The Automated Flocculation Titrimeter (AFT) developed by WRI, provides a fast and accurate way to collect maltene and asphaltene stability parameters. The data is useful for predicting coking to optimizing yield, to predict or determine blend stability, or gauge the effectiveness of additives. The K47100 AFT is available through Koehler Instruments.

Useful for evaluating

  • Asphalt and Crude stability​

  • Additive performance​

  • Blending​

  • Heat exchanger fouling
