A 750 MW power plant is burning coal that has the following prop- erties (among many others): heating value = 23,500 kJ/kg, carbon con- tent = 60%, ash content 9%, sulfur content = 2.2%, and mercury content = 120 ppb. The plant has an overall thermal efficiency of 37.5%. Assume that 20% of the ash falls out in the bottom of the fur- nace and the rest (the fly ash) goes out with the gases. An ESP collects the PM, and a wet scrubber controls SO2. The required air pollution control device efficiencies are as follows: the ESP is 99.4% efficient; the wet scrubber is 92% efficient.

Derive the CO₂emission factor for the coal.

A 750 MW power plant is burning coal that has the following prop-
erties (among many others): heating value = 23,500 kJ/kg, carbon con-
tent =
60%, ash content
9%, sulfur content =
2.2%, and mercury
content = 120 ppb. The plant has an overall thermal efficiency of
37.5%. Assume that 20% of the ash falls out in the bottom of the fur-
nace and the rest (the fly ash) goes out with the gases. An ESP collects
the PM, and a wet scrubber controls SO2. The required air pollution
control device efficiencies are as follows: the ESP is 99.4% efficient;
the wet scrubber is 92% efficient.

Wastewater is treated with an activated sludge plug flow reactor, similar to one seen at the Norman Water Reclamation Facility. The BOD5 after primary treatment is 100mg/L and the effluent limit is 5 mg/L BOD5. Use 1.00 h-1 as the maximum specific growth rate constant and typical values for the other biokinetic constants. The biomass concentration in the reactor is 2,500 mg/L MLSS based on a recycle ratio of 1. Calculate the mean cell residence time, in hours for this system

Charcoal samples from Stonehenge in England wereburned in O2, and the resultant CO2 gas bubbled into asolution of Ca(OH)2 (limewater), resulting in the precipitationof CaCO3. The CaCO3 was removed by filtration anddried. A 788-mg sample of the CaCO3 had a radioactivityof 1.5x 10-2 Bq due to carbon-14. By comparison, livingorganisms undergo 15.3 disintegrations per minute pergram of carbon. Using the half-life of carbon-14, 5700 yr,calculate the age of the charcoal sample.
