Energy to Liquify Co2 and separate it from H2O and energy to liquify CO and separate it from O2

Richard Belshaw

In this notebook, i assume constant pressure of 100 psi (industry standard) and know the temperatures of the gas coming out of the 227 MW GE 7F 05 turbine which is 2400 degrees Fahrenheit. I convert all measurements to SI, and i calculate the volumes of the gases in litres from the Van der Waals equation and the cubic polynomial in Volume and i solve for the real root of this equation to get the volumes before and after. There is a mixture of CO2 + 2H2O coming from the reaction of CH4 + 2O2 (the combustion of methane or natural gas). then i imagine using cryogenics to cool the exhaust gas down to 100 degrees celcius (the boiling point of water) and the water starts becoming liquid and can be drained off. There is the heat of vaporization to consider and it is added in. Then the CO2 remaining is cooled to -79 deg;ees celcius the boiling point of CO2, and we stop there, and the total sntropy/second and MW is calculated. The entropy/second is calculated from the mols/second being processed which is 227000kiloJoules/second/(289 kiloJoules/Mol). the 289 kJ/Mol is from the enthalpy of the methane combustion equation deltaH. I then imagine taking the CO2 changing it to CO+0.5O2 and liquifyig the CO to separate it from the O2 and then calculate the MW (energy) necessary to separate CO from O2
