Abstract
PROCESSO DE SEPARAçãO DE AR A BAIXA TEMPERATURA PARA PRODUZIR PRODUTO GASOSO PRESSURIZADO. Uma corrente de ar comprimido (1) é esfriada em um trocador (65) para formar uma corrente de ar comprimido esfriado (5) A corrente é em seguida comprimida de modo criogênico em um primeiro compressor (50) para formar uma primeira corrente de gás pressurizado. A primeira corrente de gás pressurizado é ainda mais esfriada no trocador, comprimida de modo criogênico em um segundo compressor e em seguida é esfriada e parcialmente liquefeita. O produto estriado e parcialmente liquefeito (56) é em seguida fornecido a um sistema de colunas de destilação (80, 81) é removido um produto líquido (20) do sistema de colunas de destilação (80, 81). Este produto é em seguida pressurizado (21), vaporizado e aquecido no trocador (65) para produzir produto gasoso pressurizado (22). O sistema de colunas de destilação é alimentado com uma corrente líquida de alimentação obtida do ar.
