The role and performance of physical, dynamic models in the hydrocarbon processing industries

Physical, first principles, dynamic models play an important role today in improving performance in the hydrocarbon industry. Recent technology advances have made it possible to use the same core dynamic model for multiple functions including both online and off-line control, engineering and training. Multiple use of the same dynamic model spreads initial cost over several applications and results in lower long-term maintenance costs. The performance of online systems over widely varying operating conditions has been demonstrated accompanied by high service factors and low maintenance. This paper focuses on the online application of physical dynamic models and the use of the same core technology as applied off-line
