Acetone
Optimized Acetone Separations Design
Kavinetor, Inc.
Team Leader: Kavita Nyalakonda
Design Engineers: Janet Huang, Hector Perez
November 8, 1999
CENG 403
Executive Summary
Miller & Associates contracted Kavinetor, Inc. to develop and optimize a separations process simulation for a new acetone production plant. The reactor system for this acetone plant was modeled by Group C. Williams. Using their findings, Kavinetor was charged with the task of using the effluent from their reactor design and isolating acetone at a 99.9% purity. When achieving this purity, this model had to be technically sound and cost-effective.
Kavinetor utilized rigorous techniques, which involved a balance between design and economic considerations. Through the analysis of different column configurations and the resulting economic costs, an optimal design was found. This model met design specifications and economic feasibility. The optimized design was found to have a capital cost of $972,500, as compared to the preliminary design cost of $1,078,000. The utility cost of the optimized design was calculated to be $2,450,000, as compared to the preliminary design cost of $4,021,000. This resulted in an overall savings of 33% over a 20-year plant life.
Based on these results, Kavinetor recommends that this design should be implemented or undergo further analysis. Kavinetor has confidence in the design and economic analysis of this optimized simulation.
