Research and application of harmless treatment technology for solid waste from oil shale retorting
The solid by-products of oil shale retorting are oil sludge and waste residue.Oil sludge is a dangerous waste.In order to ensure the green development of oil shale production,the research on harmless treatment technology of retorting solid waste was carried out.The results show that the sludge can be fully utilized by rapid solidification and distillation technology,oil-water-sand separation technology The zero leakage technology of shale retorting residue field with multi-layer protection can ensure the waste residue to be stored with zero pollution,thus realizing high efficiency,clean and controllable in the whole process of oil shale processing and utilization.
