After closing the material and heat balances, we will examine the potential environmental impact (PEI) of the design. The basic information is the stream report. Table 5.16 shows material- and heat-balance data for a fresh feed of 150kmol/h phenol and 350kmol/h hydrogen, in total 14822.5kg/h. The products are cyclohexanone 9618.9 and 5017.9 cyclohexanol in the molar ratio 2 1. After simulation it is found that the amount of waste is 150.6 kg/h lights and 80 kg/h heavies. These data lead to a global yield of raw materials of 98.75%.

Since theta(5) is a probability it must be constrained to the interval [0,1] in the THETA block. Also note that changing from the nonmixture model to the mixture model required the addition of two new theta parameters. One was used to control the probability partition, and the other to specify how the two subpopulations differed. For now, note that neither can be entered into the model uniquely. They must both go into the model together, or be removed from the model together (the designated driver system), and this leads to issues regarding the hypothesis testing for the presence of a mixture (see Section 28.5). Two control stream/report/output table pairs (C2. txt/r2. TXT/T2A. TXT and C3. txt/r3. txt/t3a. txt) can be... 

Material and energy balances remain the most important results in flowsheeting. The stream report displays the way in which the raw materials are transformed in products for given performances of units. In addition, dynamic flowsheeting can mirror the time-variation of the component inventory in different locations, as well as the dynamics of energy streams. 

The basic document of a simulation is the stream report. This helps to understand the main problems in operation, but also offers a quantitative basis for communication between different members of the plant team, particularly between technical services and plant management. A remarkable feature of a PSM consists of its diagnosis value. For example, inconsistency in the material balance of some components can be explained by a malfunction of an equipment item, so that this can be traced by fault detection (Fig. 2.2 with shaded equipment) bad designed reboiler of the column 24 produces an impurity, which by propagation affects the selectivity of the reactor 20. 

Stream report (material and heat balance), including flowsheet convergence report. 

The pivotal result in flowsheeting is the stream report. Follow-up the performance of individual units is also necessary, especially the composition of the reaction mixtures and the profiles of internal variables in the separation units. 

The final input/output stream report is as follows ... 

The stream report is an image of the material and energy flows in the plant and the basic document in flowsheeting. The format of results depends on the type of process and on the level of details. This should contain state variables, as temperature, and pressure, vaporised fraction, total and partial flow rates, molar fractions, composition, on molar and mass basis, enthalpy, specific volume, etc. Normally the information can be exported to a spreadsheet. 

The inspection of the stream report is also extremely useful for debugging convergence problems, as for example by identifying faults in the specification of units or inconsistencies in the material balance. 

The stream report is the most important document and a mirror of the plant behaviour. However, this is insufficient to evaluate the quality of the simulation run. Examining the performance of each unit is compulsory. Profiles of internal variables enable to understand how the unit really works. 

Observe that 765.5 gpm is 10 percent higher than 695.9 gpm, which is equivalent to the liquid mass flow rate, 160,645 Ib/hr. When the effluent stream, ICP-BE 2, is clicked on, the stream report does not display the stream properties because the stream has been referenced to the ICP-BE stream.

Note, as another tip, one cannot see mole fractions, mass fractions, or mass flows by default in the stream results section unless they are selected in the Items to be Included in Stream Report section of the SetupIReport OptionsIStream form before mnning the problem.
