Automated Heithaus flocculation titrimeter system and trainers

The Automated Heithaus flocculation titrimeter system and trainers is a stability diagnostic tool utilized to quantify the three Heithaus compatibility parameters which estimate the colloidal stability of asphalts and asphalt cross blends, aged asphalt, pyrolyzed asphalt, and heavy oil residuum; the device abides to the ASTM D6703 norm for automated Heithaus titrimetry. The samples (asphalt, heavy oil or residuum) are dissolved in toluene and titrated with iso-octane or n-heptane at controlled temperatures to determine the flocculation point and calculate the Heithaus compatibility parameters. The relevance of the FT-A in Hydrocarbon Fluid Analysis arises from the significant influence of compatibility on petroleum physical properties as well as coke formation; a highly undesirable phenomenon that causes fouling in refinery processes.
