Abstract
Disclosed are methods for treating an ethylene oxide stream suitable for use in carbonylation reactions. Such treatment uses an inorganic solid to remove water from the ethylene oxide stream. Discloses are also systems to carry out the methods herein.
Claims12
A method of treating ethylene oxide, comprising:
- wetting a water-removing solid with organic solvent, or ethylene oxide, or a combination thereof;
- and
- continuously contacting the wetted water-removing solid with an ethylene oxide feed to produce a treated ethylene oxide stream,
- wherein the ethylene oxide feed comprises ethylene oxide and has an initial water content, the treated ethylene oxide stream comprises ethylene oxide and has a water content, and the water content of the treated ethylene oxide stream is lower than the initial water content, and
- wherein contacting the wetted water-removing solid with the ethylene oxide feed results in less than 10 wt % of the ethylene oxide polymerizing.
