| titleOfInvention | A kind of method and equipment for ethylene hydroformylation gas-phase circulation production of propionaldehyde |
| abstract | The present invention relates to a method and equipment for cyclically producing propionaldehyde by ethylene hydroformylation. and the first stream of by-products; S2. the first stream is sent to the ethylene separation tower, and the second stream comprising propionaldehyde is separated; S3. the second stream is cooled to obtain propionaldehyde and a liquid phase The third stream, and the third stream is sent to the reflux tank of the ethylene separation column; S4. the third stream drawn from the reflux tank of the ethylene separation column is returned to the described third stream as a reflux through a part of the reflux pump of the ethylene separation column In the ethylene separation tower, another part is sent to the stripping tower for processing and the propionaldehyde product is obtained in the bottom of the stripping tower. The propionaldehyde product can be separated from the reaction mixture as soon as possible by adopting a shorter flow process, so that the purity of the finally obtained propionaldehyde product and the conversion rate of the raw materials are higher. |
