  Terephthalic acid (TPA) is synthesized from -xylene (PX) in the process C8H10 +302 – C8H6O4 +2H2O shown below. A fresh feed of pure liquid PX combines with a recycle stream containing PX and a solution (S) of a catalyst (a cobalt salt) in a solvent (methanol). The combined stream, which contains S and PX in a 3:1 mass ratio, is fed to a reactor in which 90% of the PX is converted to TPA. A stream of air at 25...

  A vapor compression refrigeration cycle utilizes R-134a as the working fluid. The refrigerant flow rate is 50 g/s. Vapor at 150 kPa and -10 °C enters the compressor and leaves at 1.2 MPa and 75 °C. The power input to the non-adiabatic compressor is measured and found to be 2.4 kW. The refrigerant enters the expansion valve at 1.15 MPa and 40 °C and leaves the evaporator at 160 kPa and -15 °C. Determine the entropy generation in the compression...
