We begin this webinar with a definition of crude oil fouling and the difference between crude oil fouling and other types of fouling mechanisms. Following this review, we discuss fouling research at HTRI by describing the High Temperature Fouling Unit (HTFU), the research testing that we conduct, and the prediction models...

HTRI 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...

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%...

Our ongoing analysis of the HTRI crude oil fouling data revealed an unacceptably high degree of scatter. A computational fluid dynamics (CFD) model of the High Temperature Fouling Unit (HTFU) test section demonstrated that the flow over the heated portion was undeveloped and asymmetrical, resulting in wall shear stress variations of...

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...
