Demonstrate, quantitatively, whether producing electricity using natural gas instead of coal has a beneficial effect in reducing the emission of CO2. [5] Use data from the European Union to quantify the impact on CO2 emissions due to the substitution of coal-fired power plants with natural gas ones in the EU. Find the data source and report it. A produced natural gas has the following composition: [5] Component C1 C2 C3 C4 C5 H2O N2 H2S CO2 Mole fraction 77% 3% 1% 0.5% 5% 2.5% 3% 2% 7% It is desired to sell natural gas at the following composition, as well as a stream containing mostly C3, C4 and C5. Component C1 C2 C3 C4 C5 H2O N2 H2S CO2 Mole fraction desired for sales gas 95% 4.5% 0.5% 0% 0% 0% 0% 0% 0% Provide a sketch of the Natural Gas Processing plant, in a block diagram form, that will allow your company to produce the desired products.
