Abstract

Un método y aparato para separar aire en el que una corriente de vapor que contiene oxígeno se remueve a partir de un generador de nitrogeno de columna sencilla y luego se divide en dos corrientes subsidiarias. Las dos corrientes subsidiarias se condensan y luego se combinan para separarse dentro de una columna de separacion para producir oxígeno líquido de pureza ultraelevada como un residuo de columna. Una de las dos corrientes subsidiarias se condensa en un equipo de transferencia calorífica y una region inferior de la columna de separacion. La otra de las dos corrientes subsidiarias se condensan dentro de un condensador superior utilizado en conexion con la columna de separacion de nitrogeno.
