In order to solve the problems related with processing low-quality Liaohe highly sour crude, the Liaohe Petrochemical Company has explored the possibility in optimizing the processing of highly sour crude by adopting different process schemes depending upon the properties of the highly sour crude. The Liaohe naphthenic-base crude oil with low freezing point is earmarked for manufacture of naphthenic lube oils and heavy traffic paving asphalt, while the extra-heavy Liaohe crude with high acid number is routed directly to delayed coking unit coupled with corresponding corrosion preventing measures, resulting in tackling the problem of equipment corrosion arising from refining of Liaohe highly sour crude to obtain light distillates from Liaohe heavy crude through a short process scheme. 相似文献

对辽河油田曙光一区高粘原油性质作了分析评价。结果表明,此原油粘度极大,凝点高,初馏点高,无汽油馏分,柴油馏分收率仅为7.19%,此原油不适合作为生产汽、煤、柴油的一般加工工艺的原料。但此原油蜡含量很低,胶质沥青质含量较高,属低硫环烷基原油,是生产重交通道路沥青的优质原料。 相似文献

选取油源相似、性质不同的塔河4种原油为原料,对其性质进行分析;对不同性质原油进行蒸馏分别制备出针入度在80~110(0.1mm)范围内的沥青样品,按照SH/T 0522中的分析项目对其进行性能分析。结果发现:①原油的密度可以表征原油作为生产沥青原料的性能;②沥青性质与所加工原油性质密切相关,在针入度满足要求范围内,随着原油密度的增加,沥青延度(25 ℃、15 ℃)逐渐降低,软化点逐渐升高;③当原油密度达到一定程度(0.94 g/cm3左右),所制备沥青针入度接近100号沥青产品指标上限时,沥青的各项性能均能满足100号沥青产品的指标要求;但是,当沥青的针入度接近100号沥青产品指标下限时,沥青的25 ℃延度不能满足100号沥青产品的延度指标要求; ④在所选原油中,当原油密度超过0.95 g/cm3时,用蒸馏工艺难以生产出合格的100号道路沥青产品。 相似文献

低硫超稠油水热裂解反应的研究 总被引:1,自引:0,他引:1
研究了反应温度、反应时间、加水量对辽河曙一区超稠油水热裂解反应的影响。结果表明,随反应温度、反应时间和添加物料中水油比的增加,水热裂解反应后油样的饱和份、芳香份的含量逐渐增大,沥青质、胶质含量逐渐减小;在反应温度为240℃、反应时间24小时、添加的水油质量比为0.5时,超稠油水热裂解反应基本完成,50℃粘度由超稠油原样的147.5Pa·s降低到115.4Pa·s,平均相对分子量由超稠油原样的674降低到550。由此可知,含硫量仅为0.45m%的辽河曙一区超稠油能够通过水热裂解反应降低其粘度,实现降粘开采。 相似文献

The characteristics of the high viscous crude from No. 1 Shuguang Zone of Liaohe Oil Field are similar to those of residue distillates of general crude such as high density(ρ 20=0·9977 g.cm-3),high viscidity υ 100= 1223·9 mm2.s-1) and high carbon/hydrogen ratio. This oil contains less wax, but rich in resin and asphalt, which belongs to low sulfur naphthene-base crude oil and can be used as feedstock to produce high paving asphalt. But now it is used as fuel after emulsificating. In order to make full use of this oil and resolve the problem of paving asphalt demand-supply, various paving asphalts conforming to GB50092-96 standard were produced by blending vacuum residue of the high viscous crude from No.l Shuguang Zone of Liaohe Oil Field and waste oil which is rich in aromatics and poor in wax. The laboratory test results show that modified paving asphalts have good low-temperature properties and antiaging feature. 相似文献

Abstract The ever-increasing world energy demand would require the use of all hydrocarbon resources available, especially heavy and extra-heavy crude oils in the near future. However, transportation of these crudes is very difficult due to their high viscosity and low mobility. There are many different methods to reduce heavy crude oil viscosity. Some of these methods are heating, blending, water-in-oil emulsion formation, upgrading, and core annular flow. But each of these methods has several problems. The aim of this research is to investigate a new method to reduce viscosity for pipeline transportation. In this method asphalt molecules, which are mainly responsible for high viscosity, are aggregated temporarily to micronized clusters while going through a pulsed electric field, causing a reduction of the viscosity. This method does not change the oil's temperature and is very suitable for underwater pipelines. The authors applied electric fields in the range of 0.5 to 1.8 KV/mm an Iranian heavy crude oil and viscosity reduction up to 7% was observed. 相似文献
