Abstract:
PROBLEM TO BE SOLVED: To provide a carbonated water production apparatus capable of effectively providing carbonated water of high concentration by a simple structure and technique, and a production method therefor. SOLUTION: A carbon dioxide gas is dissolved in water through a first carbon dioxide gas dissolving device (7) formed by a membrane module, and the carbonated water passed through the first carbon dioxide gas dissolving device (7) is passed through a static mixer (13), which is a second carbon dioxide gas dissolving device.

Abstract:
A method and apparatus for dissolving a gas into a fluid which may contain at least one other dissolved gas. The apparatus includes an inlet tube for receipt of the fluid from a container containing the fluid. A gas inlet is operably connected to the inlet tube for the introduction of gas into the fluid. The mixture of gas and fluid is introduced into a gas transfer device via the inlet tube. The gas transfer device is positioned below the surface of the fluid in the container so that the gas transfer device is hydrostatically pressurized in order to increase the rate and concentration at which the gas is dissolved into the fluid. The gas and fluid mixture is allowed to flow downward through the gas transfer device such that bubbles of gas are dissolved in the fluid. The fluid having the gas dissolved therein enters an outlet means positioned within the gas transfer device. The fluid having the gas dissolved therein flows upward through the outlet means and is released from the gas transfer device while the bubbles of gas which are not dissolved in the fluid are retained in the gas transfer device.
Abstract:
An apparatus for dissolving a gas into a fluid which may contain at least one dissolved gas. The apparatus includes a first vertically oriented tube defining a first inner space and a second vertically oriented tube of diameter larger than the first tube and concentrically oriented about the first tube. The space between the first and second tubes is referred to as the second inner space. The gas is introduced through an inlet into the second inner space. The apparatus includes an acceleration device for accelerating the flow of fluid through the second inner space. The apparatus includes a helix-shaped bubble harvester which removes fugitive (undissolved) bubbles from the fluid flow and returns them to the second inner space to increase the probability that those bubbles will be dissolved into the fluid.
Abstract:
Solutions of molecular oxygen in liquid hydrocarbons are prepared by bringing a liquid hydrocarbon into contact with molecular oxygen under superatmospheric pressure in a vertical absorption zone, by a process in which(a) a layer of water is maintained at the lower end of the absorption zone,(b) molecular oxygen is passed into the layer of water,(c) a liquid hydrocarbon is fed in above the layer of water,(d) the finely divided molecular oxygen rising from the layer of water is passed upward together with the liquid hydrocarbon at from 0.degree. to 50.degree. C., with thorough mixing in the absorption zone, with the proviso that no cohesive gas phase is formed, and(e) the solution of molecular oxygen in the liquid hydrocarbon is discharged in the upper part of the absorption zone.
Abstract:
An apparatus for dissolving oxygen in a body of water having a housing submerged in a body of water. A chamber in the housing containing a volume of oxygen in surface contact with the water. An apparatus for supplying oxygen to the chamber at a rate equal to the rate at which oxygen is absorbed by the water.
Abstract:
The invention concerns a process and an apparatus for continuously producing chlorine dioxide, the process comprising the steps of: feeding chlorate ions, acid and hydrogen peroxide as aqueous solutions to a reactor; reducing chlorate ions in the reactor to chlorine dioxide, thereby forming a product stream in the reactor containing chlorine dioxide; feeding motive water (5) to an eductor comprising a nozzle (26); bringing the motive water to flow through the nozzle and causing it to flow further through the eductor in an at least partially spiral or helical manner; transferring the product stream from the reactor to the eductor and mixing it with the motive water and thereby forming a diluted aqueous solution containing chlorine dioxide, and; withdrawing the diluted aqueous solution containing chlorine dioxide from the eductor.
