Toluene equipment parameters

For an equimolar feed stream, SI, at 1,000 Ibmol/hr and 100°F, the flow rate of a toluene stream, S2, at SOT is adjusted to achieve a desired temperature of the mixer effluent (e.g., 85"F), as shown in Figure 4.8a. Convergence units for feedback control (design specifications) are shown on simulation flowsheets as dotted circles connected to streams and simulation units by dotted arcs. The arcs represent the information flow of stream variables to the control unit and information flow of adjusted equipment parameters to simulation units. Note that the control units of most simulators can adjust the flow rates of the streams. After the calculations by the MIXER subroutine are completed, the control subroutine samples the effluent temperature. It adjusts the flow rate of stream S2 when the specified temperature is not achieved and transfers to the MIXER subroutine to repeat the mixing calculations. This cycle is repeated until the convergence criteria are satisfied or the maximum number of iterations is exceeded. 

Refer to the information given in Chapter 1 for the toluene hydrodeallq lation process, namely. Figure 1.7 and Tables 1.5 and L7. Using the information provided in the tables in this chapter, estimate the size of the equipment and other operating parameters for the following units a. V-102...
