Description:

A real-time, closed-loop optimization of the PenexTM process for light naphtha isomerization has been implemented at RVI’s Ingolstadt refinery using state-of-the-art technology. In this project the traditional optimization cycle that relies on steady-state detection has been further enhanced to allow for plant optimization when the process is not at steady-state. Experience at the RVI refinery indicates that the nonsteady-state optimization approach accounts for approximately one-quarter of the total project benefit. This approach adds value to processes characterized by large time constants relative to the frequency of disturbances. UOP has extended this approach to handle a multiunit naphtha complex that consists of a naphtha hydrotreater, a Penex isomerization unit and a CCR PlatformingTM unit. This paper also discusses new technology to characterize the detailed component breakdown of the naphtha splitter feed, new methodologies for multi unit-data reconciliation, and new technology for the implementation of rigorous kinetic models into open form environments.
