n-butane burns with 15% excess air, both streams enter at 25 ° C. The gas burns completely producing 90 mol of CO2 / 10mol of CO. The combustion gas comes out at 400ºC and 1 atm. Taking as a basis of calculation 1000 moles / h of the gas that feeds the oven: 1. Draw the process diagram 2. Calculate the air feed rate and the composition of the flue gases. 3. Fill the enthalpy table in / out of...

3. (20) Fire Heater Specification After the reactor feed leaves the heat exchanger, it enters a fire heater. In this unit the stream is further heated from 215°C to 350°C, which requires 4649 kJ/h of heat to be added. To accomplish this, the heat from the combustion of methane gas is used: CH4(2) +2 02(g) → CO2() + 2 H20(2) $ = 10.0 molh The design of this fire heater indicates that the temperature of the flue gas will not...

Natural Gas burns according to the chemical reaction CHs:20 COHeat where Heat 15MWh/ton of CH4 burned. Atomic weights are 12 for C,I for H, and 16 for O. Consider a Combined Cycle Natural Gas Turbine (CCGT) electricity generating unit with capacity 1000MW that converts heat to Electricity at an efficiency of 60%. Consider also an algae-based photosynthesis process that converts COn from the stack of the CCGT to CHnat the rate of 10 tons of CHe per acre per year....

Natural gas burns in air to form carbon dioxide and water, releasing heat. CH4(g)+2O2(g)→CO2(g)+2H2O(g) ΔHorxn = -802.3 kJ You may want to reference (Page 269) Section 6.6 while completing this problem.What minimum mass of CH4 is required to heat 85.0 g of water by 23.0 ∘C? (Assume 100% heating efficiency.) (For water,Cs= 4.18 J/g∘C).
