Temperature-Dependent Wax Precipitation Characteristics in Gas Condensates: Composition, Aggregation, and Crystallization Patterns.

ABSTRACT: This study investigates the characteristics of the wax precipitation activity in the condensates. The patterns of wax precipitation are elucidated by analyzing the composition and amount of precipitate produced at various temperatures, verifying the influence mechanism of factors such as condensate composition and temperature on wax separation. The findings reveal that a decrease in the temperature enhances the contact of wax molecules by reducing their thermal motion, leading to wax particle precipitation. This also weakens the Brownian motion of precipitated wax, further promoting their aggregation and subsequent deposition. Consequently, the amount of wax precipitate increased as the temperature drops. Moreover, an increase in asphaltenes and resins in the condensates raises the critica
