鉴于利用玉门炼油厂原料(一种石蜡基混合原油)的减压渣油和减压渣油的溶剂脱油沥青不能直接生产出合格的道路沥青,根据优质道路石油沥青性能对组成分子的基本要求,利用多元调合法间接试制道路石油沥青,研制出了能生产出包括中石化集团公司2号高等级道路沥青(Q/SHR004-1998)在内的多种牌号道路沥青配方。初步探讨了在减压渣油中调入适量催化裂化油浆,并经溶剂脱沥青工艺直接生产道路沥青的可行性。试验结果表明,在脱沥青油收率增加的同时,脱油沥青的道路石油沥青性质明显改善,因此可优化炼油厂的工艺组合。研究方法对于加工石蜡基或非石蜡基原油的炼油厂具有指导意义。 相似文献

镇海炼化公司以科威特原油为原料,通过常减压直馏生产出合格的70号A级沥青近600kt。2010年为拓宽A级沥青生产原油资源,开始向科威特原油掺炼巴士拉原油的加工方案转变,按一定比例掺炼后A级70号沥青产品质量较好,掺炼比增加到50%时,由于软化点较低,不宜用于生产A级50号沥青。 相似文献

针对润滑油基础油相继出现的黏度指数降低、酸值升高等问题,跟踪分析了润滑油基础油质量,认为原油的变化是造成润滑油基础油质量变化的根本原因;基础油组成中烷烃含量降低,芳烃和环烷烃含量上升是其酸值上升和黏度指数下降的内在原因。 相似文献

The high viscous crude oil for Shuguang No. 1 zone of Liaohe oilfield has the characteristics of high density (ρ20 = 0.9977 g.cm-3), high viscidity (ν100 = 1,223.9 mm2.s-1), and high solidifying point (SP = 48°C), which belongs to low sulfur naphthene-base crude oil. The comprehensive evaluations indicate that this oil has no gasoline fraction and the diesel oil is only 7.19%. In addition, the lubricating oil distillate is not suited to produce lubricating oil and heavy oil is not good feedstock for catalytic cracking. However, the low wax and high resin, as well as asphaltene content, make it an ideal raw material for producing paving asphalt. The vacuum residue of this crude acted as base oil and three kinds of waste oil with high aromatics and low wax content were selected as blenders. Various brands of high-grade paving asphalts meeting GB/T15180-94 (China) specification were produced by blending method. The blending effects were investigated and corresponding mathematics models were set up. 相似文献
