A natural gas containing 82 mole% CH, and the balance C2H6 is used as a fuel to generate steam in an industrial plant (Figure 2). The natural gas is fed into a furnace at 25°C and burned at a rate of 10.000 mol/hr with 20% excess air. The heat transferred from the furnace is used to convert a liquid feed water at 25 °C into a saturated steam at 30 bar. During the combustion of natural gas, all the CH,...

3) A fuel gas containing 60 mole% methane and the balance ethane is burned completely with 35% excess air. The stack gas leaves the furnace at 700°C and is cooled to 250°C in a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. Taking as a basis of calculation 100 mol/s of the fuel gas fed to the furnace,...

A fuel gas containing 95 mole% methane and the balance ethane is burned completely with 25% excess air. The stack gas leaves the furnace at 900°C and is cooled to 450°C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. (a) Taking as a basis of calculation 100 mol of the fuel gas fed to the furnace, calculate the amount...

You are the design engineer for a natural gas co-generation power facility shown in the diagram below. You have been asked if the facility's exhaust gas can be fed to a greenhouse in order to grow plants without having to add a make up stream of air to cool it. This can be done if the temperature of the facility's exhaust gas is less than 130°F (54.4°C) In steady state, the Gas engine is fed a stream of natural gas...

1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l) → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...

Methane gas is burned with 30 percent excess air. This fuel enters a steady- flow combustor at 0.8 atm and 25oC and is mixed with the air. The products of combustion leave this reactor at 0.8 atm and 1600 K. Determine the equilibrium composition of the products of combustion and the amount of heat released by this combustion in kJ/kmol methane. Use data from the tables CH 25°C CO2, H3O chamber NO.
