【摘要】：消油剂的合理使用是海洋溢油应急处置的一种有效手段。本研究选取渤海产蓬莱19-3和旅大10-1原油,开展消油剂对原油乳化效果测试的波浪槽模拟实验。以消油剂乳化率和油滴中值粒径为测试指标,设置不同波浪条件和剂油比,考察两种不同消油剂对渤海原油的乳化效果。结果表明,消油剂A、消油剂B对两种原油的乳化率均随剂油比和波高条件的增大而增加,油滴中值粒径随剂油比和波高条件的增大而减小。消油剂B与消油剂A相比表现出较高的乳化能力,在实验条件下对蓬莱19-3原油的乳化率最高可达52.9%,油滴中值粒径最低可达12μm。对于不同类型原油,消油剂的乳化分散效果不同。本研究结果可为溢油应急处置中消油剂效用效果预测以及应急方案的制定提供依据。
[Abstract]:The rational use of oil suppressant is an effective method for marine oil spill emergency disposal. In this study, we selected Penglai 19-3 and Lunda 10-1 crude oil from Bohai Sea to carry out wave trough simulation experiment to test the emulsifying effect of oil suppressant on crude oil. The emulsifying effect of two kinds of oil suppressants on Bohai crude oil was investigated by setting different wave conditions and the ratio of agent to oil with the emulsification rate and the median particle size of oil droplet as the test index. The results show that the emulsifying efficiency of oil suppressant A and oil suppressant B increases with the increase of the ratio of oil to oil and the wave height, and the median particle size of oil droplet decreases with the increase of the ratio of oil to oil and the wave height. The emulsifying ability of oil suppressant B is higher than that of oil suppressant A. under the experimental conditions, the emulsification rate of Penglai 19-3 crude oil can reach the maximum of 52.9 and the lowest median particle size of oil droplet can reach 12 渭 m. For different types of crude oil, the emulsifying and dispersing effect of oil suppressant is different. The results can be used to predict the effect of oil suppressant in oil spill emergency disposal and to make emergency plan.
