Glycerin Conversion to Propylene Glycol (2008 Program)

The chemistry and technology for converting crude biodiesel-derived glycerin to propylene glycol are assessed. Process technologies developed by Davy, UOP and Senergy are reviewed and the COP economics for this conversion is compared to conventional propylene oxide hydrolysis. Market information for glycerin and propylene glycol is included.
