  • Patent number: 4822926
    Abstract: A process for the recovery of a low concentration of ethylene oxide from an aqueous solution comprising salts, ethylene oxide and glycol which comprises the steps of:(1) passing the aqueous solution comprising salts and ethylene oxide through a hydrolyzing zone at elevated temperature and elevated pressure for a sufficient length of time to insure the conversion of at least the greater portion of the ethylene oxide to glycols to obtain a dilute aqueous glycol solution;(2) passing the dilute aqueous glycol solution through at least one flasher, wherein water is evaporated in the form of steam thereby producing at the bottom of the (last) flasher a solid-liquid two-phase slurry stream comprising salt-containing solids and a liquid phase comprising glycol, salt and water;(3) sending said slurry-containing stream coming out of the (last) flasher to a centrifuge and centrifuging such stream to produce a solid phase and a liquid phase; and(4) passing said centrifuged liquid phase to a flasher wherein glycols are se
