100 kg/s of nitrogen enters a steady-state counter-current heat exchanger at T = 150 K and P = 10 MPa. The nitrogen is cooled in the heat exchanger and then enters an adiabatic flash chamber. The outlet pressure of the flash chamber is P = 0.8 MPa. The liquid leaving the flash chamber is removed as product. The vapor leaving the flash chamber is returned to the counter-current heat exchanger, in which it is heated to a temperature of 135 K. What is the flow rate of liquid product? Use Figure 2-3 for data.
A. 100 kg/s B. 60 kg/s C. 25 kg/s D. 40 kg/s E. Insufficient information to solve
