- A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 9.0 mole% methane in air flowing at a rate of 7:00 x 102 kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. Calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (Note: Air may be taken to consist of 21 mole% O2 and 79% N2 and to have an average molecular weight of 29.0.)arrow_forwardA gaseous fuel containing methane and ethane is burned with excess air. The fuel enters the furnace at 25°C and 1 atm, and the air enters at 200°C and 1 atm. The stack gas leaves the furnace at 800°C and 1 atm and contains 5.32 mole% CO2, 1.60% CO, 7.32% O₂, 12.24% H₂O, and the balance ₂. 1. Calculate the molar percentages of methane and ethane in the fuel gas and the percentage excess air fed to the reactor. 2. Calculate the heat (kJ) transferred from the reactor per cubic meter of fuel gas fed. 3. A proposal has been made to lower the feed rate of air to the furnace. State advantages and a drawback of doing so.arrow_forwardThe boiler in an apartment building uses propane (C3H8) to heat water that circulates throughout the building as steam. 1.00 m'/s of propane gas at 25°C and 1 atm is combusted with 10% excess air at 25°C and 1 atm. After all of the propane is combusted, the product gas contains a 10.0:1 molar ratio of CO2 to CO and leaves the boiler at 25°C. Heat from the boiler is transferred to a pure water stream at 50°C and 1.0 bar, which is converted into saturated steam at 20 bar, with no heat lost to the surroundings in the process.

- L-lysine is produced by Corynebacterium glutamicum in a bioreactor using glucose as the carbon source and ammonia as the nitrogen source. All streams of this process are aqueous. In the inflow, 8 grams of glucose per 100 grams of flow fluid flowing at a rate of 500 kg / hour is included. The glucose flow rate in the exit steam is 1 kg / hour. The reaction takes place at 25 °c.What is the mole percentage of glucose that was consumed during cell growth inside the bioreactor? -Does the growth of Corynebacterium glutamicum cells inside this bioreactor release or absorbheat? Should heat be supplied to the bioreactor, or removed from, to maintain the operation temperature? I want the solution of both options.arrow_forwardThe liquefied petrolieum gas(LPG) is composed of 80% C;Hg and 20% C4H10 in mass basis. (1). Determine the molar fraction of C3H8 and C4H10 in LPG.

- A hydrocarbon stream composed of 40 mol% n-butane and 60 mol% n-octane is fed at 100 kmol/h to a flash vessel operating at 5 bar and 145°C. The liquid outlet stream of the flash vessel is then sent to a distillation column with a partial condenser to further separate the components. 90% of the butane in the feed to the column is recovered in the overhead vapor product (distillate), along with small amounts of octane. The bottoms product contains octane which accounts for 75% of the octane in the fresh hydrocarbon feed (to the flash vessel). The condenser and reboiler operating temperatures are 136.7°C and 165.7°C, respectively. Determine the compositions of the liquid outlet stream of the condenser and the vapor outlet stream of the reboiler.arrow_forward3. A gas contained within a closed piston-cylinder assembly undergoes three processes in series: Process 1-2: Constant volume from P₁ = 1 bar, V₁ = 4 m³ to state 2, where P₂ = 2 bar; Process 2-3: Compression to V3 = 2 m³, during which the pressure-volume relationship is PV = constant; Process 3-4: Constant pressure to state 4, where V4 = 1 m³; (a) Sketch the processes in series on P-V coordinates.
