Q3. A turboexpander (adiabatic) used for the power recovery in a fluid catalytic cracking unit is shown in Figure 2. The vapor leaves the turbine as saturated vapor. The mass flow rate of the vapor throughout of the process is 100kg/s and surrounding temperature is 25C. Pressure and temperature values of the streams are given in the Figure 2. Make a thermodynamic analysis of the process and calculate the thermodynamic efficiency (0)
