Abstract
Reclamation and impact analysis of retorted oil shale piles will require prediction of water and solute transport rates over the entire solution content range, down to and including the relatively dry region. In such dry materials, vapor transport of water affects the transport of solutes. Experimental measurements of transport coefficients in relatively dry oil shale have brought forward longstanding questions concerning the mechanics of combined liquid-vapor flow. Principal among these is the apparent inability of porous media to transport solutes at low solution contents. In an attempt to ensure proper interpretation of experimental data, a new theory of solute transport by combined liquid-vapor flow has been developed, and new analytical solutions for transient flow have been obtained. The solutions show that the relative magnitudes of the separate transport coefficients produce many of the flow features seen in experimental data, and significant liquid transport can occur in regions without apparent solute transport. This development is new and represents an addition to the understanding of solute transport. These methods and results can be applied to other problems in multiple phase transport, such as hazardous waste disposal, mine reclamation, and soil leaching.
