Design a condenser for the following duty: 45,000 kg/h of mixed light hydrocarbon vapours to be condensed. The condenser to operate at 10 bar. The vapour will enter the condenser saturated at 60°C and the condensation will be complete at 45°C. The average molecular weight of the vapours is 52. The enthalpy of the vapour is 596.5 kJ/kg and the condensate 247.0 kJ/kg. Cooling water is available at 30°C and the temperature rise is to be limited to 10°C. Plant standards require tubes of 20 mm o.d., 16.8 mm i.d., 4.88 m (16 ft) long, of admiralty brass. The vapours are to be totally condensed and no sub-cooling is required.

Transcribed Image Text:Design a condenser for the following duty: 45,000 kg/h of mixed light hydrocarbon
vapours to be condensed. The condenser to operate at 10 bar. The vapour will enter
the condenser saturated at 60°C and the condensation will be complete at 45°C. The
average molecular weight of the vapours is 52. The enthalpy of the vapour is 596.5 kJ/kg
and the condensate 247.0 kJ/kg. Cooling water is available at 30°C and the temperature
rise is to be limited to 10°C. Plant standards require tubes of 20 mm o.d., 16.8 mm i.d.,
4.88 m (16 ft) long, of admiralty brass. The vapours are to be totally condensed and no
sub-cooling is required.
