Optimization of End Stage Operation of Ethylene Oxide Catalyst Based on Restriction Principle
The principle of limitation plays a crucial role in industrial production,emphasizing the improvement of equipment safety and the maximization of production efficiency through rational allocation and optimization under limited resource conditions.In the optimization of the final operation of ethylene oxide catalysts,it is necessary to fully consider key parameters such as catalyst activity and selectivity,optimize limiting factors such as reactant concentration,regulator dosage,and carbon dioxide concentration that affect catalyst performance,and focus on safety risks such as bed hotspots,flash temperatures,and tail burning that may occur during the final operation.this article is based on the principle of intrinsic safety design and focuses on the late stage operation of S-893 silver catalyst.Through strict parameter control and optimization of operating indicators,the catalyst's late stage operating indicators are better than expected,the reaction temperature is stable,the space-time yield is 240.7 kg EOE/(m3·h),and the selectivity has been maintained at over 87% .
