Abstract
"PROCESSO E APARELHO PARA SEPARAçãO DE AR POR MEIO DE DESTILAçãO CRIOGêNICA". Trata-se de um processo para separar are por meio de destilação criogênica em um sistema de coluna que compreende uma coluna de alta pressão e uma coluna de baixa pressão compreende comprimir todo o ar de alimentação em um primeiro compressor (1) até uma primeira pressão de saída, enviar uma primeira parte do ar na primeira pressão de saída até um segundo compressor (3) e comprimir o ar até uma segunda pressão de saída, resfriar pelo menos parte do ar na segunda pressão de saída em um expansor de calor (5) para formar ar comprimido resfriado na segunda pressão de saída, enviar pelo menos parte (7) do ar comprimido resfriado na segunda pressão de saída até um terceiro compressor (8) e comprimir pelo menos parte do ar comprimido resfriado na segunda pressão de saída até a terceira pressão de saída, liquefazer pelo menos parte do ar na terceira pressão de saída e enviar o ar liquefeito (10) até pelo menos uma coluna do sistema de coluna, onde pelo menos 50% do ar liquefeito enviado para o sistema de coluna foi comprimido no terceiro compressor (8), resfriar uma segunda parte do ar (12) na primeira pressão de saída no trocador de calor e expandir pelo menos parte da segunda parte do ar em um expansor (13), a partir da primeira pressão de saída para a pressão de uma coluna (30, 31) do sistema de coluna e enviar o ar expandido para esta coluna, remover líquido (20) de uma coluna do sistema de coluna e vaporizar o líquido Por troca de calor no trocador de calor.
