Method for oxidizing ethylene to form ethylene oxide |
| abstract |
A method for oxidizing ethylene to form ethylene oxide, comprising: providing an aqueous stream containing ethylene glycol and impurities; directing the aqueous stream to a first ion exchange treatment bed to reduce the content of the impurities; determining Whether the outlet of the first ion exchange treatment bed has a conductivity greater than about 5 μS / cm; when determining that the outlet of the first ion exchange treatment bed has a conductivity greater than about 5 μS / cm, the first The outlet of an ion exchange treatment bed is guided into a second ion exchange treatment bed; and when it is determined that the outlet of the first ion exchange treatment bed has a conductivity greater than about 60 μS / cm, the water-containing stream is Is redirected to the second ion exchange treatment bed and regenerates the first ion exchange bed. |
