Isopropyl Alcohol Production from Propane

This report presents an up-to-date, detailed cost analysis of Isopropyl Alcohol production from propane using two processes in sequence: propane dehydrogenation and direct hydration of propylene. The propane dehydrogenation process is similar to Lummus CATOFIN, while the propylene hydration is based on a conventional vapor-phase technology. In the concept under analysis, propane is dehydrogenated in fixed-bed reactors to generate propylene. Propylene, still comprising unreacted propane, is further subjected to hydration in vapor phase over a phosphoric acid catalyst. A mixture of unreacted propylene and non-reactive propane is separated from crude Isopropanol and mostly recycled to the hydration reactor inlet. The remainder is recycled to the dehydrogenation unit, where propane is converted to propylene. High-purity Isopropyl Alcohol is obtained after purification of the crude product.

Isopropanol E41A
This report presents an economic analysis of an integrated unit for producing Isopropyl Alcohol from propane in the United States. In a first unit, propane is converted to propylene via propane dehydrogenation. The propylene obtained is then converted to Isopropyl Alcohol via vapor phase hydration over a catalytic bed of phosphoric acid on silica.
