Abstract

The invention relates to a method for microwave treatment of aging oil. In the method, the aging oil is firstly weighed, and 50-300 ppm of aging oil treatment agent is added, then the aging oil is placed in a microwave reactor, and the nitrogen gas is replaced by nitrogen gas, and then the nitrogen gas is turned off. Start the microwave reactor, set the reaction temperature at 20-100°C, the microwave power at 400-1000W, the stirring speed at 500-1700r / min, and the microwave treatment time at 1-10min for microwave radiation. After microwave treatment, pour the aged oil into In the separatory funnel, oil and water are completely separated after settling. The invention has the characteristics of high aging oil treatment efficiency, environmental protection and no pollution, short treatment time, small occupied area, less investment, low energy consumption, easy control and the like.

Description

technical field [0001] The invention belongs to the field of aging oil treatment, and in particular relates to a method for treating aging oil by microwave method. Background technique [0002] Aged oil is a kind of crude oil sludge or ground oil with strong conductivity and difficult electrochemical demulsification. It contains a large amount of colloid and asphaltenes, which are similar to heavy oil components and have a higher content percentage. In addition, the clay contained in aged oil , FeS, naphthenic acid substances, and some mechanical impurity particles, resulting in higher viscosity, poorer fluidity, higher freezing point, higher density, and extremely difficult demulsification, which is more difficult to handle than ordinary heavy oil. On the other hand, because the aging oil in the oil field production process is difficult to handle, in order not to affect the entire production system, the aging oil can only be transferred out of the production system and left...
