Content Abstract
the intermediate emulsion oil of the oil field spill-sink tank is a complex emulsion with about 70% water content. The formation and continuous thickening of this part of emulsified oil will affect the normal operation of oil and water separation in the tank. At present, the domestic oil field for this part of the emulsified oil has not yet found a cost-effective method of breaking milk, the use of conventional thermochemical milk breaking is difficult to effectively separate its oil and water, usually regularly pumped out of this part of the emulsified oil, into the drying pool or thrown away at will, which not only wastes a lot of crude oil, but also causes a lot of environmental pollution. In view of the problems in the process of emulsified oil breaking, a new process of microwave milk breaking-centrifugal separation is proposed through the summary of the existing oil-water separation technology and the comparison of various milk-breaking schemes.
, the technical index of the process to deal with emulsified oil in the middle layer of the settlement tank is superior, which can effectively solve the problem of breaking milk in this part of emulsified oil. In this paper, a new process of microwave milk breaking-centrifugal separation is studied, including microwave milk breaker and BKD-1000 three-phase vertical centrifuge. The effect of the process parameters of the continuous operation of the process on its performance was studied, and the laboratory simulation test of microwave milk breaker and the industrial test of BKD-1000 three-phase vertical centrifuge were carried out. The experiment determines the effect of microwave milk breaking-centrifugal separation on the processing effect, designs 800W tunnel box-type continuous microwave milk breaker on the basis of static test, and optimizes the structural parameters of microwave milk breaker with water and simulated emulsified oil respectively, and systematically studies the process parameters affecting continuous milk breaking, and determines the best process conditions.
the numerical simulation of the distribution of electric field in 800W microwave milk breaker, the scale amplification research of microwave milk breaker is carried out, and the principle of scale amplification is put forward, and the 5kW microwave milk breaker is designed accordingly. Based on the analysis of the characteristics of the existing centrifuges, the design scheme of the BKD-1000 three-phase vertical centrifuge suitable for oil, water and slag separation is proposed, which has the characteristics of the overall rotation of the separation zone, and the fluid obtains a higher centrifugal acceleration. The laboratory simulation test of microwave milk breaker showed that using microwave milk breaking-centrifugal separation process to treat simulated emulsified oil can make the simulated emulsified oil water effectively separated, the water content of oil was reduced from 50.0% to 5.51%, and the recovery rate of oil reached 98.33%. The industrial test of BKD-1000 three-phase vertical centrifuge shows that the treatment of oil-containing sewage in dry oil field can reduce the water content of oil to 3.56%, the recovery rate of oil reaches 85.26%, and the concentration of slag discharge reaches 62.18%, which meets the requirements of industrial testing put forward on site.
