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 &#x3bc;S/cm; upon determining that the outlet of the first ion exchange treatment bed has a conductivity greater than about 5 &#x3bc;S/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 &#x3bc;S/cm, redirecting the introduction of the aqueous stream to the second ion exchange treatment bed and regenerating the first ion exchange bed.

Epoxidation process

A method for assuring safety of a particular chemical process plant includes measuring, for each of a plurality of sets of proposed process conditions for a particular chemical process within the particular chemical process plant, a pressure rise rate following a deliberate contained ignition of at least one material used within the particular chemical process. From the resulting plurality of pressure rise rates that corresponds with the plurality of sets of proposed process conditions a particular pressure rise rate that allows for a safe operation of the particular chemical reaction within the particular chemical process plant may be selected. The particular chemical process may be implemented within the particular chemical process plant while using a particular set of process conditions from the plurality of sets of process conditions that corresponds with the selected pressure rise rate. As an adjunct, the particular chemical reaction may also be subsequently and additionally optimized with respect to an ancillary parameter, such as product yield or feedstock utilization.
