F-27-TR HTRI Crude Oil Fouling Standard Evaluation Test Matrix
February 02, 2022HTRI developed a standardized crude oil fouling test matrix that covers industry-relevant ranges of flow, bulk temperature, and wall temperature. The test matrix provides a more complete picture of a crude oil’s fouling behavior in the High Temperature Fouling Units (HTFUs). This report summarizes the design of the HTFUs, the identification...
F-26 Evaluation of Methods to Predict Hydrocarbon and Crude Oil Viscosities from Low Temperature Measurements
July 27, 2020Obtaining viscosity measurements at elevated temperatures and pressures is challenging. HTRI evaluated several viscosity correlations to determine the best model for hydrocarbons. We also examined a viscosity-density correlation using limited density data. From the initial evaluation, the Walther model proved to be the most promising for extrapolation, predicting viscosity within ±30%...
Research Update: Design and Construction of the Rotating Fouling Unit
January 16, 2017HTRI currently runs fouling experiments on the High Temperature Fouling Unit (HTFU) which recirculates a 27 liter sample of crude for periods up to one month. As we plan to expand our crude oil fouling test program, we are investigating alternate test methods to screen crude oil fouling with smaller sample...
