Abstract: A process for reducing unreacted monomers and condensable and non-condensable hydrocarbon fractions in an APAO which includes introducing molten APAO into heated and insulated jacketed pipe while injecting a stripping agent based on the total weight of the contents of the jacketed pipe; maintaining the stripping agent with the molten APAO stream from ten seconds to ten minutes, forming a flowable heated mixture at 250 to 450 degrees Fahrenheit in the heated and jacketed pipe forming a flowing heated mixture; and passing the flowing heated mixture through a thin film evaporator assembly, while maintaining the temperature of the flowing heated mixture, stripping the organoleptic species and acids and volatile organic components from the flowing heated mixture and removing and recovering a condensable fuel fraction and a non-condensable hydrocarbon gas with energy, while simultaneously forming an odor-reduced, cleaned molten APAO-based HMA.
