<p>. In order to recover the costly gas argon from the exhausts of an AOD converter as used in refining stainless steels, a method is disclosed which provides at least one gas blanket around the exhaust gas stream. The blanketing gas is preferably carbon dioxide, but also argon itself and steam, or their mixtures, can be used, it being required that the blanketing gas be easily separable from argon in order to recover the latter and to recycle it. Scrubbing and purification stages can also be additionally provided.</p> |
