Q2. Consider a process that has two process hot streams (H₁ and H₂), two process cold streams (C1 and C2), a heating utility (HU₁, which is a saturated vapor that loses its latent heat of condensation), and a cooling utility (CU₁). The problem data are given in Table 2. The cost of the heating utility is $4/106 kJ added, and the cost of the coolant is $7/106 kJ. A value of ATmin=10K is used. Employ graphical, algebraic, and optimization techniques to determine the minimum heating and cooling requirements for the process. TABLE 2. STREAM DATA FOR PROBLEM 2 Stream Flowrate x specific heat (kW/°C) Supply temperature (°C) Target temperature (°C) H₁ 10.55 249 138 H₂ 8.79 160 93 HU ? 270 270 C₁ 7.62 60 160 C₂ 6.08 116 260 CU₁ ? 38 82

2. A 1 L, 100 g (dry weight) sample is removed from a continuous crystallizer which is operated with a residence time of 1000 s. The following particle size distribution is obtained for the sample: i) Size range (um) Mass (g) 200- 300- 400 500 600-700- 800- 300 400 500 600 700 800 900 0- 100- 100 200 2.5 26.0 30.0 21.0 12.0 6.0 2.0 0.5 0.0 Microscopy based on the sieve fractions has found that a volumetric shape correction factor, ky, of 0.52, for the crystal population and the crystal density has been found to be 2000 kg/m³ Determine whether the MSMPR model describes the system. If it does so, then determine the growth and nucleation rates for this system; if it does not, suggest why reasons that may cause deviation of this CSTR type crystallizer from the MSMPR model.
