Team 7: Engineering an Alternate Route to Styrene

Larae Baker Adam Jones Michael Heslinga Jonathan Bush Maxine Bent

Outline Re-introduction Design Process Struggles Changes

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

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

Process Design

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

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