Dedini Field Testing ProgramPhase 1: Demonstration Unit (Start-up Sept/2008) 5 m³/day at Cosan plant in Sao Paulo State, Brazil • Two stage membrane module system • Vapor feed is a split stream of rectification column • Feed total pressure: 135-140 kPa • Temperature: 105 ºC • 99.5% fuel grade product.
Rack and Module Assembly • 2, 6, 12 et 24 modules per rack • Very flexible (in/out) • Compact design to minimize interconnection costs • Vertical mounting foreasy access
Energy Comparison SiftekTM vsMolecular Sieves Energy Savings 50 %
Membranes for Dehydration (MSU Replacement) • Typical feed: 90-93 wt% • Energy savings approximately 80% • Competitive CAPEX in comparison to MSU
