Refinery wide simulation (original) (raw)

Hydrocarbon engineering, 2004

Abstract

Process simulation has been widely used in refineries for more than 30 years. Steady state and dynamic simulations are established tools for the design of new process units and optimisation (off and online) of existing facilities. While mathematical models of separation systems and other unit operations are available in most commercial process simulators, refinery reactors are very specialised models and, in most cases, are simulated as standalone units. As a consequence, the interactions between different processing units are not fully explored and the true operating window is never captured. Many refiners have recognised the potential benefits of extending rigorous modelling to refinery wide simulations that model all of the process units as an integrated system. This approach would provide a powerful tool to help optimise refinery operations, and would be an important element in sustaining a competitive advantage in light of new regulations, growing competition and decreasing mar...
