| Popis: | For 20 years, Heat Transfer Research, Inc. (HTRI), has conducted dedicated, ongoing research into crude oil fouling behavior, specifically on developing test methods to measure fouling resistance over time and comparing fouling tendencies of different crude oils. More than 250 test runs with nineteen crude oils have been conducted. While current methods are sufficient for comparative fouling studies, general methods to predict fouling tendency remain elusive. Recent initiatives have focused our efforts on chemical characterization to screen crude oils and blends for fouling tendency, as well as on identifying thresholds for low fouling. Increasing the shear stress on the heat transfer surface as much as possible can mitigate heat exchanger fouling. Long-term success in controlling fouling depends upon a deeper understanding of the chemical characteristics of an individual crude oil and sound heat exchanger design practices. Current predictive fouling models are limited in their application, but improvemen... |
