Abstract

"PROCESSO E APARELHAGEM PARA A REALIZAçãO DE SEPARAçãO CRIOGêNICA DE AR". Um sistema de separação criogênica de ar no qual uma porção do ar de alimentação é comprimida para uma pressão muito elevada, é desviada do trocador de calor primário, e é turboexpandida para uma pressão baixa para fornecer refrigeração em uma etapa desde a temperatura da extremidade quente até a temperatura criogênica de separação criogênica de ar.
