10 To Hery 200K SMK Mah 300K 30 SGK MON 9.3 Consider the pharmaceutical processing facility illustrated in Figure 9-24 (El-Halwagi 1997). The feed mixture (C) is first heated to 550 K, then fed to an adiabatic reactor where an endothermic reaction takes place. The off-gases leaving the reactor (H) at 520 K are cooled to 330 K prior to being forwarded to the recovery unit. The mixture leaving the bottom of the reactor is separated into a vapor fraction and a slurry fraction. The vapor fraction (H) exits the separation unit at 380 K and is to be cooled to 300 prior to storage. The slurry fraction is washed with a hot immiscible liquid at 380 K. The wash liquid is purified and recycled to the washing unit. During purification, the temperature drops to 320 K. Therefore, the recycled liquid (C) is heated to 380 K. Two utilities are available for service, HU, and CU The cost of the heating and cooling utilities ($/10 kJ) are 3 and 5, respectively, Stream data are given in Table 9-8. A value of Armin= 10K is used. Using the pinch analysis, determine the minimum heating and cooling utilities for the process. FIGURE -24 SIMPLIFIED FLOWSHEET FOR THE PHARMACEUTICAL PROCESS EL HALWAGEN
