| titleOfInvention | Production process of high-purity acetaldehyde |
| abstract | The invention discloses a process for producing high-purity acetaldehyde, which comprises the following steps: gasifying ethylene glycol; dehydrating the ethylene glycol gas in a fluidized bed reactor, and arranging a heat transfer coil in the catalyst bed , to prevent the bed from flying overheating or overheating and causing deep dehydration of ethylene glycol; the gas generated by the reaction enters the gas-liquid phase separation tank after being cooled by the cooler, the gas phase material enters the water washing tower, the acetaldehyde dissolves in the water in the water washing tower, and the insoluble gas The top of the water washing tower is discharged, and the bottom liquid of the water washing tower and the liquid phase material in the phase separation tank are mixed in the first buffer tank, and then enter the acetaldehyde lightening tower through the cooler; the top of the acetaldehyde lightening tower is The gas-liquid two-phase material is discharged to further remove impurities, and the bottom liquid of the tower enters the second buffer tank, and enters the acetaldehyde weight removal tower through the feed pump, pressure reducing valve and feed cooler of the weight removal tower; in the acetaldehyde weight removal tower , acetaldehyde is separated from water and other heavy components, and acetaldehyde with a purity of 99.9wt% is obtained at the top of the weight-removing tower. |
