PCT No. PCT/JP95/01183 Sec. 371 Date Feb. 9, 1996 Sec. 102(e) Date Feb. 9, 1996 PCT Filed Jun. 13, 1995 PCT Pub. No. WO95/34370 PCT Pub. Date Dec. 21, 1995A gas dispersion pipe into which gas is introduced through its top end portion and blown out from its bottom end portion into liquid for gas-liquid contact, and a method and a device for gas-liquid contact employing the gas dispersion pipe are disclosed. The gas dispersion pipe has its top end portion formed in a contraction pipe with its horizontal cross-sectional area decreasing downward and/or its bottom end portion formed in a nozzle structure with its horizontal cross-sectional area decreasing downward. Instead of making the gas dispersion pipe with its bottom end portion in the nozzle structure, a gas guide member with its horizontal cross-sectional area increasing downward may be disposed within the bottom end portion of the gas dispersion pipe.
