| titleOfInvention | A kind of device and method for producing styrene by dehydration of phenethyl alcohol |
| abstract | The invention belongs to the field of styrene and discloses a device and method for preparing styrene by dehydration of phenylethanol. The device includes: a dehydration tower, a dehydration tower condenser, a dehydration tower reflux tank, a dehydration tower kettle circulating pump, and a dehydration tower reboiler; wherein the catalyst feed line is connected to the dehydration tower kettle, and the crude phenethyl alcohol feed line is connected to the dehydration tower. The inlet of the kettle and/or the reboiler of the dehydration tower; the top of the dehydration tower is sequentially connected to the dehydration tower condenser and the dehydration tower reflux tank; the dehydration tower reflux tank is connected to the dehydration tower; the bottom of the dehydration tower is sequentially connected to the dehydration tower kettle circulating pump and the dehydration tower reboiler The outlet of the reboiler of the dehydration tower is connected to the dehydration tower; wherein, the reboiler of the dehydration tower is a shell-and-tube heat exchanger. The invention utilizes the reboiler of the dehydration tower as the reactor, so that the phenethyl alcohol and the catalyst are mixed evenly, and react immediately after entering the reboiler of the dehydration tower, thereby reducing the residence time of the phenethyl alcohol, thereby reducing the volume of the reactor and reducing equipment investment. |
