04/06/2010 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.
04/06/2010 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.
