摘要：
The oxygenation process comprises admitting the liquid to be treated to a pipe equipped with a gas/liquid transfer system (10) in which a neutral gas is injected for carrying out the dispersion of the inert gas in the liquid that flows within the transfer system, and gas/liquid separation. The gas/liquid transfer system comprises a system such as a venturi-type injector for injecting the neutral gas in the liquid followed by a static mixer. The step of gas/liquid separation is carried out by introducing liquid in a gas/liquid separation equipment with neutral gas. The oxygenation process comprises admitting the liquid to be treated to a pipe equipped with a gas/liquid transfer system (10) in which a neutral gas is injected for carrying out the dispersion of the inert gas in the liquid that flows within the transfer system, and gas/liquid separation. The gas/liquid transfer system comprises a system such as a venturi-type injector for injecting the neutral gas in the liquid followed by a static mixer. The step of gas/liquid separation is carried out by introducing liquid in a gas/liquid separation equipment with neutral gas that is identical or different from the neutral gas used in the first step, and directing liquid towards a packaging operation and then degassing the liquid in the packaging itself at the end of the first step. The liquid flows in a portion of pipe of length (D) between the first and the second step during a travel time (T). The injection system of neutral gas entering in the constitution of the gas/liquid transfer system comprises a porous tube laid within the pipe, and a unit for injecting gas escaping from a pore in the pipe and in the liquid that flows through the pipe. The gas/liquid transfer system consists of a first part that is a pipe made of a porous material, and a second part that is a static mixer. The liquid to be treated flows inside the pipe, and the gas is injected within the pore and diffuses in the pore inside the pipe. The stat
