| titleOfInvention | The method that in AKD production, crude product triethylamine recycles |
| abstract | The present invention relates to a kind of method that during AKD produces, crude product triethylamine recycles, comprise the steps: that a, crude product triethylamine decanter carry out crude separation；Entering vaporizer top after the preheating of b, the most preheated device, heavy constituent enters revaporizer, continues the triethylamine of evaporation residual at revaporizer, and heavy constituent is discharged from the bottom of tower；C, light component continuously enter rectifying column after evaporation, remove the micro-moisture in triethylamine according to azeotropic distillation principle；D, in crude product triethylamine evaporation process with the solid particle of trace, the filter being arranged at the bottom of tower remove.Crude product triethylamine in AKD production process is processed Posterior circle and is used in the middle of the production of AKD by the present invention, there is no the exhaust emission of waste water and waste residue, use gas-phase feed, reduce the consumption of steam, and the response rate of triethylamine is high, reduce the production cost of AKD product, bring more significantly economic benefit. |
