Adsorption and flow of water in nearly dry Lurgi retorted oil shale
(Colorado State University. Libraries, 1985-02) McWhorter, D. B., author; Brown, G. O., author; Department of Agricultural and Chemical Engineering, Colorado State University, publisher
The work presented here has determined four main properties of the Lurgi spent shale. They are: 1) the critical water content above which internal drainage will occur, 2) the volume of infiltration that can be accommadated if permanent storage as a function of placement water content, 3) the rate at which water will drain if the water content is above the critical value, and 4) the rate of penetration of net infiltration through a disposal pile. To achieve the above objectives several tests have been performed. These include tests of the materials, cementing properties (hydration test, x-ray diffraction and scanning electron microscope), water holding capacity (vapor sorption and pressure plate test) and hydraulic properties (diffusivity and conductivity). The following chapters describe the testing procedures and results along with an illustrative analysis of flow in a disposal pile.
