1. Team 7: Engineering an Alternate Route to Styrene

2. Larae Baker Adam Jones Michael Heslinga Jonathan Bush Maxine Bent

3. Outline Re-introduction Design Process Struggles Changes

4. Re-Introduction Design a styrene plant on HYSYS, a computer simulator –Capacity: 2 billion lbs/year –$0.70/lb –14% of US production New chemical process –Ethane instead of Ethylene

5. Design Process Research Base Case Detailed Equipment Design –Reactors –Separations –Other equipment Economic Optimization Finalized Design

6. Process Design

7. Struggle Separations –Not in patents –Heuristics No kinetic data –Cannot determine a rate law –Assumed conversion and selectivity

8. Changes since December Kinetics Working base case Optimization beginning Catalyst regeneration plan More detailed schedule Plant Details –50-60 acres –Texas/Louisiana
