Abstract

"PRODUçãO DE ARGÈNIO COM UM SISTEMA DE TRêS COLUNAS PARA DECOMPOSIçãO DO AR E UMA COLUNA DE ARGÈNIO BRUTO". O processo e o dispositivo servem para produção de argónio com um sistema de três colunas para decomposição do ar, que apresenta uma coluna de alta pressão (11), uma coluna de baixa pressão (13) e uma coluna de média pressão (12). Uma primeira corrente de ar de insumo (10, 64) é introduzida na coluna de alta pressão (11) e ali separada em um primeiro líquido enriquecido em oxigênio e um primeiro gás de topo de nitrogênio. Uma primeira fração enriquecida em oxigênio (23, 24, 26) da coluna de alta pressão (11) é introduzida na coluna de média pressão (12) e ali separada em um segundo líquido enriquecido. Uma segunda fração enriquecida em oxigênio (33, 35) da coluna de alta pressão e/ou da coluna de média pressão (12) é introduzida na coluna de baixa pressão (13) e ali separada em um terceiro líquido enriquecido em oxigênio e um terceiro gás de topo de nitrogênio. Uma fração contendo argónio (68) da coluna de baixa pressão (13) é introduzida em uma coluna de argónio bruto (70) e ali separada em uma fração de topo de argónio bruto e um líquido rico em oxigênio. Ao menos uma parte (73) da fração de topo de argónio bruto (71) é conduzida a um condensador de argónio bruto (29) e ali ao menos parcialmente condensada por troca de calor indireta com ao menos uma parte (27) do segundo líquido enriquecido em oxigênio da coluna de média pressão (12). Vapor (32) enriquecido em oxigênio então formado é reconduzido à coluna de média pressão (12). Uma fração (72) da região superior da coluna de argónio bruto (70) e/ou uma parte da fração de topo de argónio bruto é obtida a jusante do condensador de argónio bruto como produto de argónio bruto.
