Model Usage

Most applications in the regulatory environment have used speciation-solubility models. A few used surface complexation models. Applications of surface complexa-tion models mostly used the model and data from Dzombak and Morel (1990). Reaction path calculations are mostly limited to the titration and mixing calculations of two fluids. 

This limited application is partly due to lack of documentation, and this has prompted us to write this book. In contrast, the environmental applications of groundwater flow

These simple examples can only show the opportunity to further extend the value chain planning model usage for decision support integrated in simulation-based optimization architecture. There is an opportunity for further industry-oriented research to better understand production-price dynamics in different types of value chain networks.

The models have been applied to analyze various operations. Four examples of model usage are ... 

Complete simulation models have been formulated for cascade and Stratco sulfuric acid alkylation units and studies have confirmed the accuracy of the models. Application studies include cases in which model usage Identified profitable unit modifications, determined optimal unit capacity and optimal distillation tower operation, and compared the performance of cascade and Stratco units. "Isostripper" deisobutanizer operation was determined to be relatively unprofitable for sulfuric acid alkylation units and acid consumption on a modified cascade unit was found to be 36% below that expected for a Stratco unit. The examples presented suggest the broad applicability of the simulation models for improving alkylation unit operation. Use of the models not only pinpoints areas where significant improvements are possible, but also quantifies incentives needed to get them implemented quickly. 

In Fig. 98 the dependences In (S n) on Sf for fom PDMDAAC polymers, synthesized at different c, are shown. As it follows from the plots of Fig. 98, all four MWD curves are described by the sole curve. This is the most important result, confirming correctness of irreversible aggregation models usage for the description of pol5mierization process [222, 223]. 

An example of reference model usage for individual production is presented below. According to the data in Fig. 22.4 the requested CE criteria for the planning phase are listed below.

Hence, the stated above results have shown the modified Kemer equation application correctness for natural nanocomposites elastic response description. Really this fact by itself confirms the possibility of amorphous glassy polymers treatment as nanocomposites. Microcomposite models usage gives the clear notion about factors, influencing polymers stiffness. 

At the end, an example of MBL model usage for graphical imagining of processes occurring in SYMBAD software is presented. Algorithm presented below is described with details in article (Wojcik, J, Kosihski, W. Zieja, M. 2013).
