Process and apparatus for treating a gas stream with scrubbing liquid

摘要

In a process for treating a gas stream with scrubbing liquid in which the gas stream successively flows through at least one scrubbing stage charged with scrubbing liquid, a gas-liquid separation stage and a scrubbing liquid-charged further scrubbing stage and the scrubbing liquid in both scrubbing stages falls down as essentially uniformly distributed rain and in the separation stage the scrubbing liquid of the scrubbing stage arranged above the separation stage is essentially separated from the gas stream, in particular process for removing sulphur dioxide using aqueous alkali suspension in the two scrubbing stages, to achieve a more uniform flow distribution, it is provided that in the separation stage, the rain falling into it is combined into a plurality of part-streams and led off, between which part-streams the gas stream can enter in a plurality of part-streams into the scrubbing stage through which the flow is to pass downstream of the separation stage. <IMAGE>
