摘要
热相分离技术是一种将油基岩屑加热至一定温度,使油、水组分汽化分离出来的新型综合治理技术。以某大型油基钻井岩屑综合利用工程为依托,分析热相分离技术的工程设计与应用效果。结果表明:热相分离技术可将净化残渣的含油量降至0.1%~0.2%,基础油的平均回收率为94.12%,每年回收基础油量约为4800 t;净化后的固体残渣不具备腐蚀性、浸出毒性等危险特性,可用于制砖或建筑材料。热相分离技术是一种工程效益和环境效益俱佳的综合利用处理技术,具有很高的推广价值。
Thermal phase separation technology is a new comprehensive treatment technology which heats oil based cuttings to a certain temperature to vaporize oil and water components.Based on a large oil based drilling cuttings comprehensive utilization project,the engineering design and application effect of thermal phase separation technology were analyzed.The practice shows that thermal phase separation technology can reduce the oil content of purified residue to 0.1~0.2%,the average recovery rate of base oil is 94.12%,and the annual recovery of base oil is about 4800 tons;the purified residue does not have corrosive,leaching toxicity and other dangerous characteristics,and can be used for making bricks or building materials.Thermal phase separation technology is a comprehensive utilization and treatment technology with excellent engineering and environmental benefits,which has a high promotion value.
