F-32-TR Fouling Evaluation of StreaMax™ Coating Using Desalted Crude Oil 28
October 31, 2025
This report presents the results of a test comparing the fouling performance of plain carbon steel tubes with tubes coated on the inside with StreaMax, a fluoropolymer, in thicknesses of 100 and 200 µm. In the test, desalted Crude 28 was recirculated for 30 days in the High Temperature Fouling Unit...

F-27-TR HTRI Crude Oil Fouling Standard Evaluation Test Matrix
February 02, 2022
HTRI 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, 2020
Obtaining 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%...
