Model Number: FT-A
The computer-operated FT-A instrument is a stability diagnostic tool for quantifying the three Heithaus compatibility parameters that estimate the colloidal stability of asphalts and asphalt cross blends, aged asphalt, pyrolyzed asphalt, and heavy oil residuum. It is based on the ASTM D6703 test method for automated Heithaus titrimetry. The samples of asphalt or heavy oil or residuum are dissolved in toluene and titrated with iso-octane or n-heptane at controlled temperatures to determine the point of flocculation and calculate the Heithaus compatibility parameters. Compatibility influences important physical properties of these materials as well as the formation of coke which causes fouling in refining processes.
