A solid waste with 1.0 % S is combusted in a Bomb calorimeter. The temperature of the bucket water increases from 26°C to 28 °C. The water equivalent of the calorimeter is 2402 cal/°C. One gm sample is used for the test and Parr 45C10 wire is used for ignition. Out of the 10 cm wire 2.6 cm is unused. To titrate the calorimeter washing 24.2 ml of 0.0709N sodium carbonate is required. Calculate the Gross heating value of the waste. Consider the thermometers are working perfectly.
Answers & Comments
Answer:
calorimeter.
Explanation:
The initial and final temperatures
of water in bucket are 21 and 26°C respectively. The
bucket wash is titrated against N/10 Na2co3
and the
titer value is 3.5 ml. Sulphur content in the
solid
waste is 2%. Parr 45C10 NI-Cr wire is used to
ignite
the waste sample and 4 cm of the wire is
fused. The
water equivalent of the calorimeter is 2402
cal per °C
Hydrogen content of the waste is 8 %. Calculate the
HHV and LHV of the solid waste?
2776.52 Cal/gram, 2346.97 Cal/gram
3656.52 Cal/gram, 4386.97 Cal/gram
3971.7 Cal/gram, 3568,62 kcal/kg
3346.52 Cal/gram, 2346.97 Cal/gram
Answer:
Solid waste holds the greatest potential as biomass source in Libya. The rapid expansion of industry has led to increased urbanization and growing population. These factors have dramatically increased the amount of MSW (municipal solid waste) generated in Libya. However, issues related to environmentally sound MSW management—including waste decrease and clearance—have not been addressed sufficiently. This study presents an overview on solid waste that can be used as a source of bioenergy in Libya including MSW, ISW (industrial solid waste), and HSW (health care wastes) as biomass sources. The management of solid waste and valorization is based on an understanding of MSW׳s composition and physicochemical characteristics. The results show that organic matter represents 59% of waste, followed by paper–cardboard 12%, plastic 8%, miscellaneous 8%, metals 7%, glass 4%, and wood 2%. The technology of WTE (waste-to-energy) incineration, which recovers energy from discarded MSW and produces electricity and/or steam for heating, is recognized as a renewable source of energy and is playing an increasingly important role in MSW management in Libya. This paper provides an overview of this technology, including both its conversion options and its useful products (e.g., electricity, heat, greenhouse gas emissions). The WTE benefits and the major challenges in expanding WTE incineration in Libya are discussed. It also demonstrates that Libya could become an exporter of hydrogen in lieu of oil and natural gas.
