Patent

CA 2675966

The invention provides a process for the production of ethylene oxide and, optionally, ethylene glycol. A base is added at one or more positions downstream of the quench section of an ethylene oxide absorber to maintain a pH in the range of 5.5 to 9.5. This mitigates corrosion in the ethylene oxide and ethylene glycol plant.

Cette invention a pour objet un procédé de production d'oxyde d'éthylène et, éventuellement, d'éthylène glycol. Une base est ajoutée dans une ou plusieurs positions en aval de la section de quench d'un absorbeur d'oxyde d'éthylène pour maintenir un pH dans la plage de 5,5 à 9,5. Ceci atténue la corrosion dans l'usine d'oxyde d'éthylène et d'éthylène glycol.
