摘　　要：以某采油厂含油污泥为处理对象,开展间歇式热解技术的应用研究,主要进行了含油污泥热解特性分析和加热时间、加热温度T参数优化现场试验。现场试验结果表明,含油污泥热解过程分为干燥阶段(50℃≤T<180℃)、轻质油组分挥发阶段(180℃≤T<385℃)、重质油组分热解阶段(385℃≤T<550℃)、半焦化及无机矿物质分解阶段(T≥550℃),掌握了不同的含油污泥原料性质,确定了最佳热解时间为25~40 h,最佳热解温度为400℃,处理后含油污泥达到DB23/T 3104—2022《油田含油污泥处置与利用污染控制要求》,且可低成本运行。This study focuses on the application of batch pyrolysis technology for treating oil-contaminated sludge from an oil extraction plant.The research primarily includes an analysis of the pyrolysis characteristics of the oil-contaminated sludge and the optimization of heating time and temperature T parameters through field experiments.The results of the field tests indicate that the pyrolysis process of oil-contaminated sludge can be divided into several stages:drying stage(50℃≤T<180℃),light oil component volatilization stage(180℃≤T<385℃),heavy oil component pyrolysis stage(385℃ ≤T<550℃),and semi-coking and inorganic mineral decomposition stage(T≥550℃).By understanding the properties of different oil-contaminated sludge materials,the optimal pyrolysis time was determined to be 25-40 hours,and the best pyrolysis temperature was found to be 400℃.After treatment,the oil-contaminated sludge met the requirements of DB23/T 3104—2022 “Pollution Control Requirements for the Disposal and Utilization of Oilfield Oil-Contaminated Sludge”,with the process operating at a low cost.
