【摘要】：石油在當今社會的發(fā)展中占據(jù)著至關(guān)重要的地位,社會的發(fā)展對石油能源的需求與日俱增。我國多數(shù)原油屬于高凝點原油,原油的這種物性為原油的開采與運輸帶來了一定的困難。通過添加防蠟劑的方式改變原油的低溫流動性,可以降低原油的開采難度,節(jié)約運輸成本。由于目前使用的防蠟劑存在二次污染的問題,本文通過研究兩種模擬油對安全環(huán)保型防蠟劑的性能,為原油的開采與防蠟劑的研制提供一定的理論依據(jù)。通過研究溶劑對防蠟劑效果的影響得出-35#柴油具有很好的溶解性能,并且環(huán)保污染小。采用-35#柴油作為環(huán)保型防蠟溶劑,將環(huán)保型防蠟劑作用于含蠟量不同的模擬油,通過改變反應(yīng)時間、反應(yīng)溫度、加劑量來研究對防蠟劑的防蠟效果的影響。實驗表明針對含蠟量為15%與25%的模擬油最佳反應(yīng)條件為:反應(yīng)時間為40min;反應(yīng)溫度為60℃;加劑量為300ppm。針對含蠟量為35%的模擬油最佳反應(yīng)條件為:反應(yīng)時間為40min;反應(yīng)溫度為60℃;加劑量為400ppm。將兩種防蠟劑作用于膠質(zhì)含量不同的模擬油,通過改變加劑量得出羧酸酯類防蠟劑對高膠質(zhì)含量模擬油具有較好地降凝效果,凝點下降26℃。將防蠟劑WI-1加入到膠質(zhì)含量不同的模擬油中,改變處理溫度與反應(yīng)溫度得出以下結(jié)論:反應(yīng)溫度對防蠟劑作用于模擬油的降粘效果具有較大程度的影響,處理溫度為65℃、反應(yīng)溫度為60℃時模擬油粘度最小。防蠟劑WI-1針對膠質(zhì)含量為16.11%的模擬油粘度可降低約40mm2/s。防蠟劑WI-1對不同膠質(zhì)含蠟量的模擬油在防蠟率的改善方面得出以下結(jié)論:加劑量為300ppm時,膠質(zhì)含量介于3-5%之間防蠟劑WI-1具有最佳的防蠟效果,醋酸乙烯酯類防蠟劑在加劑量為300ppm時對模擬油-2防蠟率最高為65.9%。通過正交實驗得出以下結(jié)論:從影響程度大小來說,加劑量反應(yīng)時間防蠟劑反應(yīng)溫度;防蠟劑PI40:EVA32:PMA復(fù)配的最佳比例為6:3:1,使用-35#柴油作為防蠟溶劑可以達到既環(huán)保又安全的目的;復(fù)配后的防蠟劑溶于-35#柴油,配制比例為6:3:1的防蠟劑FI-2降凝效果最佳,在加劑量為400ppm時,凝點降低24℃。在反應(yīng)時間為40min,反應(yīng)溫度為60℃,加劑量為400ppm時,將復(fù)配型防蠟劑FI-2即PI40:EVA32:PMA比例為6:3:1作用于油樣芳葡86-S-026時防蠟效果最佳,防蠟率最高可達到83.6%。
[Abstract]:Oil plays a vital role in the development of today's society, and the demand for petroleum energy is increasing with the development of society. Most of the crude oil in China belongs to high freezing point crude oil. This physical property of crude oil has brought some difficulties to the exploitation and transportation of crude oil. By adding a wax-proof agent to change the low temperature fluidity of crude oil, it can reduce the difficulty of crude oil exploitation. Saving transportation cost. Because of the problem of secondary pollution of the wax inhibitor used at present, this paper studies the performance of two kinds of simulated oil to the safety and environmental protection type wax inhibitor. This paper provides some theoretical basis for the exploitation of crude oil and the development of waxproof agent. By studying the influence of solvent on the effect of waxproof agent, it is concluded that the diesel oil has good solubility and little environmental pollution. By changing the reaction time and reaction temperature, the environmental antiwaxant was applied to the simulated oil with different wax content. The optimum reaction conditions for the simulated oil with wax content of 15% and 25% were as follows: reaction time 40 min, reaction temperature 60 鈩，
