| 摘要 |
The present invention relates to a process, an apparatus and a chemical agent for removing an organochemical component from a gas flowing through the froth scrubber tower at least a cross-sectional area of which is covered by a surfactant-containing froth. The surfactant-containing froth comprises at least one surfactant and a liquid and/or an organochemical solid that is soluble or dispersible in the surfactant, and a gas. The lower froth bubbles in the froth scrubber tower are destroyed by the inherent pressure of the continuously introduced froth and of the solvent taken up by the froth and by washing water and/or fresh solutions and the like introduced thereto. The liquified froth thus formed is withdrawn together with the organochemical components and subsequently separated from the surfactant-containing liquid.
