Definitions
- the bottom product of the second vacuum dewatering column is largely anhydrous glycol; it is fed to the monoethylene glycol distillation.
- the bottom temperatures in the vacuum dewatering column (s) should as a rule not exceed 220 ° C., preferably 120 ° C. to 200 ° C., particularly preferably 160 ° C. to 180 ° C.
- the discharge of secondary components in addition to the discharge in vacuum dewatering, is improved in the pressure dewatering stage.
- the pressure dewatering column or at least the first pressure dewatering column of the cascade with at least one stripping section a separation stage, preferably 2 to 10 separation stages, particularly preferably equipped with 3 to 6 stages, part of the top stream of the dewatering column (s) being discharged with stripping section.
- FIG. 2 shows a diagram of a particularly preferred method for obtaining glycol according to the invention
- Figure 4 shows an embodiment of a method according to the invention with a pressure dewatering column with stripping section and an outlet for secondary components as a top stream and subsequent concentration in a partial condenser and a stripper.
