Questions and Answers

What is the limitation of current membrane systems for oxygen production?

  • Limited to less than 400 tonnes of O2 per day (correct)
  • Limited to less than 600 tonnes of O2 per day
  • Limited to less than 800 tonnes of O2 per day
  • Limited to less than 200 tonnes of O2 per day
  • What is the equation for the minimum power requirements for oxy-fuel combustion CO2 capture?

  • $Minimum Power = \left( \frac{\ln\left(\frac{\frac{y_2}{X}}{\frac{y_{O2}}{2}}\right)}{\ln\left(\frac{p_1}{p}\right)} - \frac{\ln y_{O2} + \frac{y_2}{X}}{y_{O2}}\right) \times \left(\frac{RT}{F_{CO2}}\right)$ (correct)
  • $Minimum Power = \left( \frac{\ln\left(\frac{\frac{y_{O2}}{2}}{\frac{y_{2}}{X}}\right)}{\ln\left(\frac{p}{p_1}\right)} - \frac{\ln y_{O2} + \frac{y_{2}}{X}}{y_{O2}}\right) \times \left(\frac{RT}{F_{CO2}}\right)$
  • $Minimum Power = \left( \frac{\ln\left(\frac{\frac{y_{O2}}{X}}{\frac{y_{2}}{2}}\right)}{\ln\left(\frac{p}{p_1}\right)} - \frac{\ln y_{O2} + \frac{y_{2}}{X}}{y_{O2}}\right) \times \left(\frac{RT}{F_{CO2}}\right)$
  • $Minimum Power = \left( \frac{\ln\left(\frac{\frac{y_{2}}{X}}{\frac{y_{O2}}{2}}\right)}{\ln\left(\frac{p}{p_1}\right)} - \frac{\ln y_{O2} + \frac{y_{2}}{X}}{y_{O2}}\right) \times \left(\frac{RT}{F_{CO2}}\right)$
  • What is the value of total CO2 emissions used in the calculation of minimum power requirements?

  • 2,470 kmol/s (correct)
  • 2,370 kmol/s
  • 2,570 kmol/s
  • 2,670 kmol/s
  • What is the temperature at which the pure CO2 product is compressed to 100 bar?
