  • Overview of Vapor Infusion Technology

    September 02, 2020
    Overview of Vapor Infusion Technology Vapor Infusion Overview Applications Studies Contact Us Vapor Infusion The vapor infusion system injects (infuses) vaporous treatment into the water flow stream of heat exchangers and process equipment, thus creating a profusion of bubbles in the flow stream. These bubbles mechanically prevent and chemically reduce fouling...

  • TechTip: Modeling Plate-and-Shell Heat Exchangers using Xphe

    July 29, 2020
    This webinar briefly reviews HTRI research on plate-and-frame heat exchangers and plate-and-shell heat exchangers (PSHEs), focusing on the geometry differences and similarities between the two types. Xphe® is a module in Xchanger Suite® for modeling plate-and-frame heat exchangers. Using an example case, we will discuss how to use Xphe to model a PSHE. Additionally, we identify the key...

  • 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%...
