Other typical projects include the following. First, research has been done on
the phase behavior and interfacial tensions for CO2 (and light hydrocarbon
gases) in mixtures with heavier hydrocarbons. This knowledge is targeted for
enhanced oil recovery by miscible gas injection and, in particular, on the
effects of interfacial tension on the oil displacement process. Second is a
project which deals with the phase behavior of components found in
coal-derived liquids. This work involves the systematic study of the
solubilities of light gases in heavy naphthenic and aromatic solvents. The
resultant data are designed to furnish input for the development and testing
of models to predict phase behavior in coal-fluid systems. Third is another
coal-related project addressing the adsorption of light gases such as methane,
nitrogen and carbon dioxide on coal. Detailed knowledge of the adsorption
behavior of these mixtures is important in developing improved techniques for
production of coalbed methane as an energy source. More recently, adsorption
of carbon dioxide on coal is receiving attention as a mechanism to sequester
this greenhouse gas from the atmosphere.RECENT
