Resumen:
This work addresses a flexibility study on a natural gas processing plant
through the integration of a process simulator to a "worst case" flexibility
strategy. The plant has a gas subcooled turboexpansion design, which is
suitable for working in dual operation mode; i.e., in either ethane production
or ethane rejection mode. The selected uncertain parameters (feed fiowrate,
condensable hydrocarbons' content, carbon dioxide content, and ambient
temperature) have great impact on process operating conditions. The use of
the worse case algorithm with the KS overestimation function for inequality
constraints has also been explored to improve computational time, and numerical
results are compared for both solution strategies. Results_ show, in
terms of both robustness and speed of computation, that this approach can be
a useful tool to complement operational analysis of large processing units,
commonly performed by simulation and "what if" studies.
