Re-Rating Ethylene Plant Equipment for Optimum Results

AIChE Spring Meeting and Global Congress on Process Safety
April 2, 2012 - 12:00am

Rerating of turbomachinery equipment installed in ethylene plants is a well established method of improving plant operation, whether it is capacity changes, feedstock flexibility, power reduction or combination of all three.
By utilizing modern compressor and steam turbine component technology, rerating already installed equipment can achieve the desired plant operating objectives.
Through careful planning beginning with review of the process parameters to execution of the turnaround, rerating of existing euipment can provide optimal process performance and efficiency improvements accomplished in a normal maintenance shutdown.
Recent case studies will provide examples of Elliott's experience in achieving the desired process operation and improved turbomachinery performance using modern component technology while meeting normal shutdown schedules.
