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%)
