Concept explainers

Total Energy Consumption

The term energy consumption signifies the consumption of electricity. Energy consumption as electricity is a primary demand for households, factories, industries, complexes, and commercial places. According to a report, the total U.S. energy consumption for 2018 was 101 BTU (British Thermal Units). It accounted for 17% of the total energy consumption of the world. The total energy demand for the U.S. as oil equivalent was estimated to be about 6804 kg of oil equivalent.

True or False The total water content of coal can be determined by multiplying it by the total hydrogen, as all hydrogen is derived from moisture and mixed water.
What is the energy content of sub-bituminous coal?
One way to estimate the energy content of wastes is based on an empirical equation described in Rhyner et al. (1995), which utilizes an elemental analysis (also called an ultimate analysis) of the material in question:HHV (kj/kg) = 339(C) + 1,440(H) – 139(O) + 105(S)where (C), (H), and (S) are the mass percentages of carbon, hydrogen, oxygen, and sulfur in dry material (for example, cardboard is 43.73 percent carbon, so C=43.73). For the following materials, find the higher heating values (HHV) of the dry waste and the HHV of “as received” waste accounting for the moisture content. Excel may be helpful. Now, assume a city’s waste is 10% corrugated boxes, 10% junk mail, 40% mixed garbage, 10% lawn grass, 10% demolition softwood, 10% tires, and 10% polystyrene. What is the average “as-received” HHV (kJ/kg) of this waste? Finally, how much waste needs to be burned per day to power a 4 MW power plant for the city? Assume the efficiency is 50% (that is, 50% of energy created goes to…

You are treating 10 million gallons per day (MGD) of water with alum at a dosage of 50.0 mg/L. Alum is available as a hydrated salt Al2(SO4)3.16H2O. Determine:(a) The monthly alum dosage required in metric tons/month (1 metric ton = 1000 kg)(b) If you assume that each equivalent of alum added to the water consumes 1 equivalent of alkalinity, determine the alkalinity consumed by alum addition in milliequivalents/L (meq/L)(c) Given that the raw water contained 30 mg/L as CaCO3 of alkalinity, is the alkalinity sufficient? What would happen if the alkalinity is inadequate?

You place a 20 g sample of solid waste in a drying oven overnight and find the mass in the morning (after the moisture has been evaporated) to be 16.2 g. A 1 g (wet) sample is also placed in a 1L water jacket bomb calorimeter and 0.18 g of ash remains in the sample cup after combustion. The temperature in the calorimeter is raised by 2.17 ˚C. Calculate the heat value on a wet weight basis, dry weight basis, and on a moisture and ash-free basis. Convert your values to BTU/lb
