Separation and characterization of asphaltenic subfractions [PDF]
Química Nova, 2012 The structure of the various asphaltenic subfractions found in crude oil was evaluated. For this purpose, C5 asphaltenes were extracted from an asphaltic residue using n-pentane as the flocculant solvent. The different subfractions were isolated from the C5 asphaltenes by the difference in solubility in different solvents.

Practical aspects of multiphase slug frequency: An overview
The Canadian Journal of Chemical Engineering, Volume 103, Issue 6, Page 2880-2894, June 2025.Abstract Slug frequency, the number of liquid slugs passing through a point per unit of time, is an intrinsic parameter that is used to characterize multiphase slug flows in pipes. In this review we discuss practical aspects of slug frequency for industrial purposes from an examination of published literature and available experimental data. The review

Energy Science &Engineering, Volume 13, Issue 6, Page 3448-3458, June 2025.2024 was the hottest year on record and the first in which global temperature and atmospheric CO2 concentration exceeded preindustrial levels by more than 1.5°C and 52%, respectively. In response to these alarming trends, significant efforts were made to advance carbon capture, utilization, and storage technologies throughout the year.
