  10. General Plant Layout • Plant is to be adjacent to paper mill to obtain a cheaper source of black liquor Plant Dimensions 250 x 185(285) x 40 Team Bravo: Presentation 4

  11. Calculations: Lignin Reactor • Reactor Size • Diameter = 7 ft • Height = 20 ft • Volume = 5700 gallons Heat Duty = 830,000 BTU/hr Total Cost of Unit = $1,340,000 Team Bravo: Presentation 4

  12. Calculations: Distillation Column • Column Size • Number of Trays = 9 • Diameter = 1.5 ft • Height = 30 ft • Volume = 400 gallons Reboiler Heat Duty = 420,000 BTU/hr Condenser Heat Duty = -47,000 BTU/hr Total Cost of Unit = $410,000 Team Bravo: Presentation 4

  13. General Economic Evaluation • Capital Costs • $22,500,000 • Utilities • $642,000/year • Raw Materials • $14,900,000/year • Labor and Maintenance • $1,900,000/year • Other Costs • $3,440,000/year • Total Operating Costs • $20,800,000/year • Total Product Sales • $30,400,000/year • Profit per Year • $9,550,000/year • Payback Period (x) • 2 > x > 3 Years Team Bravo: Presentation 4

  14. Summary • Block flow and process flow diagrams are nearly finalized. • Basic control schemes have been added to the process flow diagrams. • Our payback period is between 2 to 3 years. • We have drafted the general arrangement of our DMSO plant. • Further details and higher-detail drawings are available on our Wiki. • http://che397-teambravo.wikispaces.com/ Team Bravo: Presentation 4

  15. Future Goals • Pinch analysis and heat integration. • Utility optimization. • Waste processing. • Pumps and compressor adjustments. • More detailed control scheme. • P&ID • Applicable standards, environmental regulations, OSHA requirements. Team Bravo: Presentation 4
