【摘要】：含蠟原油因其蠟組分的存在而導致原油在低溫環(huán)境中黏度變大、流動性變差,而在管輸的過程中,蠟晶的析出會降低管道的輸送能力、甚至有堵塞管道的威脅。本文利用已發(fā)現的一株嗜蠟菌,利用其發(fā)酵液降解含蠟原油中的蠟組分,實驗證明處理5天后的原油含蠟量降低、表觀黏度下降,偏光顯微鏡觀察油中蠟晶結構明顯變小而分散。軟件ImageJ對顯微鏡照片處理后測量得到:最大蠟晶粒徑從609.1μm下降至72.1μm;平均費雷特徑大小從79.1μm下降到50.3μm。
[Abstract]:Due to the presence of waxy components in waxy crude oil, the viscosity and fluidity of crude oil in low temperature environment become larger and worse. In the process of pipeline transportation, the precipitation of waxy crystals will reduce the transportation capacity of pipeline and even threaten to block the pipeline. In this paper, the waxy component of waxy crude oil was degraded by the fermentation broth of a strain of waxy bacteria. The experimental results showed that the wax content and apparent viscosity of the crude oil decreased after 5 days of treatment. The crystal structure of wax in oil was obviously smaller and dispersed by polarizing microscope. The results showed that the maximum particle size of wax crystal decreased from 609.1 渭 m to 72.1 渭 m, and the average Flatt diameter decreased from 79.1 渭 m to 50.3 渭 m.
