MODERATOR AND CATALYST PERFORMANCE OPTIMIZATION FOR EPOXIDATION OF ETHYLENE

A method for maximizing the selectivity (S) of an epoxidation catalyst in an ethylene oxide reactor system, comprising: receiving a measured reactor selectivity (Smeas), a measured reactor temperature (Tmeas), and one or more operational parameters from an ethylene oxide production system, the measured reactor selectivity (Smeas), the measured reactor temperature (Tmeas), and the one or more operational parameters comprise real-time and historical operating data points over time generated by the ethylene oxide production system, and using a processor to conduct various calculations and determination in order to output an actionable recommendation that includes a target change (Mchange) of a moderator level (M) of a chloride-containing catalyst moderator to its optimal value (Mopt). The method further includes using the processor to (f) display the actionable recommendation on a display.
