A continuous flow apparatus was applied to measure the phase equilibrium at 523 K and 573 K. The performance of analysed with determination vapor pressures water temperatures ( T = 453 473 K). measured deviated from literature values less than 1 %. Vapor n -dodecane, -hexadecane phenol were 523–623 K) and, bubble point -dodecane + pure components compared values. Relative pressure value 2 % for...

Abstract This research study aims to conduct a comparative performance analysis of different scaling equations and non-scaling models used for modeling asphaltene precipitation. The experimental data carry out this are taken from the published literature. Five which include Rassamadana et al., Rassamdana Sahimi, Hu Gou, Ashoori log–log were applied in two ways, i.e., on full dataset partial dat...

The phase behavior of perfluoro-(n)-alkane + (n)-alkane binary mixtures is of particular interest given their unexpected large positive deviations from Raoult’s law. Binary mixtures of perfluoromethane + (n)-alkanes from methane to heptane are studied here, illustrating the continuous change in phase behavior from type II to type III that these systems exhibit. Some symmetrical systems that dis...

The study of water–hydrocarbon phase equilibria is very important for both scientific and industrial purposes. This work a thorough investigation the predictive capability SAFT-VR Mie equation state (EoS) aqueous hydrocarbon equilibria, including n-alkanes, alkenes, cycloalkanes, branched alkanes, aromatic hydrocarbons. For alkenes alkyl benzenes, induced association (solvation) with water cons...

By relying on optics for providing the transduction of ultrasound, laser-ultrasonics brings practical solutions to a variety of nondestructive evaluation problems that cannot be solved by using conventional ultrasonic techniques based on piezoelectric transduction (1,2]. Laser-ultrasonics uses two lasers, one with a short pulse for the generation of ultrasound and another one, long pulse or con...
