Abstract

"PROCESSO PARA RECUPERAR HéLIO" Esta invenção refere-se a um processo para recuperar hélio. O processo compreende a) passar um primeiro gás contendo hélio (10) em um ejetor (26) para produzir um segundo gás (28); b) passar o segundo gás (28) através de um trocador de calor (40) para produzir um terceiro gás; c) recuperar o terceiro gás (42) para dentro do ejetor (26) para combinar com o primeiro gás (10).
