应用均匀设计法研究原油的微波破乳脱水规律

原油含水不仅给油田生产带来一系列困难,还给原油的储存、输送以及炼油厂的加工造成不利影响.因此,原油脱水成为油田生产过程中不可缺少的环节,研究高效、低耗、便捷的破乳脱水技术具有重要意义.利用微波辐射处理油包水型乳化液具有常规破乳脱水方法不可比拟的优越性.应用均匀设计方法研究了微波功率、微波作用时间和乳化液含水率与微波处理后原油脱水率之间的关系,并拟合出它们之间的经验关系式,分析了微波对含水原油的破乳脱水规律.研究表明,乳化液含水率对微波破乳的效果影响最大,含水率越高,脱水率越高;微波功率与辐射时间的乘积越大,即微波辐射能量越大,破乳效果越好.

Study on the law of microwave demulsification dehydration using uniform design method

Water-bearing of crude oil causes some difficulties not only to the production of oilfields but also to the storage,transportation and refinement of crude oil.Therefore,the study of high-efficacy,low-cost and easy-using crude oil demulsification dehydration techniques is very important.The demulsification dehydration technique of W/O emulsion using microwave radiation has imcomparable advantages with other demulsification dehydration techniques.The relationship between dehydrated rate of crude oil and power of microwave,radiation time of microwave and water cut of crude oil emulsion is experimentally studied by means of uniform design method,and the relational expression is obtained by fitting.The results show that,the water cut of crude oil emulsion has the greatest effect on the result of microwave demulsification dehydration,the higher the water cut,the higher the dehydrated rate;the greater the product of microwave power with radiation time(that is,the greater the radiation energy of microwave),the better the result of microwave demulsification dehydration.
