Abstract

Un dispositivo para fraccionar gas, más particularmente oxígeno líquido a partir de aire, por medio de una columna de fraccionamiento de gas que está conectada a un refrigerador de gas frío, conduciendo la salida para la mezcla de gases fríos producida en la columna a un permutador térmico que tiene una conexión para gas comprimido a fraccionar, junto con una salida para gas enfriado por medio de dicho vapor frío, conduciendo la salida últimamente mencionada a la columna de fraccionamiento de gas, caracterizado porque el conducto de alimentación para el gas a fraccionar, antes de que este gas entre en el permutador térmico, está provisto de un ramal que incluye un miembro de regulación, por ejemplo una válvula, y que conduce a una zona donde las impurezas, tales como agua y ácido carbónico, pueden separarse del gas que pasa a través de dicho conducto por medio del refrigerador de gas frío, antes de que este gas será conducido a la columna de fraccionamiento de gas después de su condensación total o parcial.
