Abstract
"PROCESSO DE ADSORçãO COM OSCILAçãO DE PRESSãO PARA EXTRAIR UM GáS MAIS PREFERIDO DE UMA MISTURA DO CITADO GáS MAIS PREFERIDO E UM GáS MENOS PREFERIDO". A presente invenção refere-se à recuperação de oxigênio gasoso de baixa pureza do topo de um vaso adsorvedor para dentro de um tanque receptor para ser usado como um gás de refluxo de purga. Recuperação de gás de vazio resulta em eficiência melhorada do processo. A invenção também pode empregar uma evacuação simultânea do topo do adsorvedor para remover o gás de vazio de baixa pureza enquanto a etapa de evacuação de resíduo principal estiver sendo conduzida. Estas simultâneas recuperação de gás de vazio de topo em co-corrente e evacuação de resíduo em contracorrente provenientes de ambas as extremidades do adsorvedor permite um aumento total na recuperação de produto entre 3-5% sobre a dos processos convencionais.
