Report on 10-ton retort tracer testing: tests S76 through S79
Technical Report

OSTI ID:5396645
An oil shale retort with contrasting permeability regions has been studied using gas tracer techniques. The Western Research Institute's 10-ton retort was loaded with oil shale of various size ranges resulting in different void fractions. Four retorting and tracer runs were performed on the retort. For each run, tracer injections were made into the main air flow inlet and into taps near the top of the retort. Detection taps were located at four levels in the retort with five taps on each level in tests S76 through S78. There were six taps on each level in run S79. The oil shale rubble bed was configured with a cylindrical nonuniform region on the center line of the retort in tests S76 through S78. In run S79 two side-by-side regions with differing bed properties were tracer tested and retorted. Response times were calculated from the tracer response curves. The tracer response times from in-bed tracer tests correlate with oil yield and with bed properties. Response times from the inlet-to-outlet tracer tests correlate with total oil yield through a first-order relationship with sweep efficiencies. 8 refs., 6 figs., 1 tab.
