The Risk Analysis and Control Research Of Oil Shale Processing

The oil shale resources is abundant in China, shale oil can be obtained by retorting the oil shale, which is an important supplement to the future energy, it can directly be used as fuel or produce high-quality fuel and chemical products through further processing, With the accelerating utilization of oil shale development, its safety and environmental issues attract more and more people's attention. In the side of safety, oil shale processing involves a lot of flammable, explosive, toxic and hazardous substances, and due to human and equipment factors, there exists many dangers. such as the pile of oil shale, semicoke and incomplete combustion shale ash will self-ignite or cause fire. retort furnace will explode if the air excess. Environmental aspects, the good and bad are intermingled in enterprises, the comprehensive utilization of oil shale in large enterprises is higher, but some small enterprises use the old technology and equipment because of financial and technical problems, not only low utilization of the resource, there is a larger environmental pollution problems.

Oil shale processing risk analysis focus primarily on environmental risks, less on safety risk analysis, which primarily focus on retort furnace safety risk analysis, not consider the entire process. Otherwise, safety risk analysis and environmental risk analysis contents are repetitive and confusing. Therefore, combing their characteristics, conduct a comprehensive risk analysis of the oil shale processing. identify shale oil, ammonia, hydrogen sulfide, pyridine, phenols and other poisonous and harmful substances, analyze their harmfulness and the risk of devices, Finally, put forward the corresponding preventive measures.

The processing and utilization of oil shale brings the gospel to the world, but its impact on society is enormous. at the time of our country encourage and accelerate the comprehensive utilization of oil shale, enterprises should strengthen the oil shale processing safety and environmental management, so that the development and utilization of the oil shale can achieve safety , environmental and economic benefits, and it plays an important role to achieve sustainable development of unconventional oil and gas resources.
