===== Let's consider each cost component in detail: ===== ====== Using conventional energy sources, the energy requirement to produce 1 ton of silicon is approximately 12 MWh. For 64 tons (the daily processing capacity aided by CSP), the total energy requirement is: ====== Total Energy Required=64 tons×12 MWh/ton=768 MWh/day\text{Total Energy Required} = 64 \, \text{tons} \times 12 \, \text{MWh/ton} = 768 \, \text{MWh/day}Total Energy Required=64tons×12MWh/ton=768MWh/day With an electricity cost of $0.05 per kWh: Energy Cost=768,000 kWh/day×$0.05/kWh=$38,400 per day\text{Energy Cost} = 768,000 \, \text{kWh/day} \times \$0.05/\text{kWh} = \$38,400 \, \text{per day}Energy Cost=768,000kWh/day×$0.05/kWh=$38,400per day This is the amount saved by using CSP, as calculated earlier. ====== Assuming the following prices: ====== * Silica (sand): $50 per ton. * Carbon (reducing agent): $300 per ton. * Other additives and materials: $100 per ton of silicon produced. For producing 64 tons of silicon per day: Cost of Silica=64 tons/day×$50/ton=$3,200 per day\text{Cost of Silica} = 64 \, \text{tons/day} \times \$50/\text{ton} = \$3,200 \, \text{per day}Cost of Silica=64tons/day×$50/ton=$3,200per day Cost of Carbon=64 tons/day×$300/ton=$19,200 per day\text{Cost of Carbon} = 64 \, \text{tons/day} \times \$300/\text{ton} = \$19,200 \, \text{per day}Cost of Carbon=64tons/day×$300/ton=$19,200per day Cost of Other Materials=64 tons/day×$100/ton=$6,400 per day\text{Cost of Other Materials} = 64 \, \text{tons/day} \times \$100/\text{ton} = \$6,400 \, \text{per day}Cost of Other Materials=64tons/day×$100/ton=$6,400per day Total raw material cost per day: Total Raw Material Cost=$3,200+$19,200+$6,400=$28,800 per day\text{Total Raw Material Cost} = \$3,200 + \$19,200 + \$6,400 = \$28,800 \, \text{per day}Total Raw Material Cost=$3,200+$19,200+$6,400=$28,800per day ====== Assume the labor cost is $10,000 per day for a medium-sized silicon production facility. ====== ====== Assume these costs are $15,000 per day, covering equipment maintenance, utilities, administrative expenses, etc. ======
