PRODUCTION OF ISOPROPYL ALCOHOL (IPA) by Pınar Özbay Nihal Payza Zeynep Pekişen Deniz Uğurlar
Information about... • Isopropyl Alcohol • Manufacturing Processes • Process Selection • Market Research • Capacity Determination • Process Flow Diagram • Calculation Algorithms • Results & Conclusions
Isopopyl Alcohol ??? • Flammable , colorless liquid with a strong and pleasant odor • Miscible with water , ethanol , acetone and benzene • Used as a solvent and cleaning fluid Applications • Pharmaceuticals ,pesticides ,coatings ,daily-use chemicals and organic synthesis sectors • As cleaning agents used on electronic devices such as contact pins, magnetic tape deck, lenses of lazers in opticak disk drivers • Anti-freeze agent in fuel • Preservative to replace formaldehyde in strong solutions C3H7OH
IPA Manufacturing Processes • Direct Hydration • combination of water and propylene with acidic cation exchange resin catalyst • Indirect Hydration • Reaction of propylene with sulfuric acid with a heterogenous polymeric acid catalyst • Acetone • Hydrogenation of acetone Advantages of Direct Hydration • Thermally stable polymeric catalyst • High product quality improvement • Cost effective • Environmental friendly • High selectivity of IPA
Process Selection • Process for producing isopropyl alcohol, US 5,763,693 Criteria for this selection • A final product with a composition of 90% IPA and 10% water • High conversion of Direct Hydration Process • High Selectivity of IPA • Cost effectiveness • No removal units • High data availability • Less complex process • Compressor and heat exchanger addition • High pressure • No recycle of propane
Market Research • Largest producers: Shell, ExxonMobil, Sasol and Dow (72%)
Design Capacity of IPA • TUIK DATA • 5 year moving • 3 year moving • Projected Models • Consumption Projections of IPA
Design Capacity of IPA • Year difference calculation between countries Population, GDP, growth rates and consumption of countries Calculation of future population and GDP of Turkey reference year: 2005 Calculation of consumption of Turkey per capita Final design capacity of Turkey
Design Capacity of IPA • TUIK DATA • 5 year moving • 3 year moving • Projected Models • Consumption Projections of IPA The best fit Logaritmic model Design capacity of IPA in 2025 43,000 tons/year
Direct Hydration Unit (Packed Bed) • No side reaction • X = 0.75 • adiabatic rxn at 80atm • T : 406 K 428 K Component Separator(V101) • Top: Propane, propylene • Bottom: Water, propane, isopropanol Process Flow Diagram Distillation(V102) • Propylene, propane recycle to mixer • Bottom: propane 96% propylene 4% propane Mixer propane propane water propane Centrifugel Compressor & Pump • Efficiency : 0.8 Mixer 90% IPA 10% water Extraction T: 403K • Top: Isopraponal, water, propane • Bottom: Water, propane recycle to Gas-Liquid Separator(V102) T: 353 K • Top: Propane • Bottom: IPA propane propane
Calculation Algorithm Heat Exchanger Component Seperator ∆H= Hinlet- Houtlet Adiabatic Compressor *W Adiabatic Reactor
As a summary . . .düzeltçess 90% IPA as end product data availability Direct Hydration Process Less energy consumption ˜ 75% conversion of IPA cost effective Isopropyl Alcohol • Are these reasons satisfactory to design a IPA production plant by using this process? YES
