The boiling point of a compound at P = 0.1 MPa is 150 K. The Linde liquefaction process will be used to produce saturated liquid at P = 0.1 MPa, which has a specific enthalpy of 20 kJ/kg. The Table P5-14 in the right-hand column contains some physical properties of the compound. The steady-state process works as follows.A. Find the flow rate of liquid product leaving the flash chamber.

B. Find the specific enthalpy (kJ/kg) of the vapor by-product described in step 6.

C. Find the total heat removed by the heat exchangers during step 2, in kJ/min.

D. What is the heat capacity of the compound, in kJ/kg ? K, at ideal gas conditions?

Step 1. Step 2. Step 3. Step 4. 50 kg/minute enters the process at T = 250 K and P = 0.1 MPa. The feed enters a series of compressors and heat exchangers, and it leaves the last heat exchanger at T = 200 K and P = 10 MPa. The TOTAL work added by the compres- sors is 300 kilojoules per kilogram of feed. The stream leaving step 2 is cooled to T = 175 K in a heat exchanger. The stream leaving step 3 enters a flash chamber where it expands to 0.1 MPA and some of it condenses. Step 5. The vapor from the flash chamber is used as the coolant for the heat exchanger in step 3. Step 6. The vapor stream (at P = 0.1 MPA) from step 5 is NOT recycled; it exits the process as a by-product.
