Abstract: A process is proposed for distilling ethylene oxide from a mixture containing ethylene oxide in a column at an absolute pressure of 2-10 bar and a temperature of 20-180 DEG C; pure ethylene oxide is removed at the top or through a side discharge in the column and distillation takes place in a column divided up internally into a number of successive zones with structured sheet metal packs or piles of fillers, one or more quenching systems located outside the column being allocated to said zones.

Abstract: A PROCESS FOR DISTILLING ETHYLENE OXIDE OUT OF A MIXTURE COMPRISING ETHYLENE OXIDE IN A COLUMN AT AN ABSOLUTE PRESSURE OF FROM 2 X 105 TO 10 X 105 PA (2 TO 10 BAR) AND A TEMPERATURE OF 20 TO 180°C BY WITHDRAWING PURE ETHYLENE OXIDE IN THE LIQUID OR GASEOUS STATE OVERHEAD OR VIA A SIDESTREAM IN THE RECTIFYING SECTION OF THE COLUMN COMPRISES EFFECTING THE DISTILLATION IN A COLUMN HAVING ON ITS INSIDE A PLURALITY OF SUCCESSIVE ZONES OF STRUCTURED SHEET-METAL PACKING OR DUMPED BEDS OF PACKING ELEMENTS, THESE ZONES BEING ASSIGNED ONE OR MORE EXTINGUISHING SYSTEMS ON THE OUTSIDE OF THE COLUMN.
