Gas-liquid contacting method.

摘要

A gas-liquid contacting method which using a gas-liquid contacting facility comprised with a tower (6) having a reservoir (8) for a gas absorbing liquid (3) at the bottom part and a space (5) for the flow of a gas to be treated in the upper part, a header pipe (4) installed in the tower (6), a pump (11) for feeding the gas absorbing liquid (3) to the header pipe (4) from the reservoir (8) of the gas absorbing liquid, a throat pipe (2) attached to the header pipe (4), a discharge pipe (1) with cross-sectional area greater than the cross-sectional area of the throat pipe (2), and a diffuser pipe (12) that connects the throat pipe (2) and the discharge pipe (1), whereby the gas absorbing liquid boils under low pressure, by making the cross-sectional area of the throat pipe (2) to be sufficiently smaller than the cross-sectional area of the discharge pipe (1), then squirting the gas absorbing liquid into the gas to be treated from the discharge pipe (1).
