【摘要】 含油污泥是石油工业的主要污染物之一,其处理一直是油田以及石油企业的难题,如果处置不当,将造成严重的环境污染。热解技术是一种在无氧或缺氧的条件下,将油泥中的重质组分转化为轻质组分,并加以回收的新的含油污泥处理技术,可以更为彻底地处理含油污泥,且具有二次污染程度小、能量可回收利用的特点,是一种应用前景较广的处理方法。本文对国内外含油污泥热解技术的研究进展进行了总结,并重点介绍了温度、加热速率、停留时间、热解催化剂对于含油污泥热解效果及产物的影响,同时还阐述了热解动力学模型的拟合方法,分析了热解能量流动过程以及目前工业中应用比较广泛的热解设备,并指出未来含油污泥热解技术可能的发展方向,以期对含油污泥热解技术的发展提供参考。更多还原

【Abstract】 Oily sludge is one of the main pollutants in petroleum industry. Its treatment has been a difficult problem for oil fields and oil enterprises. If it is not properly disposed of, it will cause serious environmental pollution. Pyrolysis technology is a new treatment technology of oily sludge, which converts heavy components into light components and recycles them under the condition of no oxygen or anoxia. It can treat oily sludge more thoroughly and has the characteristics of less secondary pollution and energy recycling. It is a treatment method with wide application prospects. The research progress of pyrolysis technology of oily sludge at home and abroad is summarized in this paper. The effects of temperature, heating rate, residence time and pyrolysis catalyst on pyrolysis efficiency and products of oily sludge are mainly introduced. The fitting method of pyrolysis kinetic model is also described. The process of pyrolysis energy flow and pyrolysis equipment widely used in industry are analyzed. The possible development direction of pyrolysis technology of oily sludge in the future was put forward in order to provide reference for the development of pyrolysis technology of oily sludge.更多还原
