Abstract
In a process for measuring the flow rate of a gas formed in an oxygen conversion process in which conversion process oxygen is introduced into an oxygen converter containing a material to be oxidized and gaseous effluent, including a gas formed in the oxygen converter, is withdrawn, the process is improved by including in the oxygen feed to the converter from 0.15 to 1% by volume argon, as a tracer, and determining the concentration of the argon in the gaseous effluent at the mouth of the converter or at a point before which the effluent gases are mixed with air or pollutant or before which the effluent gases are subjected to a combustion reaction.
