Method for removing acrolein from the process gas of a heterogeneously catalysed oxidation of propene |
| abstract |
The invention relates to a process for separating acrolein from the process gas of a heterogeneously catalysed oxidation of propene by means of atmospheric oxygen, wherein high boilers (including acrylic acid) are firstly separated off from the process gas by means of quenching and technical-grade acrolein having small proportions of low boilers is then obtained by means of absorption and subsequent distillation. Small amounts of a solvent by means of which, in particular, oligomers formed are separated off and the tendency for foam to be formed in the apparatuses or columns is reduced is added in the columns and heat exchangers in the work-up process. The solvent is, according to the invention, separated off and recycled in the form of an organic phase in-situ within the existing process. |
