Can that company process Russian oil? I heard in the news that CNPC signed a contract for 300 million tons of crude oil

Does anyone know what kind of crude oil Rosneft uses? This post was last edited by chengkang on 2009-2-23 18:41]

It should be Daqing or the companies that process Daqing crude oil; here, we processed Daqing crude oil mixed with some Russian oil for a period of time in the past few years. Overall, it yields a higher yield of light oil compared to processing Daqing crude oil alone, but equipment corrosion is also much more severe.

Hehe, 300 million tons spread over 20 years means 15 million tons per year – that’s not much either

The newly established Sino-Russian Oriental Petroleum Company plans to build a refinery with a capacity of 10 million tons in the Lingang Industrial Zone in Tanggu, Tianjin; it is said that feasibility studies are currently underway.

Liaoyang Petrochemical has a 5.5-million-ton atmospheric and vacuum distillation unit dedicated to processing Russian crude; didn’t Tianjin Petrochemical build a new 10-million-ton facility for processing Russian crude as well?

1. General properties of Russian crude oil: Russian crude oil has a low density, with a density of 0.8404 g/cm3 at 20°C. It also has low viscosity; the dynamic viscosities at 20°C and 50°C are 8.440 mm2/s and 3.426 mm2/s respectively. The acid value is low, at 0.20 mgKOH/g, and the wax content is low, at 4.36%. The freezing point is low, at -26°C. Russian crude oil has low levels of resin and asphaltenes, at 6.99% and 0.76% respectively; it has a higher sulfur content of 0.70%, a lower nitrogen content of 0.15%, a residue value of 2.39%, and an ash content of 0.010%. Based on the metal analysis results, the contents of nickel and vanadium are relatively high, at 6.34 μg/g and 6.53 μg/g respectively. 2. Actual boiling point distillation and properties of narrow fractions The actual boiling point distillation and properties of narrow fractions of Russian crude oil are listed in Table 2 ； The weight yield per 10°C fraction is listed in Table 3 ； The distillate volume yield per 10°C is listed in Table 4 ； The actual boiling point distillation and narrow fraction property curves are shown in Figures 1, 2, 3, and 4. As can be seen from Table 2, Russia has a high yield of light crude oils, with the yield of gasoline fractions at temperatures below 200°C being 28.15% ； The yield of gasoline and diesel fractions at <350℃ reaches 56.45% ； The yield of the <500℃ fraction is 81.44% ； ＜565℃ the overall extraction rate reaches as high as 87.40% ； > At 565°C, the residue yield is only 12.60%, indicating it is a light crude oil. The API grade of Russia’s first key crude distillate (250°C–275°C) is 36.7 ； The API value of the second key fraction (395°C–425°C) is 26.3. Classified according to the API gravity classification of key fractions, Russian crude oil belongs to sulfur-containing intermediate base crude oil. From the perspective of the properties of the narrow fraction, the general trend for sulfur content is that it increases as the boiling point rises; however, the sulfur content remains low between 60°C and 150°C. The relevant indices, density, and refractive index all reflect the characteristics of intermediate base crude oil.

The domestic central state-owned enterprises (Sinopec, CNOOC, CNPC) generally process Russian oil that enters through legitimate channels; it is of good quality. . . Domestic guerrilla producers (local refineries, private enterprises, individuals) can only process Russian M100. . . Haha. . . :lol

We started trying to incorporate Russian oil into our mix a long time ago. Although the Russian oil we purchase has a lower specific gravity, it becomes much heavier after atmospheric distillation and before catalytic processing. Every time we increase the proportion of Russian oil in the mix, it becomes more difficult for us to handle the process; sometimes we even have to reduce the amount used

I think our company (Daqing Petrochemical) should be able to carry out refining. However, I haven’t actually checked whether we only refine oil from the Daqing oil field, as I work in the downstream aromatic compounds sector... Russian crude oil is likely low in wax content and density, so it can only be used in blended form; the newly built facility in Tianjin is probably where the main refining takes place

At present, China mainly refines Russian oil from Daqing! The oil imported to Xinjiang mainly comes from Kazakhstan, and Dushanbe Petrochemical processes oil from Kazakhstan and Karamay! This year, Dushanzi Petrochemical will start operating with a capacity of 10 million tons in oil refining and 1 million tons in ethylene production; as a result, even more oil will need to be imported!

The Liaohe Refinery processes Russian crude oil, which is blended with Daqing crude oil, at a capacity of 5.5 million tons per year.

The Heilongjiang refinery was one of the first to process Russian crude oil. We conducted a comprehensive analysis; Russian crude is of lower density, and its use in blending leads to a significant increase in the yield of light products. However, it is a sulfur-containing crude, so equipment corrosion must be taken into account. Moreover, its use in jet fuel production is problematic, as it is difficult to control its smoke point. I hope we can communicate more.

Basic properties of Russian crude oil: The basic properties of Russian crude oil are shown in Table 1. As can be seen from the data in Table 1, the density of Russian crude oil at 20°C is low, at 837.9 kg/m3, and its dynamic viscosity at 50°C is also low, at 3.428 mm2/S. Due to its low wax content of 2.06%, this crude oil has a low freezing point of -20°C. The asphaltenes and resins content are 0.36% w/w and 5.34% w/w respectively, while the sulfur and nitrogen contents are 0.66% w/w and 0.13% w/w respectively. The salt content and acid value are 28 mg NaCl/l and 0.049 mg KOH/g respectively, and the residue and ash contents are 1.85% w/w and 0.011% w/w respectively. The contents of iron, nickel, copper, and vanadium in crude oil are 3.41 ppm, 5.75 ppm, 0.12 ppm, and 5.49 ppm respectively. In terms of the crude oil distillation range, the yield of fractions distilled before 300°C is relatively high at 51.9% (V%). Compared with North China crude, this crude oil has similar sulfur and nitrogen contents, lower density, wax content, and freezing point, more light components, and a higher vanadium content. As can be seen from Table 2, classified by key components and sulfur content, Russian crude oil belongs to the sulfur-containing-intermediate base crude oil category. 2.2 Actual boiling point distillation of Russian crude oil and properties of narrow fractions: The data on the actual boiling point distillation cuts of Russian crude oil as well as the properties of the narrow fractions are shown in Tables 3 and 4. The property curves for true boiling point distillation and narrow fractions are shown in Figures 1, 2, and 3. The actual boiling point distillation results show that Russian crude oil has high light oil and total recovery rates; the residue yield at 500°C is 16.79%, and its density is 1001.7 kg/m3 ； It has high contents of the metals nickel, iron, and vanadium, with 11.98% residual carbon. The results of the four-component analysis show a low content of saturated hydrocarbons, a high content of aromatic hydrocarbons, and a high content of asphaltenes; such a composition results in poor cracking performance, which is unfavorable for catalytic cracking processes. Therefore, this residue has unsatisfactory performance as a catalytic blend in heavy oil, and it can be considered as a feedstock for delayed coking. 3 Summary: 3.1 The Russian crude oil evaluated in this study is a light crude oil with low density, low freezing point, low wax content, low viscosity, low residue, a high yield of light oil, and a relatively high vanadium content. This crude oil belongs to the sulfur-containing – intermediate base crude oil category. 3.2 Based on the above evaluation results, this crude oil reforming feedstock has a high yield and a high aromatic potential content ； The yield of aviation kerosene fractions is high, and all analytical parameters except the smoke point meet the requirements for 3# jet fuel. It is more suitable for producing aromatic hydrocarbons and 3# jet fuel.

Dalian Petrochemical can also process Russian oil; its expansion and renovation were planned with the processing of Russian oil as well as Saudi Light oil in mind. Russian residue is a high-sulfur residue. It has a high sulfur content (around 1.5%), relatively high amounts of residual carbon (around 14%) and heavy metals (around 100 ppm), as well as a very high nitrogen content (around 4500 ppm).

Most refineries in the northeast process Russian oil via oil pipelines from Daqing to these refineries.
