Abstract:
The invention concerns an oxidising method by wet process oxidation or ozonization of a liquid contained in a reactor. The gaseous roof (20) is sucked into the liquid, the part undissolved in the liquid is recuperated in the gaseous roof. The stirring means (2) generates a liquid flux immediately proximate to the end of the conduit (3) emerging into the liquid and generates a gas/liquid dispersion in the zone (15), wherein the liquid reacts with the gas, then transports and ejects said dispersion at its periphery, such that the gas is dissolved in the liquid in the zone (16) extending from the stirring means (2) to the surface of the liquid. The method is more particularly suitable for all oxidising processes using large amounts of oxygen or ozone. It is in particular used for oxidising paper-mill liquors.
Abstract:
An apparatus (10) for dissolving a gas into a fluid which may contain at least one dissolved gas. The apparatus (10) includes a first vertically oriented tube (2) defining a first inner space (32) and a second vertically oriented tube (12). The space between the first and second tubes is referred to as the second inner space (40). The gas is introduced through an inlet (18) into the second inner space (40). The apparatus (10) includes an acceleration device (20) for accelerating the flow of fluid through the second inner space (40). The apparatus includes a helix-shaped bubble harvester (22) which removes fugitive (undissolved) bubbles from the fluid flow and returns them to the second inner space (40) to increase the probability that those bubbles will be dissolved into the fluid.
Abstract:
The present invention is an apparatus suitable for dissolving a gaseous solute in a liquid solvent. The apparatus consists of an operative chamber (1), the interior of which is attached via a transfer duct (3) to a lute chamber (2) of lesser capacity than the operative chamber (1). An outlet duct (4) extends from within the lute chamber (2) at a point above the outlet of the transfer duct (3) to the exterior of the lute chamber (2). A solvent supply inlet (5) and a solute supply (6) are connected to the operative chamber (1) and pressurised solvent and solute sources. Both inlets (5, 6) are fitted with valves (7, 8) to control the in-flow of solvent and solute.

Abstract:
The invention concerns a device enabling the gas bubbles present in a liquid composition to be dissolved. The device comprises a chamber (10) provided with an inlet orifice (11) through which the composition to be debubbled is introduced, and an outlet orifice (12) through which the debubbled composition is discharged, an ultrasonic transducer (13, 14, 15, 16, 17, 18, 19, 20), a power supply (21) for supplying the said transducer, the said power supply (21) being regulated in frequency and power at the same time. Application to photographic compositions.

Abstract:
This invention concerns an apparatus and a method for producing carbonated water capable of obtaining high concentration carbonated water effectively. Carbon dioxide gas is passed through a first carbon dioxide gas dissolver composed of a membrane module to be dissolved in water and the carbonated water passing through the first carbon dioxide gas dissolver is passed through a static mixer, which is a second carbon dioxide gas dissolver. Consequently, a high concentration carbonated water can be obtained remarkably, effectively and easily with a simpler structure than conventionally.
