Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

Equations of state represent the cornerstone of thermodynamic models. They have the
potential of being used for a wide range of properties, systems and conditions and thus in …

Processing crude oil of variable composition, especially due to the need to process crude oil
blends obtained from various sources, presents a tremendous process challenge. This is …

Solubility measurement of desired solid component (s) represents a primary and crucial step
of feasibility study on production process of a nanoparticle drug through supercritical fluid …

Solvent-assisted heavy oil recovery methods have gained significance in recent years. The
injected solvents can be of hydrocarbon and non-hydrocarbon chemicals or a mixture of …

In this paper, we present a systematic review of the perturbed-chain statistical associating
fluid theory equation of state (PC-SAFT) EoS for thermodynamic modeling with application in …

Asphaltene precipitation is considered a precursor of the plugging of oil wells and
subsurface equipment and is a topic of continuous interest among companies and academic …

One of the major issues in the oil industry is asphaltene precipitation. Modeling asphaltene
precipitation is still considered as a complex problem due to various characteristics of …

It is well-known that asphaltenes are a polydisperse fraction present in crude oil with a broad
distribution of sizes and molecular characteristics. However, in practice, asphaltenes are …

The asphaltene onset pressure (AOP) is a key parameter to determine the flow assurance of
oils. In this work we performed an experimental study of the PVT (pressure–volume …
