    Abstract: A method for the oxidation of ethylene to form ethylene oxide is provided that includes passing an aqueous stream through a guard bed and one or more ion exchange treatment beds. The guard bed and the aqueous stream contain from about 0.2 to 20 wt % ethylene glycol. The guard bed contains a cross-linked polystyrene resin, partially functionalized with quaternary ammonium functional groups and the resin has a surface area of greater than 400 m2/g.

    Abstract: A method for the oxidation of ethylene to form ethylene oxide which comprises: providing an aqueous stream containing ethylene glycol and impurities; introducing the aqueous stream in a first ion exchange treatment bed to reduce the content of these impurities; determining whether an outlet of the first ion exchange treatment bed has a conductivity greater than about 5 μS/cm; upon determining that the outlet of the first ion exchange treatment bed has a conductivity greater than about 5 μS/cm, introducing the outlet of the first ion exchange treatment bed into a second ion exchange treatment bed; and upon determining that the outlet of the first ion exchange treatment bed has a conductivity greater than about 60 μS/cm, redirecting the introduction of the aqueous stream to the second ion exchange treatment bed and regenerating the first ion exchange bed.
