Abstract (en)
The entry f1 into the pressure treatment space (11) of the equipment and the exit f3 therefrom consist of ducts (13,15), each duct having an intermediate portion (13A, 15A) of high hydraulic resistance; in points (25, 25A) between said intermediate portion and the treatment space (11) a liquid is introduced under the same or slightly higher pressure than that existing in the treatment space (11); the liquid under pressure prevents the aeriform substance from exiting the treatment space (11), whereas the flow of said liquid towards the outside is limited by the intermediate portion (13A; 15A). <IMAGE>
