Abstract
Un procedimiento de contacto gas-líquido para la fabricación de ácido nítrico, que incluye llevar a cabo una reacción entre óxido nítrico y oxígeno, para formar tetr6xido de dinitrógeno, y una reacción entre el tetróxido de dinitrógeno así formado y el agua, para formar ácido nítrico, en que algo del oxígeno necesario es suministrado por una fuente de oxígeno comercialmente puro o de mezcla gaseosa que contiene por lo menos un 40% en volumen de oxígeno, a una o más zonas escogidas, donde tiene lugar una de las reacciones anteriormente mencionadas, o ambas, caracterizado porque el oxígeno comercialmente puro o la mezcla gaseosa que contiene por lo menos un 40% en volumen de oxígeno, está a una temperatura inferior a 0ºC cuando entra en contacto o en relación de intercambio de calor con los reaccionantes en la zona de reacción o en cada una de dichas zonas.
