Webbalso an important foundation to further optimize the ammonia plant. Once the process is stable through MPC, complementary models can be used to further optimize operations. While the predictive models used for advanced process control are empirical dynamic models, first principles-based models can be added to the automation architecture. Webbprocess model. Optimization techniques that are used in the process industries are briefly described. For more information, see textbooks on optimization methodology (Ravindran et al., 2006; Griva et al., 2008; Edgar et al., 2001). Figure 19.1 is a detailed version of Fig. 1.7, which shows the five levels in the process control hierarchy Webbin process operation (Backx, Bosgra and Marquardt, 1998). The paper is structured as follows: Section two of the paper discusses the economic drivers and motivation for improvement of the process control and optimization technologies applied in process operations. An analysis is made of problems faced by industry. A general problem round porthole windows for sale
