Flocculation titrimeter system and trainers

The flocculation titrimeter is specifically designed to evaluate the precipitation and crystallisation conditions of asphaltenes and paraffins in very dark, undiluted crudes and oil products. The apparatus encompasses a robust stirred sample vessel combined with special fiber optic transmission probes that emit and measure the transmittance of a low intensity laser in the sample. Specifically, when asphaltene precipitation or wax crystallization occurs, the transmittance signal sharply decreases due to the presence of solid particles. Hence, the FT allows the determination of Asphaltene Onset Pressure (AOP) and Wax Appearance Temperature (WAT).
