|
摘要
对延长石油集团煤油共炼装置产生的共炼残渣进行原料特性分析,并对其理化性质及危害性进行了评价。基于煤油共炼残渣的特性,提出了煤油共炼残渣与多元料浆气化技术相结合,实现煤油共炼残渣的资源化高效清洁利用的思路,并详细介绍了技术路线和研究情况。多元料浆气化技术能使煤油共炼残渣中的有机物在高温下得到有效分解,实现污染物消减;能使无机物在熔融条件下与原料煤的灰渣形成安全稳定的玻璃化产物,有利于最终的处置利用。结果表明将煤油共炼残渣作为部分原料进行多元料浆气化反应,能够实现对残渣的资源化处理,气化指标良好。
The characteristics of the coal-oil coprocessing residue produced in the coal-oil coprocessing unit of Yanchang Petroleum Group were analyzed, and its physical and chemical properties and harmfulness were evaluated.Based on the characteristics of coal-oil coprocessing residue, the idea of combining coal-oil coprocessing residue with multi-component slurry gasification technology to realize efficient and clean utilization of coal-oil coprocessing residue was put forward, and the technical route and research situation were introduced in detail. The multi-component slurry gasification technology can effectively decompose organic matter in coal-oil coprocessing residue at high temperature to realize pollutant reduction. It can also make inorganic matter form a safe and stable vitrification product with the ash of raw coal under the melting condition, which is beneficial to the final disposal and utilization. The results show that using coal-oil coprocessing residue as part of the raw material to carry out multi-component slurry gasification can realize the resource processing of residue, and the gasification index is good.
