Title:

GAS-LIQUID CONTACT GAS DISPERSION PIPE, AND GAS-LIQUID CONTACT METHOD AND APPARATUS USING THE SAME

Document Type and Number:

WIPO Patent Application WO/1995/034370

Kind Code:

A1

Abstract:

The specification discloses a gas dispersion pipe in which a gas is introduced via an upper and thereinto, which is ejected via a lower end into a liquid to carry out a gas-liquid contact operation, and gas-liquid contact method and apparatus using this pipe. The gas dispersion pipe is formed so that an upper end portion thereof has a convergent pipe structure having a downwardly decreasing horizontal cross-sectional area, and/or so that a lower end portion has a nozzle structure having a downwardly decreasing horizontal cross-sectional area. This gas dispersion pipe may be provided therein with a gas guide member, the horizontal cross-sectional area of which increases downward, instead of forming the lower end portion thereof to a nozzle structure.
