The precipitation of asphaltenes in two Mexican crude oils was measured using a
combination of high‐pressure isothermal expansion and atmospheric titration with n …

A thermodynamics analysis of gasification process is performed using the Gibbs energy
minimization approach through Lagrange multiplier method. Three different methods of …

This paper presents a new method for multiphase equilibria calculation by direct
minimization of the Gibbs free energy of multicomponent systems. The methods for …

Efficient and robust phase equilibrium computation has become a prerequisite for successful
large-scale compositional reservoir simulation. When knowledge of the number of phases is …

A pre® iously described molecular-thermodynamic framework, based on colloid theory, is
used to correlate experimental asphaltene-precipitation data at high-temperature and …

Phase equilibrium calculations are often involved in the design, simulation, and optimization
of chemical processes. Reported methods for these calculations are based on either …

CO2 injection into an oil reservoir at low temperature can lead to the formation of three
hydrocarbon phases. Key challenges persist in the development of phase equilibrium …

Tabu (or taboo) search (TS) has been successfully applied to combinatorial optimization but
it has not been used for global optimization of many continuous functions including phase …

In this paper, we propose a new method for phase stability analysis with cubic equations of
state by minimization of the tangent plane distance (TPD) function. A global optimization …

Wax precipitation for gas condensate fluids was studied in detail with a thermodynamic
model. It was found that the precipitated wax phase can exhibit retrograde phenomena …
