Abstract
Patente de Invenção: <B>"PROCESSO E INSTALAçãO PARA SEPARAçãO DE AR POR DESTILAçãO CRIOGêNICA"<D>. Em um processo de destilação de ar, uma corrente de líquido pressurizado é vaporizada na linha de trocador principal (1) por troca de calor com ar ou nitrogênio. A refrigeração necessária é produzida por uma ou mais turbinas hidráulicas (9, 39) produzindo correntes compreendendo pelo menos 95% de líquido.
