Coal-fired power plant is operating 7000 hours per year to produce electricity with an efficiency of 40% by burring 200 tone coal per hour. The coal has a lower heating value of 27MJ/kg coal and produces 2.5 tone CO2 per ton of coal burned. 1. While capture processes may become more efficient, there is a thermodynamic limit, as with any process. Calculate the minimum energy requirement (in (1) kJ/molCO2 and (2) 313K. 2. If this minimum energy were provided in the form of electricity at a cost of 0.06S/kWh : what would be the cost per tCO2 ? Consider the mixtures as binary (i.e. there is only one component other than CO2 ). 3. Calculate the thermal and electrical capacity of the plant, in MW. 4. Calculate the plant's specific CO2 emissions in gcoz/kWh, as well as the yearly CO2 emissions (in tco22 year)
