Abstract

PROCESSO E APARELHAGEM PARA A REMOçãO DA áGUA E SEPARAçãO DO AR São removidos dióxidos de carbono, óxidos nitroso e água e opcionalmente o etileno a partir de uma corrente de alimentação do ar através de uma adsorção por oscilação da temperatura utilizando um primeiro adsorvente tal como a alumina para adsorver água, um segundo adsorvente tal como zeólito 13x para adsorver dióxido de carbono, e um terceiro adsorvente tal como o zeólito x com troca de cálcio desaglutinado para adsorver o óxido nitroso e opcionalmente o etileno, antes da separação criogênica da corrente de ar purificado.
