Retorted Oil Shale Disposal Research
نویسنده
چکیده
Although the retorted, or processed, shale represents the largest by-product from oil shale retorting operations, results from detailed studies indicate that it can be managed in an environmentally acceptable manner. Laboratory and field tests have demonstrated the following properties: using normal vehicular traffic; cementation strength to 1480 kPa, using only retorted shale and optimum water; permeabilities as low as 1 x lo-’ cm/s, using proper handling techniques. tests have shown that dusting, auto-ignition, and leaching pose no special problems. These research results indicate that properly managed retorted shale exhibits the properties of a low-grade cement. Thermal reactions occurring during retorting and the chemical composition of retorted shale are related to the cementlike physical properties. compaction to 1600 kg/m3,

Characterization Of Oil Shale Residue And Rejects From Irati Formation By Electron Paramagnetic Resonance∗
In this study, sedimentary organic matter of oil shale rejects, calschist, shale fine and the so called retorted shale from Irati formation was characterized. EPR was used to analyse the samples regarding loss of signal in g = 2.003 associated to the organic free radical with the calcined samples and washing with hydrogen peroxide. The radical signal was detected in all samples, however, for th...
متن کاملConverting oil shale to liquid fuels: energy inputs and greenhouse gas emissions of the Shell in situ conversion process.
Oil shale is a sedimentary rock that contains kerogen, a fossil organic material. Kerogen can be heated to produce oil and gas (retorted). This has traditionally been a CO2-intensive process. In this paper, the Shell in situ conversion process (ICP), which is a novel method of retorting oil shale in place, is analyzed. The ICP utilizes electricity to heat the underground shale over a period of ...
متن کاملBiological effects of raw and processed oil shale particles in the lungs of laboratory animals.
Environmental and occupational health concerns will have an effect on the developing oil shale technologies. The mining and crushing of large volumes of rock will be a characteristic of at least some of these technologies, and above ground disposal of proceessed shale will require adequate control measures. Exposure by inhalation to the dusts that may arise from shale oil technologies may prese...
متن کاملImpacts of shale gas wastewater disposal on water quality in western Pennsylvania.
The safe disposal of liquid wastes associated with oil and gas production in the United States is a major challenge given their large volumes and typically high levels of contaminants. In Pennsylvania, oil and gas wastewater is sometimes treated at brine treatment facilities and discharged to local streams. This study examined the water quality and isotopic compositions of discharged effluents,...
متن کاملComposition of bacterial community in enrichment cultures of shale by-products from Irati Formation, Brazil.
We examined microbial communities from enriched fine and retorted shale particles using sequencing of V4 variable region of 16S rRNA. High number of microbial genera was found in both enriched shale by-products that were dominate by Actinobacteria, Firmicutes and Proteobacteria, showing differences due to microbial colonization after the pyrolysis process.
