A chemical engineer injects limestone into the hot flue gas of a coal burning power plant to form lime, which scrubs SO2 from the gas and forms gypsum (CaSO4.2H2O). Find Kc for the following reaction CaCO3(s) <--> CaO(s) + CO2(g) if the value for Kp at 1000 K is 2.1*10^-4

A thermal power plant has received a coal sample. The plant manager is required to analyse if the auxiliary equipment and the combustion systems are ready for burning this fuel. For determining the suitability of burners and auxiliary systems, some adequate analyses are needed. The coal sample has the following ultimate analysis.

When coal is burned, the sulfur it contains is converted into sulfur dioxide. This SO2 is a serious pollutant, so it needs to be removed before it escapes from the stack of a coal fired plant. One way to remove the SO2 is to add limestone, which contains calcium carbonate, CaCO3, to the coal before it is burned. The heat of the burning coal converts the CaCO3 to calcium oxide, CaO. The calcium oxide reacts with the sulfur dioxide in...

A power plant engineer states that his/her power plant absorbs 100 MW heat from burning coal at 1000 K, produces 60 MW work and rejects 40 MW heat in a condenser at 300K. The pressure of steam in the boiler and condenser is 5 MPa and 100 kPa, respectively. Please calculate the total entropy generated in this case.

Sulfur dioxide is a toxic gas that is admitted into the atmosphere from volcanic irruption's as well as from human activities such as coal burning. Sulfur dioxide canreact with water in the atmosphere to form sulfuric acid, a key component in acid rain. To prevent acid rain, coal plants are required by the US EPA to clean the sulfur dioxide from there emmissions using lime (CaO) according to the following reaction: CaO(s)+SO2(g)-->CaSO3(s) If a power plant emmits 10,000 L of...

A 440-MW coal-fired power plant is burning coal that contains 185 ppb of Mercury. The coal firing rate is 300,000 lb/hr, and the flue gas flow rate is 1.0 million SCFM. The mercury standard that must be met is 0.015 lb/GWh of gross energy output. Calculate the overall mercury capture percentage that is required to meet this standard. If the wet scrubber can remove 40% of the mercury that comes into it, what removal efficiency is needed for the activated...

a) At standard conditions, the exhaust gas from a well-controlled coal-burning power plant contains 5 ppmv sulfur dioxide (SO2). At STP (0° C and 1 atm), determine the concentration of SO2 emitted on a µg/m3 basis. b) What is the equilibrium concentration of a gas in water if its partial pressure is 0.1 atm and its Henry’s law constant is 0.1 mole/(liter.atm)?

1) A coal fired power plant produces 1.00x10^14 J per day by burning coal. If the efficiency is 40.0%, how much work does the turbines do? 2) How much energy is lost to the environment (as heat)? 3) If 1 kg of coal can produce 2.5x10^6 J, and 1 kg of coal produces 3.67 kg of CO2, how much CO2 is produced in a year from this plant? 4) If there are 1000 such power plants worldwide, how long will...
