Q 5. Saturated steam at 295˚C is used to heat a
counter-currently flowing stream of acetone vapour from 65˚C to
290˚C in an adiabatic heat exchanger. The inlet flow rate of the
acetone is 7500 standard litters per minute (at 1 bar), and the
steam condenses and leaves the heat exchanger as liquid water at
86˚C.
I. Calculate the rate of heat transfer from the water to the
acetone (kW).
II. Calculate the required flow rate of the entering steam in
m3/min.

Saturated steam at 300°C is used to heat a counter-current
flowing stream of methanol vapor from 65°C to 240°C in an adiabatic
(no heat exchange with surroundings) heat exchanger. The flow rate
of methanol is 400 kg/minute, and the steam condenses and leaves
the heat exchanger as liquid water at 90°C.
Calculate the required rate of heat transfer from the water to
the methanol in kW. Then, calculate the required flow rate of
entering steam in m3/min.

A heat exchanger is used to heat acetone. 10 kg/min of steam
enters at 550 C and 20.0 bar and leaves as saturated steam at 1
bar. The acetone enters at 20 C and leaves at 70 C. The heat
exchanger loses 3000 kJ/min to the surroundings. The acetone is
under a constant pressure of 1 atm.
Determine the volumetric flow rate (L/h) of acetone leaving the
heat exchanger.

Saturated steam at a gauge pressure of 0.50 bar is to be used to
heat a stream of ethane.
The ethane enters a heat exchanger at 16°C and 1.5 bar gauge
pressure at a rate of 795 m3/min and is heated at
constant pressure to 93°C.
The steam condenses and leaves the exchanger as a liquid at
20.0°C.
The specific enthalpy of ethane at the given pressure is 941 kJ/kg
at 16°C and 1073 kJ/kg at 93°C.

A heat exchanger is used to transfer heat from a steam stream to
a chlorine gas stream. 100 kg of steam at 1 bar and 250°C enters
the heat exchanger and leaves the exchanger as saturated steam at 1
bar. Chlorine gas enters the exchanger at 1 bar and 33.0°C and
leaves the exchanger at 132.0°C. Assume the heat exchanger is
adiabatic.

liquid water at 0.01°C as a reference...
