Q1 Analyze a drier that reduces the moisture content of bentonite from 11% (bone dry basis) to 4% bdb. Assume the plant processes 100 tons/day is a gas fired rotary kiln (8 ft ID x 120 ft long). The burners on high-fire contribute 12(106) Btu/hr to the system. Bentonite is a mineral mined in western USA. Refined bentonite has many industrial uses. The delivery contract for processed bentonite specifies 6% moisture (bdb) as acceptable maximum. Can the plant raise production moisture to 5%, or 5.5%. If that is physically possible, they might reduce fuel costs. Look into this idea. Your report (6 pages maximum) should include mass balances for water and bentonite. Include other energy usage reduction ideas that you think about.
Q2 Evaluate the transition from oil based world economy to an economy driven by alternative energy sources. Include economic and political analyses. Discuss new source transmission of energy (does this exist, even in the research phase?). Include an analysis of climate variation due to new source utilization. Limit 10 pages not including graphics.
