| titleOfInvention | Neopentyl glycol raw materials for production recovery system |
| abstract | The utility model relates to a neopentyl glycol production field of making specifically discloses a neopentyl glycol raw materials for production recovery system. The method mainly solves the technical problems that in the prior art, the gas phase condensation effect of formaldehyde and trimethylamine separated from the top of a distillation tower is not ideal, so that valuable components which are as much as possible cannot be recycled, the raw material waste is serious, and the emission of tail gas is increased. The utility model discloses, include: the distillation tower is an atmospheric distillation tower; the condenser is arranged at the top of the distillation tower; the reflux tank is arranged below the condenser; a liquefied gas compression system; and the gas phase channel is used for respectively communicating the condenser with the liquefied gas compression system and communicating the reflux tank with the liquefied gas compression system, compressing and liquefying components which cannot be condensed in the condenser by a physical compression method and sending the components back to the reaction system, so that the consumption of formaldehyde and trimethylamine is reduced, the utilization rate of raw materials is improved, the load of a tail gas treatment device is reduced, and the emission of carbon dioxide and nitrogen oxides is reduced. |
