| titleOfInvention | Process for producing high purity monoethylene glycol |
| abstract | The present invention is directed to at least one separation zone, preferably 2 to 10 separation zones, particularly preferably at least in the pressure dewatering column 2 or at least the first pressure dewatering column 2 of the series of columns 2, 3, 4. A stripping zone with three to six separation zones, wherein a portion of the overhead stream of the pressure dewatering column (s) (2, 3, 4) with stripping zone is removed from the stripping zone. And, preferably, a method for distilling off high-purity monoethylene glycol from the hydrolysis product of ethylene oxide by a series of pressure dehydration, vacuum dehydration and subsequent purified distillation.n n n n High Purity Monoethylene Glycol, Pressure Dewatering, Vacuum Dewatering, Purified Distillation |
