Problem 2.12 Power Plant Carbon Dioxide This is a unit conversion problem. Be careful of significant figures. The daily production of carbon dioxide from an 980.0 MW coal-fired power plant is estimated to be 4.1480 x 104 tons (not metric) A proposal has been made to capture and sequester the Co2 at approximately 300 K and 140 atm. At these conditions, the specific volume of CO2 is estimated to be 0.0120 m3/kg What volume of CO2 would be collected in a 3.00 year period? x 10 m the tolerance is +/-4% the tolerance is +/-4%

Explanation / Answer

CO2 produced in one year

= 4.1480 x 10^4 tons/day x 365 days/year

= 15140200 tons/yr x 1000 kg/tons

= 1.51402 x 10^10 kg/yr

Specific volume of CO2 = 0.0120 m3/kg

Volume of CO2 collected in a year

= 1.51402 x 10^10 kg/yr x 0.0120 m3/kg

= 181682400 m3/yr

Volume of CO2 collected in a 3 year period

= 3 yr x 181682400 m3/yr

= 545047200 m3

= 5.4505 x 10^8 m3
