Abstract
PROCEDIMIENTO PARA SEPARAR AIRE DE ALIMENTACION MEDIANTE CONTACTO ENTRE LIQUIDO Y VAPOR, EN CONTRA CORRIENTE EN UNA COLUMNA DE PRESION MAS ALTA Y UNA COLUMNA DE PRESION MAS BAJA, QUE ESTAN EN UNA RELACION DE INTERCAMBIO DE CALOR EN UNA ZONA ADECUADA. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE EXTRAE LIQUIDO DE LA ZONA DE RELACION DE INTERCAMBIO DE CALOR; SEGUNDA, SE VAPORIZA EL LIQUIDO EXTRAIDO MEDIANTE INTERCAMBIO INDIRECTO DE CALOR CON LA MAYOR PARTE DEL AIRE DE ALIMENTACION, PARA CONDENSAR PARCIALMENTE DICHO AIRE DE ALIMENTACION; TERCERA, SE INTRODUCE ALGO DEL VAPOR OBTENIDO EN LA COLUMNA DE PRESION MAS ALTA. DE APLICACION EN LA SEPARACION CRIOGENICA DEL AIRE PARA OBTENER OXIGENO GASEOSO A PRESION ELEVADA.
