Asphaltene deposition in the reservoirs, tubbing, and surface facilities causes serious flow
assurance problems with significant economic implications. Asphaltene flow assurance …

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 …

Advances in high-resolution Fourier transform ion cyclotron resonance mass spectrometry
(FT-ICR MS) enable molecular-level characterization of ultracomplex asphaltene samples …

The molecules in petroleum asphaltenes follow a molecular structure continuum similar to
the rest of the oil but differ in the formation of nanoaggregates in solution. The nature of the …

The results of the evaluation of asphaltene content in heavy crude oil depend on the solvent
chosen; and the products obtained at this evaluation have varying effects on oil viscosity. In …

A comparative study of the rheological properties for typical heavy and light crude oils of
Russian origin and their mixtures was carried out. The chemical composition of both species …

In this work, a new solvent package (named TPMDS) for asphaltene removal under static
and dynamic conditions was developed through a set of experiments. TPMDS consists of …

The use of hexamethyldisiloxane (HMDSO) for deasphalting heavy crude oil allows
precipitating several times more compounds from crude oil compared to aliphatic …

Abstract The Perturbed Chain version of the Statistical Associating Fluid Theory Equation of
State (PC-SAFT EoS) has been successfully applied to the modeling of the phase behavior …

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 …
