Technical Data: Quality Control of Pyrolysis Gasoline Using Near-Infrared Analysis.
With a near-infrared analyzer, the diene value (anhydrous maleic acid value) of pyrolysis gasoline (pygas) can be measured in under one minute!
Near-Infrared Analyzer Technical Data 16 Petroleum Gasoline Fuel Pyrolysis Gasoline Pyrolysis gasoline (Pygas) is a byproduct of ethylene production and is unsuitable as motor fuel due to the presence of unwanted conjugated diolefins. To eliminate this drawback, it is necessary to reduce the olefin content to below 2 mg/g using a Selective Hydrogenation Unit (SHU). The diene value (or Maleic Anhydride Value (MAV)) is typically determined by wet chemical analysis through the Diels-Alder reaction (UOP326-17). This wet chemical analysis method requires trained analysts to perform it over several hours. Near-Infrared Spectroscopy (NIRS) contrasts with this chemical analysis method and can be applied as a cost-effective, rapid analytical technique for determining the diene value in pyrolysis gasoline.
