An analytical apparatus has been designed to study the phase behavior of fluid mixtures of relevance to CO2-enhanced oil recovery and carbon dioxide storage in deep aquifers or depleted oil fields.
Such default approaches are often adopted out of necessity for example, to bridge data gaps about mixtures of relevance or to deal with extrapolation issues such as from high to low dose or between species (U.S. EPA 1986 , 1989 2000).
The SAFT-VR DFT formalism, which has recently been extended to mixtures [F. Llovell et al., J. Chem. Phys. 133 (2010) 024704], is applied to the interfacial properties of a wide variety of binary mixtures that are of relevance to enhanced oil recovery and carbon dioxide sequestration.
The purification of most of the fluid mixtures of industrial relevance is performed in distillation columns trains.
This view is based on two premises: first, that NOAELs are a good approximation of "safe" doses of pollutants; and second, that the distinction between "similarly" and "dissimilarly" acting chemicals in a mixture is straightforward and of relevance to the risk assessment issue at hand.
Our studies provide a systematic basis for the investigation of mixtures that affect endpoints of relevance to genotoxicity and show that their effects are largely additive.
We present and discuss two-phase flow models to simulate transient flow of CO2-rich mixtures in pipes, which is of relevance for design, operation and safety.
Thus, social bookmarking and tagging, as described in [45], are sui generis mixture of both implicit and explicit relevance feedback.
A second issue of relevance to regulatory toxicology concerns the question of mixture effects at low doses.
Such a problem is of relevance to combustion systems with non-homogeneous air/fuel mixtures or recirculation of the burnt gases.
