar de alimentação é inicialmente processado para produzir um vapor e um líquido, o vapor é então processado na seção de retificação de um condensador de refluxo para produzir nitrogênio de pureza moderada, e o líquido é processado na seção de extração do condensador de refluxo para produzir oxigênio de pureza moderada.
