Heavy fuel oil (C15H28) is a common fuel used to provide energy for commercial ship. A smaller cruise vessel fuel tank size is 495m3 a) (1 mark) Write balanced equations for the complete combustion for heavy fuel oil, stating your assumptions b) (3 marks) Calculate the amount of CO2 emitted when the cruise vessel consumes the full tank of fuel. c) (3 marks) For the same amount of energy used in part b) If you are testing a Hydrogen fueled cruise vessel, how much Hydrogen (in mass ( kg ) and Volume (L)) would you be using? Compare this with the mass and volume of Heavy fuel oil fueled cruise ship and hence the advantage and disadvantage of using Hydrogen fueled cruise ship. HHV Heavy fuel oil 41.8MJ/kg, molecular weight 208g/mol, density 980kg/m3, molecular weight of CO2 is 44g/mol. HHV H H2120MJ/kg,H2 density of 0.08239g/L Conversion 1m3=1000L
