ABSTRACT:
The invention concerns a column for bringing gases or vapors and liquids into contact which uses a plurality of plates made from a highly porous, open-pore, sintered material. According to the invention, the gas and the liquid are conducted in this column countercurrent-wise; the column plates are equipped with run-off tubes which have at the lower end a gas shut-off device such that upon starting, the path for the gas is blocked by the gas shut-off device because of the liquid column contained therein. This liquid column exerts on the gas a larger pressure than corresponds to the pressure difference between the gas in the space under the associated column plate and that above. The run-off tube is of such size that it is only partly filled by the liquid column so that it can continuously adjust itself during operation. The actual reaction between the gas and the liquid takes place partially within the column plates resulting in a greater exchange between the liquid and the gas and making the column relatively insensitive to motion effects and load variations.
