Operability for processes with recycles: interaction between design and operation with application to the tennessee Eastman challenge process

摘要

In this work, a complex process with recycles, Tennessee Eastman Challenge Process, is studied to explore the operability for plants with recycles. A simplified process model is constructed to provide physical insight into the Eastman plantwide process. The results show that the composition distribution in the reactor (or the recycle flow rate) plays an important role in determining the optimal operating condition, i.e., achieving maximum one-pass conversion.
