Propane gas enters a continuous adiabatic heat exchanger 240°C. Superheated steam at 300 C and 5 bar enters the exchanger flowing countercurrently to the propane and exits as a saturated liquid at the same pressure at 40 C and 250 kPa and exits at Taking flow chart. Include both mass and volumes on your inlet and outlet streams. b. Calculate the specific enthalpy values for the inlet and outlet streams. c. Use an energy balance to calculate the required mass...

An adiabatic heat exchanger is one for which no heat is exchanged with the surroundings. All of the heat lost by the hot stream is transferred to the cold stream in this adiabatic process. In a proposed process, propane gas enters a continuous adiabatic heat exchanger at 45 °C and 265 kPa and exits at 255 °C. Superheated steam at 300 °C and 7.0 bar enters the exchanger flowing countercurrently to the propane and exits as a saturated liquid at...

A stream containing ethane gas (C2He) enters the inner pipe of a double-pipe heat exchanger at 40°C and 105 kPa and exits from the pipe at 240*C and the same pressure. Superheated steam at 315 C and 5.0 bars enters the outer (annular) pipe, flowing counter-currently to the ethane, and exits as a saturated vapor at the same pressure. Neglecting the heat losses from the heat exchanger to its surroundings. Draw a diagram of the process. (5) What are the...

MATERIAL AND ENERGY BALANCE
a) Superheated steam at 300°C and 5.0 bar absolute is used to heat a counter-currently flowing stream of propylene gas in an adiabatic heat exchanger. The propylene gas enters the heat exchanger at 40°C and 250 kPa and leaves at 250°C. All of the steam condenses and emerge from the heat exchanger as a saturated liquid at the same pressure. i) Taking a basis of 100 mol/s of the feed gas, draw a...

Problem 3 Steam enters a heat exchanger at 0.1 bar with a quality of 0.95 and condensate exits at 0.1 bar and 45'C. Cooling water enters the heat exchanger in a separate stream as a liquid at 20'C and exits as a liquid at 35 C with no changes in pressure. Heat transfer from the outside of the heat exchanger and changes in the kinetic and potential energies of the flowing streams can be ignored. For steady state operation, (a)...

1. (20 points) Consider a cogeneration system operating at steady state. Superheated steam enters the first turbine stage at 6 MPa, 540 °C. Between the first and second stages, 45% of the steam is extracted at 500 kPa and diverted to a process heating load of 5 x 108 kl/h. Condensate exits the process heat exchanger at 450 kPa with specific enthalpy of 589.13 kl/kg and is mixed with liquid exiting the lower pressure pump at 450 kPa. The entire...
