Abstract

"PROCESSO DE ADSORçãO/DESSORçãO COM OSCILAçãO DE PRESSãO". Um processo de adsorção com oscilação de pressão para a recuperação de um componente mais prontamente adsorvível, tal como nitrogênio, e uma quantidade maior de um componente menos prontamente adsorvível, tal como oxigênio, de uma mistura gasosa de alimentação, tal como ar, na qual a razão de nitrogênio para oxigênio é menor do que cerca de 3:1 e a razão de co-purga: gás de alimentação do processo é mantida menor do que cerca de 1,15:1.
