In a first phase, the micro-biological conversion of ethanol into acetic acid is performed in the presence of air. After consumption of the oxygen in the air, in a second phase, the addition of oxygen, controlled by the demand of the system, is provided by injection of pure oxygen, the aeration gas being recycled, and the gas mixture expelled as soon as the carbon dioxide content reaches the threshold of 7%. After closing of the recycling circuit, the superoxygenated atmosphere is reconstituted with pure oxygen. |
