(JP10080627-A)      A gas-liquid processor comprises a static fluid mixer (30) arranged across the liquid-gas flow direction. Liquid and gas are supplied separately (32,33) to the mixer. The liquid/gas in the mixer is maintained at a pressure higher than atmospheric. Also claimed is a gas-liquid processing apparatus which includes a number of static fluid mixers arranged in parallel and positioned in a container which keeps them at least partially immersed in the liquid. Partitions divide the inside of the container between each static mixer to allow passage of liquid but not gas. Pipes connect the gas space of each section of the container to the gas introduction piping of the adjacent mixer. The pressure in the mixers is maintainer higher than atmospheric.    USE -   For adding a gas to a liquid, e.g. for substance transfer, gas absorption or dissolution, chemical reaction, or three-phase reaction of gas-liquid-solid such as in a bioreactor. It finds applications in the food industry, e.g. for adding carbon dioxide to a beverage. In the petrochemical industry it may produce an oxidation reaction, a hydrogenation reaction, or a be used to manufacture a gas diluted water. In the paper and pulp industry a liquid and sulphidised water are contacted. In environmental applications, it may be used for deep aeration, chlorine pasteurisation, exhaust gas processing, purification of industrial waste water, water supply or sewage. In the fishery industry air is mixed with water for use in a pisciculture pond.    ADVANTAGE -   There is high contacting efficiency between the gas and liquid giving a high reaction rate and mixing efficiency at low production cost.
