Study on Morphology and Structure of Wax Crystals in Waxy Crudes at Apex Temperature of Wax Precipitation
Abstract:
The apex temperature of wax precipitation was measured with fractal dimension characterizing the wax crystal morphology, and Differential Scanning Calorimetry (DSC), respectively. The experimental result revealed that the concentration of precipitated wax in virgin waxy crudes had the strong positive correlation with the fractal dimension of wax crystals. At the apex temperature, the wax crystals changed from tiny microscopic spots to clear and visible ones, with their morphology and structure becoming more intricate.
