Toxic trace elements and oil shale production

An interdisciplinary, multiuniversity research program sponsored by ERDA is investigating the potential for release of harmful amounts of trace elements into the environment by the extraction and processing of oil shale. Scientists from the University of Colorado, Colorado State University, and the Colorado School of Mines are studying the background levels of trace elements in natural materials, the mass flow through oil shale retorts, the uptake of trace elements by plants, and the leachability of trace elements in retorted shales and disturbed soils. Because a 50,000 bpd plant will process about 73,000 tons/day of shale, the amount of trace elements flowing through the system can be prodigious. When this is scaled up to a proposed million barrels per day industry, the quantities are even more impressive. In one year, such an industry would be depositing spent shale containing 16,000 tons of As, 800,000 tons of F, and 8,000 tons of Mo. The loss of even a small fraction of these elements could have a significant environmental impact. The group has focused on As, Mo, Se, F, and B because of the alkaline nature of the area and the processes involved.
