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...

A stream of 70kg/hr superheated steam is used to heat 15kmol/hr
nitrogen gas via a heat exchanger. The superheated steam at
3500C and 1 bar enters the heat exchanger and exits as
saturated water liquid at the same pressure.The nitrogen gas is
heated from 25oC to 300oC at constant
pressure of 1atm.The heat exchanger is set up for countercurrent
flow.
