Second Case Study

Scenario 4 Formulation for fixed water quantity with reusable water storage 

The operating costs entail raw material costs and effluent treatment costs. Only scenarios 1 and 3, i.e. fixed outlet concentration with and without reusable water storage, are considered. The additional information provided for the case study pertains to the mass ratios between raw material streams and freshwater. In process 1, 1 kg of water (aqueous phase) is required to wash 3 kg of raw material stream (organic phase) to the desired specification. In process 2, 1 kg of water is required for every 2 kg of raw material stream. These requirements are dictated by mass transfer. 

Scenario I Fixed outlet concentration without reusable water storage 

Since the capacity of operating units and mass ratios between freshwater and raw 

These constraints ensure that the overall input into each of the units does not exceed the capacity of the units, i.e. 200 t.

In the second case study, variation tree analysis and the events and causal factors chart/root cause analysis method are applied to an incident in a resin plant. This case study illustrates the application of retrospective analysis methods to identify the imderlying causes of an incident and to prescribe remedial actions. This approach is one of the recommended strategies in the overall error management framework described in Chapter 8. 

The second case study (Section 21.3), focusing on tlie healtli impact of the release of toxic vapors during transportation of a hazardous chemical, illustrated tlie derivation of a risk curve showing tlie relation between number of people affected and average aimual frequency of exposure to a potential letlial concentration of toxic vapors. 

The second case study. This involves all silica micro- and mesoporous SBA-15 materials. SBA-15 materials are prepared using triblock copolymers as structure-directing templates. Typically, calcined SBA-15 displays pore sizes between 50 and 90 A and specific surface areas of 600-700 m g with pore volumes of 0.8-1.2cm g h Application of the Fenton concept to mesoporous materials looks simpler since mass transfer would be much less limited. However, it is not straightforward because hydrolysis can take place in the aqueous phase. 

Finally, the coupling of SLCA, further evaluation criteria and multi-objective optimisation are demonstrated with the help of a second case study dealing with the improvement of synthesis strategies for ionic liquids (see Section 7.5).

The second case study is that of Example 10.2 given in Figure 10.1. As before, the measurement errors of sensors 2 and 5, and sensors 6 and 11 are to be correlated. 

The second case study corresponds to an existing pyrolysis reactor also located at the Orica Botany Site in Sydney, Australia. This example demonstrates the usefulness of simplified mass and energy balances in data reconciliation. Both linear and nonlinear reconciliation techniques are used, as well as the strategy for joint parameter estimation and data reconciliation. Furthermore, the use of sequential processing of information for identifying inconsistencies in the operation of the furnace is discussed.

First, the classical three states of matter and the transition from one state to another will be critically discussed. Second, case studies will be presented for a subsequent comparison with similar phenomena in the Leld of powdertechnology. 

In the following, the concept of micro modular process engineering is introduced together with the backbone interface developed in order to realize this modular approach. The integration of sensors and an electronic bus system is also described, and the physical characterization of the backbone is discussed within a case study of the enantioselective synthesis of organoboranes. Within the second case study, the sulfonation of toluene with gaseous sulfur tri oxide, the backbone system together with the micro structured devices used is finally assessed based on its application to chemical synthesis. 

The second case study is of two-way diode array detector (DAD) HPLC data of a small embedded peak, that of 3-hydroxypyridine, buried within a major peak (2-hydroxypyr-idine). The concentration of the embedded peak varies between 1 and 5% of the 2-hydroxypyridine, and a series of 14 chromatograms (including replicates) are recorded whose concentrations are given in Table 3.
