N2 - In the metallurgical industry, especially in aluminium production, the barbotage method of refining process is very popular. Nowadays many batch reactors are replaced by the continuous reactors and at the same time they become more and more popular. The paper presents short characteristics of available continuous reactors with special emphasis put on the URC - 7000 reactor. The influence of the refining gas flow rate on the process of hydrogen removal from aluminium is presented, taking into consideration the refining process of AlSi9 and AlSiCu3(Fe) alloy. The mathematical model of this process is shown, particularly the equation needed for calculation of the final hydrogen concentration as a function of the equivalent bubble diameter. The physical model (water one) of this process is also presented, mainly schemes of gas dispersion in liquid metal, taking into account the fact that the refining gas flow rate is changing from 2 to 30 dm3/min.
