Question

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 completely labelled the   flow diagram of the process.

                                                                                                                               

 

ii)   Suppose   the C3H6 at 40°C and 250 kPa and Water at   0.01°C and   0.00611 bar are chosen as a reference state, find all required values of   enthalpy, Ĥi                                                                                                                                                               

                                                                                                                                    


 iii) Calculate the required   mass feed rate of the steam by using the energy balance on the system.




  



     iv) Compute the rate of heat that must   be transferred (kW) from the water to the propylene.

    The figure shows a schematic of a power plant that has two steam turbines. The water (the working fluid for the plant) leaves the high pressure turbine (HPT) as saturated vapour at 1000 [kPa]. Part of this flow is diverted to an insulated heat exchanger, which we hot airstream to create superheated steam that enters the low pressure turbine (LPT).
